Xanthogranulomatous Salpingo-Oophoritis as a Rare Presentation in Pelvic Inflammatory Disease.

Xanthogranulomatous salpingo-oophoritis is an infrequent and challenging inflammatory condition of the female genital tract. It involves the destruction of the fallopian tube and ovarian tissue by infiltrating inflammatory cells comprising lipid-laden macrophages, lymphocytes, plasma cells, and multinucleated giant cells. While more commonly found in other organs like the gallbladder and kidney, its occurrence in the female genital tract is rare. We present a case of xanthogranulomatous salpingo-oophoritis in a 45-year-old woman, shedding light on its diagnostic and clinical complexities. Notably, this case features a rare histopathological finding of coexisting salpingitis isthmic nodosa (SIN) with xanthogranulomatous inflammation, adding to its uniqueness.

Is routine gastrointestinal endoscopy required in every woman with mucinous ovarian cancer? An analysis of survival rates and metastatic tumours in a cancer centre.

INTRODUCTION: Mucinous ovarian cancer (MOC) represents a rare entity of ovarian malignant neoplasms. The true incidence could be as low as 3% of all ovarian cancers. The aim of this study is to compare and understand the clinicopathological characteristics of patients with mucinous ovarian cancer, report on the survival rates and evaluate the role of gastrointestinal (GI) endoscopy as part of the peri-operative investigations and the impact it has on the survival rates. METHODOLOGY: This is a retrospective data collection on patients with MOC operated in Nottingham gynaecological oncology centre over a 10-year period. Data were analysed using SPSS software. RESULTS: 43 cases were included in the final analysis. The median maximal tumour diameter was 180 mm. 32 (74.5 %) and 11 (25.5 %) women presented with unilateral and bilateral tumours respectively. 30 patients (69.7 %) presented with stage 1 disease, 1 (2.3 %) presented with stage 2 disease, 7 women (16.4 %) had stage 3 disease and 1 woman (11.6 %) had stage 4 disease. 41 women had staging surgical procedures and 2 women had limited surgery due to poor performance status. After final histology, 5 cases found to have metastatic disease to the ovary rather than primary MOC. 14 women had GI endoscopy as part of their investigation. The total estimated cost of the endoscopies that have been performed is £5635. Primary GI cancer was diagnosed in 1 case during the endoscopy (1 case of gastric cancer). The 5-year overall survival of the women included in this study is 62.8 %. The 5-year overall survival of the women in the endoscopy and non-endoscopy groups was 60 % and 64.3 % respectively (p-value: 0.767). CONCLUSION: The findings of this study show that the survival rates of patients treated for mucinous ovarian cancer in our centre are similar to other published studies. Our findings do not support the routine use of GI endoscopy in the peri-operative investigations of every patient with MOC due to the non-statistically significant difference in the overall survival.

Posterior Surgical Ligation and Cyst Decompression -via Needle Puncture- of a Large Anterior Sacral Pelvic Meningocele Through Posterior Sacral Laminectomy.

The first documented description of an anterior sacral meningocele was Bryant's in 1823. Anterior sacral meningocele patients have constipation as a universal symptom; urinary incontinence is also common. All the symptoms are directly related to the pressure from a pelvic mass on adjacent structures. When the patient stands, a headache often develops because the spinal fluid pressure decreases as the meningocele sac fills. Finally, a scimitar-shaped sacrum on a neuroradiological anteroposterior plain assessment is pathognomonic. The coccyx may be absent, and the lower sacral laminae may be absent or incomplete. The surgical options for this rare clinical condition are still matter of debate.Anterior sacral meningocele is a pathology that lacks a current classification and neurosurgical therapeutic standards, even though a similar dynamic has been shown by the related traumatic pseudomeningocele. Anterior approaches (retro- and transperitoneal meningocele neck occlusion with internal cerebrospinal fluid (CSF) cyst drainage) and posterior approaches (posterior sacral laminectomy, dural sac ligation, and CSF cyst drainage) are the available surgical strategies.We now report the case of an adult patient for whom a posterior approach was suggested and performed and report her postoperative surgical follow-up. The surgical rationale is also discussed.

