RESUMO
BACKGROUND: Concomitant invasive ovarian mucinous adenocarcinoma, unilateral renal agenesis and bicornuate uterus is a rare combination. Unilateral renal agenesis has been associated with genital anomalies, such as unicornuate and bicornuate uterus. Furthermore, a wealth of studies has reported the association between unicornuate uterus and ovarian anomalies, such as the absence of an ovary or ectopic ovaries, but rarely has there been a combination of the three to the best of our knowledge. The present case report is the first case presentation with a combination of the three syndromes: ovarian mucinous tumor, unilateral renal agenesis, and bicornuate uterus. CASE PRESENTATION: We report the case of a 17-year-old who presented with abdominal distension. On examination, a CT scan revealed a large multicystic abdominal mass on the right side, with an absence of the right kidney while the left kidney was normal in size, appearance, and position. Intraoperatively, massive blood-stained ascitic fluid was evacuated. Additionally, a large whitish polycystic intra-abdominal mass with mucus-like materials and solid areas was attached to the midpoint of the colon and the right ovary, with visible metastasis to the omentum. The uterus was bicornuate. The mass and omentum were taken for histopathology and a diagnosis of invasive ovarian mucinous cystadenocarcinoma with metastasis to the colon and omentum was made after a pathological report. CONCLUSIONS: The presence of these conditions in the same individual could potentially complicate medical management and fertility considerations. Thus, a need for a multidisciplinary medical team, including gynecologists, urologists, and oncologists, to address their unique needs and provide appropriate treatment and guidance. Further research and case studies are needed to better understand the possible association and implications of these rare co-occurring conditions.

Tobacco use is a well-established risk factor for oesophageal squamous cell carcinoma (ESCC) but the extent of its contribution to the disease burden in the African oesophageal cancer corridor has not been comprehensively elucidated, including by type of tobacco use. We investigated the contribution of tobacco use (smoking and smokeless) to ESCC in Tanzania, Malawi and Kenya. Hospital-based ESCC case-control studies were conducted in the three countries. Incident cases and controls were interviewed using a comprehensive questionnaire which included questions on tobacco smoking and smokeless tobacco use. Logistic regression models were used to estimate odds ratios (OR) and their 95% confidence intervals (CI) of ESCC associated with tobacco, adjusted for age, sex, alcohol use, religion, education and area of residence. One thousand two hundred seventy-nine cases and 1345 controls were recruited between August 5, 2013, and May 24, 2020. Ever-tobacco use was associated with increased ESCC risk in all countries: Tanzania (OR 3.09, 95%CI 1.83-5.23), and in Malawi (OR 2.45, 95%CI 1.80-3.33) and lesser in Kenya (OR 1.37, 95%CI 0.94-2.00). Exclusive smokeless tobacco use was positively associated with ESCC risk, in Tanzania, Malawi and Kenya combined (OR 1.92, 95%CI 1.26-2.92). ESCC risk increased with tobacco smoking intensity and duration of smoking. Tobacco use is an important risk factor of ESCC in Tanzania, Malawi and Kenya. Our study provides evidence that smoking and smokeless tobacco cessation are imperative in reducing ESCC risk.

BACKGROUND: Blunt trauma to the urinary bladder is common with penetrating injury being a rare occasion. Most common entry pint for penetrating injuries includes buttock, abdomen and perineum with thigh being rare. There are a number of complications that may develop as a result of penetrating injury with vesicocutanous fistula being a rare occurrence that usually presents with typical sign and symptoms. CASE PRESENTATION: We present a rare case of penetrating bladder injury through medial upper thigh as an entry point that had complicated into vesicocutaneous fistula with atypical presentation of long-standing pus discharge that had been managed by incision and drainage several times with no success. MRI demonstrated a presence of fistula tract and a foreign body (piece of wood) in-situ confirmed the diagnosis. CONCLUSION: Fistulas are a rare complication of bladder injuries and can cause negative impact on the quality of life of patients. Delayed urinary tract fistulations and secondary thigh abscesses are uncommon therefore a high index of suspicion is needed for early diagnosis. This case emphasizes the importance of radiological tests in aiding the diagnosis and ultimately proper management.

