A Clinico-Pathological Study of Vulvo-Vaginal Disease at a Nigerian Tertiary Health Facility.

INTRODUCTION: The vulva and vagina are of great significance to womanhood owing to the myriads of specialized functions they perform. The diseases of this organ have physical, social, mental, and psychological ramifications. The aim of this work is to study the pathological pattern and clinical presentation of diseases of the vulva and vagina at the Department of Anatomical Pathology and Forensic Medicine of the Jos University Teaching Hospital between 1st January 2011 and December 31st, 2020. METHODOLOGY: This study is descriptive of all cases of histologically diagnosed vulval and vaginal lesions seen at the Center. Histological diagnosis, biodata, and clinical information of patients were retrieved from the medical records. Data realized were analyzed and presented in tables as simple frequencies, percentages, ranges, and measures of central tendencies. RESULTS: Two hundred and fifteen vulval and vaginal biopsies were included in the study. Squamous cell carcinoma was the commonest histologically diagnosed lesion accounting for 70(32.6%) cases of all lesions and 77.8% of all malignancies. The second commonest lesion and the most frequent benign pathology is the Condyloma acuminatum (viral warts) which accounted for 41(19.1%) cases. The age bracket 20 to 59 years constituted 79.5% of cases (171 cases). The age range, mean, median, and mode in years were 5.0-85.0, 39.5+15.9, 38.0, and 50.0 respectively. CONCLUSION: Squamous cell carcinoma and veneral warts are the commonest lesions of the vulva and vagina in our environment. Robust vaccination programs against the etiological agent, the human papilloma virus is highly recommended.

Sarcomas in Nigerian Children in Jos North Central Nigeria.

BACKGROUND: There is a growing concern about childhood sarcomas, with recent studies suggesting an increase in the frequency of childhood sarcomas in sub-Saharan Africa. This study was carried out to determine the pattern of childhood sarcomas in Jos, North Central Nigeria and to compare the data obtained with other previous related studies. METHODS: Review of the Jos University Teaching Hospital cancer registry from January 2001 to December 2010. Data of all children (0-15 years) in the data base were retrieved for analysis. RESULTS: Two hundred and ten histological diagnosis of malignancies were made in children over the period, with 81 cases (39%) being childhood Sarcomas. The sarcomas occurred predominantly in males (54%) with male/female ratio of 2:1. The minimum age was 2 months and the maximum age was 15 years. Soft tissue sarcoma (STS) was the most predominant group which accounted for 73 cases (90%) of all sarcomas seen. Rhabdomyosarcoma (RMS) was the most common STS, it accounted for 65 cases (89%) of the STS and 80% of all the sarcomas. This is followed by Kaposi Sarcoma (KS) accounting for 6.9% of STS. There were 8 cases of Osteosarcoma which accounted for 10% of all the sarcomas. Embryonal RMS predominated in the very young children while all other sarcomas affected the older children. Extremities were the sites of predilection for most of the sarcomas (36%). Seventeen (17) cases of the RMS were of superior prognostic group, 34 (54%) were of intermediate prognostic group while 24 cases (37%) were of poor prognostic group. CONCLUSION: Childhood sarcomas are common in our environment and RMS is the single most common sarcoma while the non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) are rare.

Role of parasites in cancer.

BACKGROUND: In areas of parasitic endemicity, the occurrence of cancer that is not frequent may be linked with parasitic infection. Epidemiological correlates between some parasitic infections and cancer is strong, suggesting a strong aetiological association. The common parasites associated with human cancers are schistosomiasis, malaria, liver flukes (Clonorchis sinenses, Opistorchis viverrini). OBJECTIVE: To review the pathology, literature and methods of diagnosis. METHOD: Literature review from peer reviewed Journals cited in PubMed and local journals. CONCLUSION: Parasites may serve as promoters of cancer in endemic areas of infection.

Histopathological analysis of endometrial biopsies in Jos University Teaching Hospital (JUTH), Nigeria. A 5-year critical review.

AIMS: This study is aimed at giving an insight into the pattern and age distribution of endometrial analysis as seen at Jos University Teaching Hospital. METHODS: This is a retrospective reviewed cases of endometrial biopsies diagnosed between January 1998 to December 2002 in the Histopathological Department ofJos University Teaching Hospital RESULTS: A review of endometrial biopsies slides from 556 patients revealed that pregnancy related diagnosis was the commonest, representing 302 (54.3%) of histopathological diagnosis, followed by endometrial hyperplasia, accounting for 97 cases (17.5%) and majority of which was categorised as mild hyperplasias. Hydatidiform mole, which ranked third, constituted 58 (10.4%) of the cases studied. Choriocarcinoma was the leading malignancy representing 10 cases (45%) of the malignant tumours and 1.8% of all the endometrial biopsies. Endometrial adenocarcinoma, stromal sarcoma and metastatic cancer constituted 6 (1.0%), 3 (0.5%) and 3 (0.5%), respectively. CONCLUSION: The commonest endometrial pattern seen in JUTH over the study period was products of conception which peak in the third decade of life; primary malignancies of the endometrium are uncommon in JUTH and they represented just about 2%.