Robot-Assisted Extraperitoneal Radical Prostatectomy for Giant Multilocular Prostatic Cystadenoma: A Case Report and Literature Review.

A 48-year-old man with a medical history of hypertension and no family history of prostate cancer presented with abdominal distension, lower abdominal pain, and lower urinary symptoms. Physical examination revealed a palpable mass in the lower abdomen, and a digital rectal examination detected a firm mass on the anterior side of the rectum. Laboratory tests showed an elevated PSA level (7.9 ng/mL). Imaging studies indicated a solid mass connected to the prostate's posterior and rectum's anterior walls, along with bladder compression. Transperitoneal biopsy and histological analysis led to a diagnosis of a stromal tumor with uncertain potential malignancy. Considering the absence of apparent malignancy signs and the smooth outer wall of the tumor, the patient underwent, for the first time in the literature, a robot-assisted radical extraperitoneal prostatectomy for complete macroscopic resection. The surgery involved excision of the bulky pelvic mass, preservation of the urethra, and anatomical reconstruction. The postoperative course was uneventful, and we discharged the patient with no complications. The pathological examination documented the diagnosis of multilocular prostatic cystadenoma. Post-surgery follow-up examinations, including PSA levels and imaging scans, showed no signs of tumor recurrence. At the 3-, 6-, and 9-month follow-ups, the patient was asymptomatic and had fully recovered, with no urinary or sexual dysfunction reported.

Clinical value of quantitative analysis of contrast-enhanced ultrasonography in the differential diagnosis of benign and malignant pelvic tumors.

Background: Cervical cancer, endometrial cancer, and ovarian cancer are among the top 10 most common cancers in women, with ovarian cancer in particular being considered a "silent killer". Therefore, early detection, diagnosis, and treatment constitute important means of care for women's health. This study investigated the clinical value of the quantitative analysis of contrast-enhanced ultrasonography (CEUS) in the differential diagnosis of benign and malignant pelvic tumors. Methods: CEUS was performed on 151 patients with pelvic masses. Subsequently, a qualitative diagnosis was completed using the image enhancement features and tumor parameters. A multiparametric analysis of CEUS images was performed, which included the following parameters: arrival time (AT), time to peak (TTP), peak intensity (PI), and ascent slope (AS). In addition, the qualitative diagnostic efficiency of CEUS was assessed in a multiparametric analysis, and the results were compared with pathological findings. Results: The patients in the malignant group were older (P=0.001) and had larger lesion PI values (P<0.01) than those in the benign group. The PI difference (PId) and the AS difference (ASd) showed statistical differences (P<0.01) between the myometrium and lesion tissues in the same patient. Moreover, the PId and ASd showed the largest receiver operating characteristic (ROC) curve and area under the ROC curve (AUC), with sensitivities of 90.9% and 91.7% and specificities of 86.4% and 72.5%, respectively. Conclusions: The quantitative analysis of CEUS provides a new, simpler, and more accurate method for the differential diagnosis of benign and malignant pelvic masses in clinical practice. The sensitivities and specificities of PId and ASd were higher compared to other parameters from the same patient.

Nontuberculous mycobacterial infection mimicking gynecologic malignancy in a woman living with HIV.

The weakened immune system in people living with HIV (PLWH) can lead to infectious diseases occurring more aggressively and mimicking the clinical manifestations of malignancies. Mycobacterium sherrisii, a slow-growing nontuberculous mycobacterium, may cause opportunistic infections among PLWH. We present a case of a 41-year-old woman who initially presented with fever, vaginal spotting, and a bulky pelvic mass, raising suspicion of uterine malignancy. Following a surgical resection, she was pathologically diagnosed with leiomyoma and endometriosis. However, during an event of needlestick injury, she was unexpectedly found to be HIV-infected and the CD4 count was 157 cells/µL at diagnosis, which prompted a diagnostic work-up for opportunistic infections. The diagnosis of disseminated M. sherrisii infection was confirmed through cultures and special staining of specimens obtained from the pelvic tumor and blood. Subsequently, she was treated with a combination of ethambutol, azithromycin, and levofloxacin. Two months after treatment, abdominal and pelvic computed tomography revealed no evidence of recurrent tumor or abscess formation. Given the frequent association of pelvic masses with gynecologic malignancies in women living with HIV, it can be challenging to differentiate between a cancerous lesion and an infectious process, emphasizing the need for meticulous investigations to minimize the potential for misdiagnosis.