INTRODUCTION: Mentorship is an essential component of research capacity building for young researchers in the health sciences. The mentorship environment in resource-limited settings is gradually improving. This article describes mentees' experiences in a mentorship program for junior academicians amid the COVID-19 pandemic in Tanzania. METHODS: This is a survey study that examined the experiences of mentees who participated in a mentorship program developed as part of the Transforming Health Education in Tanzania (THET) project. The THET project was funded by the US National Institutes of Health (NIH) under a consortium of three partnering academic institutions in Tanzania and two collaborating US-based institutions. Senior faculty members of respective academic institutions were designated as mentors of junior faculty. Quarterly reports submitted by mentees for the first four years of the mentorship program from 2018 to 2022 were used as data sources. RESULTS: The mentorship program included a total of 12 mentees equally selected from each of the three health training institutions in Tanzania. The majority (7/12) of the mentees in the program were males. All mentees had a master's degree, and the majorities (8/12) were members of Schools/Faculties of Medicine. Most mentors (9/10) were from Tanzania's three partnering health training institutions. All mentors had an academic rank of senior lecturer or professor. Despite the onset of the COVID-19 pandemic, the regular weekly meetings between mentors and mentees were not affected. By the fourth year of the mentorship program, more than three-quarters of mentees had published research related to the mentorship program in a peer-reviewed journal, over half had enrolled in Ph.D. studies, and half had applied for and won competitive grant awards. Almost all mentees reported being satisfied with the mentorship program and their achievements. CONCLUSION: The mentorship program enhanced the skills and experiences of the mentees as evidenced by the quality of their research outputs and their dissemination of research findings. The mentorship program encouraged mentees to further their education and enhanced other skills such as grant writing. These results support the initiation of similar mentorship programs in other institutions to expand their capacity in biomedical, social, and clinical research, especially in resource-limited settings, such as Sub-Saharan Africa.

BACKGROUND: Consumption of very-hot beverages/food is a probable carcinogen. In East Africa, we investigated esophageal squamous cell carcinoma (ESCC) risk in relation to four thermal exposure metrics separately and in a combined score. METHODS: From the ESCCAPE case-control studies in Blantyre, Malawi (2017-20) and Kilimanjaro, Tanzania (2015-19), we used logistic regression models adjusted for country, age, sex, alcohol and tobacco, to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for self-reported thermal exposures whilst consuming tea, coffee and/or porridge. RESULTS: The study included 849 cases and 906 controls. All metrics were positively associated with ESCC: temperature of drink/food (OR 1.92 (95% CI: 1.50, 2.46) for 'very hot' vs 'hot'), waiting time before drinking/eating (1.76 (1.37, 2.26) for <2 vs 2-5 minutes), consumption speed (2.23 (1.78, 2.79) for 'normal' vs 'slow') and mouth burning (1.90 (1.19, 3.01) for ≥6 burns per month vs none). Amongst consumers, the composite score ranged from 1 to 12, and ESCC risk increased with higher scores, reaching an OR of 4.6 (2.1, 10.0) for scores of ≥9 vs 3. CONCLUSIONS: Thermal exposure metrics were strongly associated with ESCC risk. Avoidance of very-hot food/beverage consumption may contribute to the prevention of ESCC in East Africa.

BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is a major cause of cancer morbidity and mortality in Eastern Africa. The majority of patients with ESCC in Eastern Africa present with advanced disease at the time of diagnosis. Several palliative interventions for ESCC are currently in use within the region, including chemotherapy, radiation therapy with and without chemotherapy, and esophageal stenting with self-expandable metallic stents; however, the comparative effectiveness of these interventions in a low resource setting has yet to be examined. METHODS: This prospective, observational, multi-center, open cohort study aims to describe the therapeutic landscape of ESCC in Eastern Africa and investigate the outcomes of different treatment strategies within the region. The 4.5-year study will recruit at a total of six sites in Kenya, Malawi and Tanzania (Ocean Road Cancer Institute and Muhimbili National Hospital in Dar es Salaam, Tanzania; Kilimanjaro Christian Medical Center in Moshi, Tanzania; Tenwek Hospital in Bomet, Kenya; Moi Teaching and Referral Hospital in Eldoret, Kenya; and Kamuzu Central Hospital in Lilongwe, Malawi). Treatment outcomes that will be evaluated include overall survival, quality of life (QOL) and safety. All patients (≥18 years old) who present to participating sites with a histopathologically-confirmed or presumptive clinical diagnosis of ESCC based on endoscopy or barium swallow will be recruited to participate. Key clinical and treatment-related data including standardized QOL metrics will be collected at study enrollment, 1 month following treatment, 3 months following treatment, and thereafter at 3-month intervals until death. Vital status and QOL data will be collected through mobile phone outreach. DISCUSSION: This study will be the first study to prospectively compare ESCC treatment strategies in Eastern Africa, and the first to investigate QOL benefits associated with different treatments in sub-Saharan Africa. Findings from this study will help define optimal management strategies for ESCC in Eastern Africa and other resource-limited settings and will serve as a benchmark for future research. TRIAL REGISTRATION: This study was retrospectively registered with the ClinicalTrials.gov database on December 15, 2021, NCT05177393 .