Intracardiac Leiomyomatosis Arising from a Uterine Leiomyoma - A Rare Case Requiring a Multidisciplinary Laparotomy-Thoracotomy Approach.

A 37-year-old lady, when being evaluated in gynecology for pain in the abdomen, was found to have a pelvic mass suspicious of ovarian cancer with markers negative. There was an ovarian vein thrombosis extending to the right atrium in the contrast-enhanced computed tomography scan. A fluorodeoxyglucose positron emission tomography-computed tomography ruled out any other lesions. The patient underwent surgery under general anesthesia with transesophageal echocardiography to monitor the atrial thrombus. Intraoperatively, a retroperitoneal mass is seen arising from the right adnexal region of the uterus extending to the lumbar area. After the hysterectomy, bilateral salpingo-oophorectomy, tumor resection, and baring and looping of the retroperitoneal vessels, a sternotomy was done, and she was put on cardiopulmonary bypass. The tumor thrombus had two limbs both arising from the mass, one through the ovarian and the second through the iliac veins and joining together inside the inferior vena cava (IVC). With the excision of the ovarian vein at its junction, atrial incision, and incisions over the iliac veins and IVC, the thrombus was removed completely in a single sitting. Final histopathology revealed intravenous leiomyomatosis and no malignancy. We report this case as a rare disease, with both ovarian and iliac thrombus being a further rarity and a multidepartment joint effort with a successful outcome.

Reevaluation of Large Pelvic Masses after Inconclusive MRIs: A Case Report.

The lack of a classification system addressing the size of pelvic masses challenges their evaluation. The American College of Obstetricians and Gynecologists recommends using an ultrasound (US) as the first-line modality, followed by magnetic resonance imaging (MRI). However, these do not guarantee optimal assessment. We present a case of a 36-year-old woman with a large pelvic mass of unknown etiology, after being evaluated with US, a computed tomography scan, and MRI. A reassessment by a US-specialized radiologist found a stalk (≥2.0 cm) with internal bridging vessels at the uterine fundus. The mass was identified as a pedunculated myoma and removed en bloc during a total abdominal hysterectomy with a bilateral salpingectomy and an oophoropexy. A reassessment by a US-specialized radiologist could be beneficial for cases of pelvic masses with unknown etiology after an evaluation with multiple imagining studies. These specialists possess extensive knowledge and vast expertise, potentially allowing US evaluations to be more effective than MRIs.

Unusual Vulvar, Perineal, and Uterine Leiomyomas: A Case Report.

Vulvar leiomyomas are extremely rare smooth muscle tumors that are easily mistaken for other lesions, as the differential diagnosis must consider a wide spectrum of benign and malignant lesions. We present the case of a 52-year-old woman with a three-year history of progressive abdominal distension and pain and an enlarging vulvar mass distorting the labia majora and causing gait disturbance. Imaging confirmed an enormous pelvic mass originating in the uterus, compatible with a leiomyoma/sarcoma, and large perineal and vulvar masses with similar characteristics. Histopathology after surgical removal revealed benign abdominal, vulvar, and perineal leiomyomas. This case highlights the rarity and diagnostic challenges of extra-uterine leiomyomas, particularly those in the vulvar region.

Case Report: Pelvic mass and massive ascites as the first symptom in cervical adenocarcinoma: report of two cases and literature review.

Cervical adenocarcinoma accounts for 10%-25% of total cases of cervical carcinoma. But in recent years, the incidence of adenocarcinoma has risen both proportionally and absolutely. Clinically, most cervical adenocarcinoma show no symptom or present with abnormal uterine bleeding or vaginal discharge, similar to squamous cell carcinoma. What different about it is that cervical cytological testing demonstrates a high false-negative rate of cervical adenocarcinoma, potentially leading to the failure in detecting in early stage. This report presents two cases both with pelvic masses, and massive ascites served as the initial symptom, which is similar to the clinical symptom of ovarian cancer, but ultimately diagnosed with cervical adenocarcinoma through surgical specimens. There are few literature reports on this situation. Hence, a literature review also has been performed to improve the recognition for cervical adenocarcinoma presenting with pelvic masses and massive ascites, and to avoid misdiagnosis.