BACKGROUND: Minimally invasive tissue sampling (MITS) is a useful tool to determine cause of death in low- and middle-income countries (LMICs). In 2019 the MITS Surveillance Alliance supported the implementation of small-scale postmortem studies using MITS in several LMICs. METHODS: In this article we describe the preparations, challenges, and lessons learned as part of implementing MITS across 4 study sites in 3 countries: Nepal, Rwanda, and Tanzania. We describe the process for building capacity to conduct MITS, which consisted of training in MITS sample collection, individual site assessment to determine readiness and gaps prior to implementation, site visits as sites began implementation of MITS, and feedback based on remote evaluation of histology slides via an online portal. RESULTS: The 4 study sites each conducted 100 MITS, for a total of 400. All 4 sites lacked sufficient infrastructure and facilities to conduct MITS, and upgrades were required. Common challenges faced by sites included that clinical autopsies were neither routinely conducted nor widely accepted. Limited clinical records made cause of death determination more difficult. Lessons learned included the importance of sensitization of the community and medical staff to MITS to enhance understanding and increase consent. CONCLUSIONS: The study sites accomplished MITS and utilized the available support systems to overcome the challenges. The quality of the procedures was satisfactory and was facilitated through the organized capacity-building programs.

Esophageal sponge cytology is an endoscopy alternative well accepted by patients with extensive data for accuracy in the context of adenocarcinoma. Few studies have assessed its feasibility in asymptomatic community members, and fewer still in East Africa, where esophageal squamous cell carcinoma (ESCC) rates are high. We aimed to assess the feasibility of a capsule-based diagnosis of esophageal squamous dysplasia (ESD), an ESCC precursor, which may benefit epidemiological and early detection research. We collected Cytosponge collections in 102 asymptomatic adults from Kilimanjaro, Tanzania. Uptake, acceptability and safety were assessed. Participants scored acceptability immediately following the procedure and 7 days later on a scale of 0 (least) to 10 (most acceptable). Slides from paraffin-embedded cell clots were read by two pathologists for ESD and other pathologies. All participants (52 men, 50 women, aged 30-77) swallowed the device at first attempt, 100 (98%) of which gave slides of adequate cellularity. Acceptability scores were 10 (53%), 9 (24%), 8 (21%), 7 (2%) and 6 (1%), with no differences by age, sex or time of asking. Cytological findings were esophageal inflammation (4%), atypical squamous cells of uncertain significance (1%), low-grade dysplasia (1%), gastritis (22%) and suspected intestinal metaplasia (6%). Setting-specific logistical and ethical considerations of study implementation are discussed. We demonstrate the safety, acceptability and feasibility of Cytosponge sampling in this setting, paving the way for innovative etiology and early-detection research. Targeted sampling strategies and biomarker development will underpin the success of such initiatives. The study protocol is registered on ClinicalTrials.gov (NCT04090554).

In the African esophageal squamous cell carcinoma (ESCC) corridor, recent work from Kenya found increased ESCC risk associated with poor oral health, including an ill-understood association with dental fluorosis. We examined these associations in a Tanzanian study, which included examination of potential biases influencing the latter association. This age and sex frequency-matched case-control study included 310 ESCC cases and 313 hospital visitor/patient controls. Exposures included self-reported oral hygiene and nondental observer assessed decayed+missing+filled tooth count (DMFT index) and the Thylstrup-Fejerskov dental fluorosis index (TFI). Blind to this nondental observer TFI, a dentist independently assessed fluorosis on photographs of 75 participants. Odds ratios (ORs) are adjusted for demographic factors, alcohol and tobacco. ESCC risk was associated with using a chewed stick to brush teeth (OR 2.3 [95% CI: 1.3-4.1]), using charcoal to whiten teeth (OR 2.13 [95% CI: 1.3, 4.1]) and linearly with the DMFT index (OR 3.3 95% CI: [1.8, 6.0] for ≥10 vs 0). Nondental observer-assessed fluorosis was strongly associated with ESCC risk (OR 13.5 [95% CI: 5.7-31.9] for TFI 5+ v 0). However, the professional dentist's assessment indicated that only 43% (10/23) of participants assessed as TFI 5+ actually had fluorosis. In summary, using oral charcoal, brushing with a chewed stick and missing/decayed teeth may be risk factors for ESCC in Tanzania, for which dose-response and mechanistic research is needed. Links of ESCC with "dental fluorosis" suffered from severe exposure misclassification, rendering it impossible to disentangle any effects of fluorosis, extrinsic staining or reverse causality.
RESUMO
INTRODUCTION: The objective was to determine if self-collection of vaginal samples for human papillomavirus (HPV) testing was acceptable and feasible in rural Tanzania and to assess the extent of attendance at a follow-up appointment among women who tested HPV-positive after delivery of HPV results via text messages. MATERIAL AND METHODS: A combined cross-sectional and cohort study was conducted among women aged 25-60 years from rural Kilimanjaro, Tanzania. Women were offered HPV self-sampling or traditional visual inspection of the cervix with acetic acid. If HPV self-sampling was preferred, participants received instructions on self-collection with an Evalyn Brush. A questionnaire was used to assess the acceptability and feasibility of the self-sampling procedure for the participants and delivery of HPV results via text messages. A mobile text message platform was used to send private text messages with the screening results to the participants. RESULTS: A total of 1108 women were enrolled and self-collected an HPV sample; 11.8% tested positive for high-risk HPV. The majority (98.9%) agreed that they had no trouble in understanding the instructions on how to perform the self-collection and that they would recommend it to a friend (94.5%) or as a standard screening method in Tanzania (95.5%). A minority of women experienced bleeding (2.4%) or pain (6%) while collecting the sample, while some were worried that they would get hurt (12.7%) or felt embarrassed (3.5%). The majority (98.4%) of women would like to receive the screening test results via text messages. Eighty-two per cent of those who tested positive for high-risk HPV attended the follow-up appointment after receiving a text message reminder and an additional 16% attended after receiving both a text message and a phone call reminder whereas 2% did not attend follow up at all. Attendance was not influenced by age, marital status, education level, parity, or HIV status. CONCLUSIONS: Human papillomavirus self-sampling and text-message feedback delivery are generally well-perceived and accepted among rural Tanzanian women, and the majority of HPV-positive women attended a follow-up appointment after receiving their HPV results and follow-up appointment via text messages. This screening method may have potential to be transferrable to other low-income countries with a high incidence of cervical cancer and so improve cervical cancer screening attendances.

INTRODUCTION: A significant number of climbers on Mount Kilimanjaro are affected by altitude-related disorders. The aim of this study was to determine the main causes of morbidity and mortality in a representative cohort of climbers based on local hospital records. METHODS: We conducted a 2-y retrospective chart review of all patients presenting to the main referral hospital in the region after a climb on Mount Kilimanjaro, including all relevant records and referrals for postmortem studies. RESULTS: We identified 62 climbers who presented to the hospital: 47 inpatients and 15 outpatients. Fifty-six presented with high altitude illness, which included acute mountain sickness (n=8; 14%), high altitude pulmonary edema (HAPE) (n=30; 54%), high altitude cerebral edema (HACE) (n=7; 12%), and combined HAPE/HACE (n=11; 20%). The mean altitude of symptom onset ranged from 4600±750 m for HAPE to 5000±430 m for HAPE/HACE. The vast majority of inpatients (n=41; 87%) were improved on discharge. Twenty-one deceased climbers, most having died while climbing (n=17; 81%), underwent postmortem evaluation. Causes of death were HAPE (n=16; 76%), HAPE/HACE (n=3; 14%), trauma (1), and cardiopulmonary (1). CONCLUSIONS: HAPE was the main cause of death during climbing as well as for hospital admissions. The vast majority of climbers who presented to hospital made a full recovery.