A diagnostic challenge; pelvic solitary fibrous tumor (SFT) mimicking Peri-Anal gastrointestinal stromal tumor (GIST): A case report.

Key Clinical Message: The study reports a rare case of pelvic solitary fibrous tumor (SFT) that was initially considered as a peri-anal gastrointestinal stromal tumor due to similar radiologic/pathologic features. SFT diagnosis can be challenging due to its rarity and wide range of diagnoses that must be ruled out precisely. Abstract: Solitary fibrous tumors (SFTs) are rare tumors that can occur in any part of the body. Although usually benign, malignant SFTs have been reported, especially outside the lungs. Radiology can help with diagnosis, but immunohistochemistry is necessary to distinguish SFTs from other possible diagnoses such as gastrointestinal stromal tumors (GISTs). This study presents a rare case of pelvic SFT initially considered to be a peri-anal GIST, highlighting the importance of accurate diagnosis given the rarity of SFTs and the need to rule out other potential diagnoses.

Unmasking the Uncommon: A Case Report of Scrotal Epidermoid Cysts in a Nine-Year-Old Boy.

Scrotal epidermoid cysts are rare. Intratesticular epidermoid cysts are more common than extra scrotal cysts and are the most commonest benign tumors of the testicles. Midline scrotal raphe cysts are reported, but only a few have intrapelvic extensions deep into the pelvis. A nine-year-old boy presented with a painless scrotal swelling. Magnetic resonance imaging (MRI) of the pelvis confirmed the cystic nature with an extension of the swelling up to the base of the prostate. On surgical exploration, the cyst had a tapering stalk with cranial extension up to the base of the prostate. The patient underwent an excision of the cyst and made an uneventful recovery and was asymptomatic at the end of three months of surgery. The histopathology of the lesion was typical of an epidermoid cyst. Extratesticular scrotal epidermoid cysts with pelvic extension are a rarity with less than five cases reported in the literature. Our case stands to be the youngest reported case of a scrotal epidermoid cyst based on our knowledge. Scrotal epidermoid cysts are a very rare and benign entity, and upon recognition and confirmation of the extent of spread, extratesticular scrotal cysts can safely be removed. No other management may be required with no recurrences reported.

Granulosa cell tumour of the ovary complicated by spontaneous haemoperitoneum in menopause - a case report and systematic review of the literature.

Introduction: A possible cause for acute abdomen is haemoperitoneum resulting from the rupture of an ovarian tumour. Here we discuss a case of spontaneous haemoperitoneum caused by granulosa cell tumour (GCT) rupture in a postmenopausal woman. Material and methods: We present a systematic review of the current literature to draw attention to this rare gynaecological complication and provide guidance about the most appropriate management. Results: Eight case reports and one retrospective study were identified. A total of 11 patients were analysed in this review including the present case report. The first case was described in 1948, while the last one was in 2019. The mean age of the patients was 60.8 years. All cases were treated with primary surgery. The mean diameter of the masses was 10.1 cm. Discussion: We found endometrial pathology in 45% of the cases, of which 4 (36%) were associated with postmenopausal bleeding. The presentation of GCT is not always in the form of overt endocrine disturbance but can onset (10-15%) with acute abdomen. Conclusions: Granulosa cell tumour should remain in the differential diagnosis of all patients presenting with acute abdomen and imaging suspicious for gynaecological malignancy originating from the ovary.

Pelvic leiomyoma associated with intermediate risk prostate cancer: A case report.

Pelvic leiomyoma in male patients is a very rare occurrence and its association with prostate cancer is a unique clinical situation. This study reports a new case of a 9 cm pelvic Leiomyoma associated with intermediate-risk localized prostate cancer in a 68-year-old patient. The leiomyoma was discovered fortuitously after an MRI was performed in the context of prostate cancer work-up. Surgical excision of the pelvic mass along with a radical prostatectomy were performed and the diagnosis of leiomyoma was confirmed by histopathology.