BACKGROUND: Hysterectomy is one of the most common gynaecological procedures performed worldwide. The magnitude of the complications related to hysterectomy and their risk factors are bound to differ based on locations, availability of resources and level of surgical training. Documented complications rates and their correlates are reported from high income countries while data from low- and middle-income countries including Tanzania is scare. METHODS: This was a hospital based cross-sectional study conducted at a tertiary facility in northern Tanzania where 178 women who underwent elective gynecological hysterectomies in the department of obstetrics and gynecology within the study period were enrolled. Logistic regression was performed to determine the association between risk factors and occurrence of surgical complication where p-value of < 0.05 was considered statistically significant. The degree of correlation between pre-operative clinical and histological diagnosis was determined by kappa correlation test. RESULTS: A total of 75 (42%) of women had surgical complications within 10 days of surgery. Blood transfusion and intra-operative bleeding were the most common complications observed in 34 (19.1%) and 17 (9.6%) women respectively. Independent risk factors for complications included obesity (OR 3.9; 95% CI 1.44-10.46), previous abdominal operations (OR 8.44; 95% CI 2.52-28.26) and longer duration of operation (> 2 h) (OR 5.02; 95% CI 2.18-11.5). Both uterine fibroid and adenomyosis had good correlation of clinical and histological diagnosis (p-value < 0.001). CONCLUSION: Bleeding and blood transfusion were the most common complications observed in this study. Obesity, previous abdominal operation and prolonged duration of operation were the most significant risk factors for the complications. Local tailored interventions to reduce surgical complications of hysterectomy are thus pivotal. Clinicians in this locality should have resources at their disposal to enhance definitive diagnosis attainment before surgical interventions.

BACKGROUND: Kaposi's sarcoma (KS) is a multifocal angioproliferative tumor involving blood and lymphatic vessels, caused by Human Herpes Virus-8 (HHV-8). KS is an important AIDS-defining tumor with high prevalence in Sub-Saharan Africa, including Tanzania which has high HIV and HHV-8 sero-prevalence. It is critically important to monitor the prevalence of AIDS-defining tumors, such as KS, in the age of HIV/AIDS. We studied the prevalence of KS and associated risk factors among HIV-positive patients at Kilimanjaro Christian Medical Centre (KCMC), a referral hospital in northern Tanzania, over the period from January 2012 to December 2015. METHODS: This was a retrospective hospital-based cross-sectional study to determine the prevalence of KS among HIV/AIDS patients between 2012 and 2015. The study included 1100 HIV patients' data which were collected at the Infectious Disease Clinic (IDC) from patients' files. Stata version 13 (StataCorp LP, Texas 77,845 USA) was used for all statistical analyses. The prevalence of KS was calculated across levels of a number of categorical variables. Logistic regression was performed to determine relative risk of KS for all characteristics. We included all variables with p-values ≤10% in the multivariate analysis, including ART use, as this is considered to have an influence on KS. In the multivariate analysis, statistical significance was established based on a two-tailed p-value ≤5%. All patients' notes were kept confidential as per the Helsinki declaration. RESULTS: Our results revealed a 4.6% prevalence of KS at KCMC hospital, between January 2012 and December 2015, 51(4.6%) patients were diagnosed with KS out of 1100 HIV-positive patients. The study further revealed that KS in HIV patients was most associated with low CD4 cell count (less than or equal to 200 cells/µl). Moreover, women were more likely than men to diagnosed with KS, with higher odds significantly associated with KS (OR 0.42, p < 0.009). Increased age, above 35 years, among the HIV seropositive patients was significantly associated with KS (OR 25.67, p < 0.007). HIV patients who were none smokers were more likely to suffer from KS compared to HIV smokers (OR 0.41, p < 0.010). CONCLUSION: KS remains a common malignant vascular tumor commonly associated with HIV/AIDS in Tanzania. Our study highlights the need for continued efforts to combat HIV, as well as associated diseases such as KS. Continued availability of ART (Anti-Retroviral Therapy) to HIV/AIDS patients, and test reagents for CD4 cell count and viral load determination are important measures to alleviate the suffering of these patients. Furthermore, studies to gather more evidence on ART resistance are highly needed to guide treatment choices.