An extremely rare case of an isolated primary benign pelvic Solitary Fibrous Tumor in an elderly female.

INTRODUCTION AND IMPORTANCE: Solitary Fibrous Tumors are highly rare spindle cell tumors of mesenchymal origin. They comprise <2 % of all types of soft tissue tumors and are characterized by an age-adjusted annual incidence rate of 0.61 per 1 million individuals for extra-meningeal Solitary Fibrous Tumors. The disease course is mostly asymptomatic but can still present with non-specific symptoms. This results in misdiagnosis and delayed treatment. In turn, morbidity and mortality rises and it will constitute a clinical and surgical burden for the affected patients. CASE PRESENTATION: We present the case of a 67-year-old female who has a known history of controlled hypertension, who presented to our hospital complaining of non-specific pain in her right flank and lower lumbar region. Our preoperative diagnostic radiological workup demonstrated an isolated antero-sacral mass. CLINICAL DISCUSSION: Comprehensive excision of the mass was laparoscopically achieved. Following the necessary analysis via histopathology and immunohistochemistry, we definitively established the diagnosis of an isolated primary benign Solitary Fibrous Tumor. CONCLUSION: To the best of our knowledge, no previous cases of SFTs from our country were documented. Clinical suspicion and complete surgical resection are vital determinants in treatment of such patients. Further research and documentation are warranted to set-up the necessary guidelines for preoperative assessment, intraoperative techniques, and adequate follow-up protocols to limit the ensuing morbidity and to detect any possible neoplastic recurrence.

Validation of a deep neural network-based algorithm supporting clinical management of adnexal mass.

Background: Conservative management of adnexal mass is warranted when there is imaging-based and clinical evidence of benign characteristics. Malignancy risk is, however, a concern due to the mortality rate of ovarian cancer. Malignancy occurs in 10-15% of adnexal masses that go to surgery, whereas the rate of malignancy is much lower in masses clinically characterized as benign or indeterminate. Additional diagnostic tests could assist conservative management of these patients. Here we report the clinical validation of OvaWatch, a multivariate index assay, with real-world evidence of performance that supports conservative management of adnexal masses. Methods: OvaWatch utilizes a previously characterized neural network-based algorithm combining serum biomarkers and clinical covariates and was used to examine malignancy risk in prospective and retrospective samples of patients with an adnexal mass. Retrospective data sets were assembled from previous studies using patients who had adnexal mass and were scheduled for surgery. The prospective study was a multi-center trial of women with adnexal mass as identified on clinical examination and indeterminate or asymptomatic by imaging. The performance to detect ovarian malignancy was evaluated at a previously validated score threshold. Results: In retrospective, low prevalence (N = 1,453, 1.5% malignancy rate) data from patients that received an independent physician assessment of benign, OvaWatch has a sensitivity of 81.8% [95% confidence interval (CI) 65.1-92.7] for identifying a histologically confirmed malignancy, and a negative predictive value (NPV) of 99.7%. OvaWatch identified 18/22 malignancies missed by physician assessment. A prospective data set had 501 patients where 106 patients with adnexal mass went for surgery. The prevalence was 2% (10 malignancies). The sensitivity of OvaWatch for malignancy was 40% (95% CI: 16.8-68.7%), and the specificity was 87% (95% CI: 83.7-89.7) when patients were included in the analysis who did not go to surgery and were evaluated as benign. The NPV remained 98.6% (95% CI: 97.0-99.4%). An independent analysis set with a high prevalence (45.8%) the NPV value was 87.8% (95% CI: 95% CI: 75.8-94.3%). Conclusion: OvaWatch demonstrated high NPV across diverse data sets and promises utility as an effective diagnostic test supporting management of suspected benign or indeterminate mass to safely decrease or delay unnecessary surgeries.

Metastatic melanoma posing as a pelvic mass.

Pelvic metastasis of melanoma is extremely rare and may pose a diagnostic challenge. We present a case report of a female with a history of colon cancer who underwent exploratory surgery for a pelvic mass that was suspicious for ovarian malignancy. Pathology was consistent with both recurrent colon cancer as well as synchronous newly diagnosed metastatic melanoma.