BACKGROUND: Colorectal cancer associated with chronic intestinal schistosomiasis has been linked with the chronic inflammation as a result of schistosomal ova deposition in the submucosal layer of the intestine. Among all species Schistosoma japonicum has been more linked to development of colorectal cancer as compared to Schistosoma mansoni due to absence of population-based studies to support the association. Despite the weak evidence, some cases have been reported associating S. mansoni with development of colorectal cancer. CASE PRESENTATION: We report a patient who presented to us as a case of intestinal obstruction and found to have a constrictive lesion at the sigmoid colon at laparotomy, then later found to have colorectal cancer with deposited S. mansoni ova at histology. CONCLUSION: Given the known late complications of schistosomiasis, and as S. mansoni is endemic in some parts of Tanzania, epidemiological studies are recommended to shed more light on its association with colorectal cancer.

Key Clinical Message: Gestational macromastia is a rare disorder involving excessive breast tissue enlargement during pregnancy, potentially threatening the fetus and the mother. Our patient's previous pregnancies were more physiological, without any associated symptoms. Abstract: Moderate bilateral enlargement of the breasts is a normal finding during pregnancy and lactation. Occasionally, there is a continuity from this physiological hypertrophy to massive breast hyperplasia or gigantomastia, causing complications that threaten the wellbeing of the fetus and the mother or raising alarm for a malignant disease. We present a case of a 28-year-old G3P2L2 with a gestational age of 29 weeks complaining of massive bilateral breast enlargement for 6 months, accompanied by a threatened abortion. The masses began gradually after conception and increased gradually over time. Notably, the breasts had been unremarkable in her two previous pregnancies. The breast ultrasonography and mammography findings pointed to a benign neoplasm. Histopathology of the lesions reported bilateral ductal hyperplasia. Conservative management and close follow-up were initiated. A cesarean section was performed due to cord prolapse, and a 1.3 kg male baby was extracted. Unfortunately, the neonate succumbed after 3 days due to apnea of prematurity. The patients' breast size subsided considerably with time. Unusually large tumors can cause alarm for other pathologies, such as breast cancer. The radiological tests should reassure the attending practitioner, and the histological examination should confirm the diagnosis. An understanding of the typical and atypical clinico-pathologic characteristics of breast lesions occurring in pregnancy and lactation is essential for appropriate patient care.
RESUMO
Liposarcoma is a tumor derived from primitive cells that undergo adipose differentiation. They comprise 10%-35% of all soft tissue sarcomas. We present a 46-year-old female patient with a 4-year history of a giant swelling on the lateral aspect of the left thigh. Wide local excision of the mass was performed and histopathological analysis revealed a well-differentiated liposarcoma. Liposarcomas commonly appear in the extremities and have distinct features on imaging studies. Surgical treatment and histology are the most important prognostic factors for patients with lipomatous tumors, as complete surgical excision reduces local recurrence rate.
RESUMO
Key Clinical Message: Rhabdomyosarcoma of the female genital tract often involves the vagina and cervix. It usually occurs in infants and children. Such tumors are uncommon in the uterus, especially in adults. Treatment options are based on studies of younger individuals. Abstract: Rhabdomyosarcoma (RMS) is a malignant mesenchymal neoplasm with a tendency to differentiate into skeletal muscle cells. RMS is an aggressive tumor that tends to develop in children and younger patients. A vast majority of genital tract RMSs occur in the vagina and cervix. Such tumors rarely occur in adults. Usually, these tumors either occur as a component of a biphasic uterine tumor (carcinosarcoma or adenosarcoma) or can be a pure heterologous tumor. Pure uterine RMSs are extremely rare in adult patients and difficult to diagnose. Accurate diagnosis of these tumors depends on precise histopathological evaluation. The present report describes a rare case of embryonal RMS of the uterus in a postmenopausal female and explores the most recent literature. The aim is to strengthen the existing literature and aid clinicians in the management of similar cases. A 64-year-old postmenopausal female presented with a history of abdominal pain associated with abdominal distension, per vaginal bleeding, and foul-smelling discharge for 6 months. A transabdominal ultrasound revealed a bulky uterus with a well-circumscribed heterogeneous lesion. Histopathology confirmed the diagnosis of high-grade embryonal RMS within the corpus region of the uterus. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed, followed by adjuvant chemotherapy to prevent relapse of the disease. Six months after oncological care has passed, the patient remains symptoms-free without evidence of recurrence or metastasis.
RESUMO
Ossifying fibroma (OF) is a slow-growing benign fibro-osseous neoplasm. It is mostly odontogenic in origin, and it arises in the jaws, particularly the mandible. OF is characterized by the production of bone and cementum-like calcifications in a fibrous stroma. OF reports of the bone of the maxilla are uncommon. Diagnosing OF can be challenging due to the considerable overlap of clinico-pathological characteristics with those of other neoplasms. Herein, the authors describe a case report OF in a 26-year-old male who presented with a huge fibro-osseous tumor of the maxilla. Histopathology established the diagnosis of maxillary OF. The tumor was surgically removed via a Weber-erguson approach with satisfactory functional and cosmetic results. No recurrence has been found after one year of follow-up. Clinical, radiological, and pathological characteristics, as well as surgical treatment approaches, are further discussed. This is one of a few documented cases of maxillary OF in our setting.
RESUMO
INTRODUCTION AND IMPORTANCE: A cervical stump fibroid is a rare type of leiomyoma (fibroid) that occurs in the remaining cervical tissue following a subtotal hysterectomy. In this procedure the uterus is removed but the cervix is left intact. Cervical stump fibroids are quite rare, with studies indicating that they occur in less than 1 % of women who have undergone subtotal hysterectomy. The present report describes a rare case of uterine fibroid arising from the cervical stump 7 years after subtotal hysterectomy. The aim is to strengthen the existing literature and aid clinicians in the management of similar cases. CASE PRESENTATION: A 45-year-old female presented with a history of abdominal distension, abdominal pain, and bilateral lower limb swelling for 1 year. An abdominal Computed Tomography (CT) scan with contrast and Magnetic Resonance Imaging (MRI) revealed a large multilobulated mass in the pelvis measuring 14.3 × 7.4 × 21.1 cm. The mass displaces and compresses the urinary bladder anteriorly and the rectosigmoid colon posteriorly. Additionally, there is compression of the distal ureters bilaterally with resultant bilateral hydroureteronephrosis. The patient underwent explorative laparotomy and post-operative recovery was uneventful. The final histopathological report showed the diagnosis of uterine fibroid. CLINICAL DISCUSSION: In this case report, we discuss the condition's rarity, related reports in the literature, and the numerous difficulties clinicians face when encountering a patient with cervical leiomyomas. CONCLUSION: This case highlights the importance of long-term follow-up for patients post-supracervical hysterectomy, adds to the existing literature, and provides insight to healthcare providers in handling similar cases. Patients who are affected should receive appropriate counseling on postoperative care, recurrence after treatment, and the value of early and regular follow-up visits.
RESUMO
INTRODUCTION AND IMPORTANCE: Cystic hygroma is a benign congenital malformation of lymphatic and blood vessels, with an incidence of 1 in 6000 live births. Most cases are associated with genetic syndromes and can compromise fetal viability. Due to its rarity, comprehensive data is limited, mainly relying on case reports. CASE PRESENTATION: A 21-year-old pregnant woman at 27 weeks' gestation presented to triage with abdominal pain. Abdominal ultrasound revealed a single living female fetus with an estimated fetal weight of 734 g and a complex cystic mass causing hyper-extension of the neck. The pregnancy was terminated given the poor prognosis. Histopathology of the mass confirmed it to be a cystic hygroma. CLINICAL DISCUSSION: In limited-resource settings, management of huge cystic hygromas often necessitates termination of pregnancy due to a lack of sufficient resources for complex interdisciplinary interventions for the mother and infant after birth. In such cases, focus should be shifted toward promoting shared decision-making and sensitive patient counseling. CONCLUSION: Cystic hygromas that are diagnosed prenatally generally have a poorer prognosis than those diagnosed after birth. The management of cystic hygramas, particularly those diagnosed prenatally, represents a persistent challenge in low-resourced settings. Counseling and treatment recommendations must be tailored based on tumor characteristics, the expected prognosis, and the feasibility of medical or surgical intervention in a given clinical environment.