Childhood rhabdomyosarcoma: a review of 35 cases and literature.

UNLABELLED: BCKGROUND: Rhabdomyosarcoma is one of the most frequent soft tissue sarcomas in children. It constitutes a unique group of soft tissue sarcomas found in children, primarily infants, toddlers and preschool pupils. OBJECTIVE: The purpose of this review is to examine all the cases of histologically confirmed childhood rhabdomyosarcomas; to re-examine the review pattern, and review recent advances in the biology of this neoplasm. MATERIALS AND METHODS: the sample consisted of 35 histologically confirmed rhabdomyosarcomas between January, 1996 and 2005. The specimens consisted of excision, incision and tru-cut biopsies. Fresh sections were cut from paraffin bedded tissue blocks and stained with haematoxylin and eosin. The slides were reviewed by three pathologists. The sites of biopsies were noted from the referral forms. RESULTS: Thirty five cases of paediatric rhabdomyosarcomas were recorded out of a total of 55 cases during the period of study. This represents 63.6% of all cases of rhabdomyosarcomas. The commonest anatomical sites were head and neck regions which accounted for 21 cases of the 35, while retroperitoneal, vagina and testis accounted for 8, 3 and 3 respectively. The highest proportion of cases occurred in ages 6-15 years. The embryonal subtype accounted for highest proportion, followed by alveolar, pleomorphic and spindle types respectively. CONCLUSION: This study shows that childhood rhabdomyosarcomas are prevalent in this region, and that the most prevalent of the variants is embryonal rhabdomyosarcoma. The commonest anatomical sites were head and neck regions and the highest proportion of cases occurred in ages 6-15 years.

Epidemiology of gastric cancer in Jos University Teaching Hospital Jos a 20 year review of cases.

BACKGROUND: Gastric cancer believed to be rare in the past in Africa, is now one of the leading cancer morbidity and mortality. It is now known gastric cancer is 2-3 times higher in males than females living in the same environment. We aim to describe the comprehensive histological characteristics of gastric cancer with age and sex distribution. METHODS: The study site was Jos University Teaching Hospital situated in the capital of Plateau State. The hospital has a bed capacity of 530. The study materials were obtained from all stained specimens of gastric cancer recorded in the histopathology laboratory of the teaching hospital between 1985 to 2004. The biopsy site was noted. These were divided into the following groups: Cardia, body and an thrum/pyloric regions respectively. Or the information included age and sex of the patients. RESULTS: There were a total of 205 gastric cancer histological confirmed, out of 5705 malignant tumours recorded in the same period. There were a total of 145 cases in male and 60 in females giving a male: female ratio 2.4:1. The highest frequencies of gastric cancers were located in the anthral and cardia regions which accounted for 79% of all the tumours. Well differentiated adenocarcinoma (intestinal type) was the most frequent histological subtypes 51.2%), this was followed by poorly and diffusely infiltrating carcinoma. Other cancers included signet ring carcinoma, Non-Hodgkin's lymphoma and leiomyosarcoma in that order. The study has also demonstrated H pylori at the background of intestinal type adenocarcinoma which was seen in the body and an thrum. CONCLUSION: The study has shown that gastric cancer is not only common but it occur more males than females. The high proportion of H pylori in our environment might indicate a possible aetiological association. Therefore eradication of H pylori might reduce the prevalence of gastric carcinoma.

Diagnostic oncology: role of the pathologist in surgical oncology--a review article.

The practice of surgical oncology requires a multidisciplinary approach involving the pathologist, surgeon, clinicians and other workers. The task of a pathologist is to provide adequate, and accurate diagnosis sufficient for the clinician to take decision for patient management. In the tropics, the practice of pathology is seriously challenged by infrastructural decay and in most cases clinicians rely on their clinical skills for management of cancer patients. With tremendous advance in the field of oncology, the diagnosis of cancers involve the understanding of biological behaviour of the cancer. The details of type and origin of the tumour, its differentiation, level of invasion, the number of lymph node(s) with and without metastasis, the presence or absence of receptors for hormones, activity of enzymes, ploidy, frequency of mitosis and percentage of cells in the S-phase may all be relevant in the pathological assessment of neoplastic tissue. The use of molecular biology has also enhanced our understanding of the neoplastic process. Examples include the use of nucleic acid probes with or without amplification, polymerase chain reaction to detect expression of specific tumour genes or gene mutations, but these have not yet become standard practice in this environment. The review is aimed at highlighting the role of the pathologist in the management of cancer.

Patterns of malignant salivary gland tumours in Jos University Teaching Hospital (JUTH), Jos: a ten-year retrospective study.

BACKGROUND: Salivary gland tumours are common head and neck tumours and more common in western world than Africans. Most salivary gland tumours are benign but the morbidity and mortality as expected is higher with malignant tumours. This study is aimed at describing the histological pattern, age, sex and site distribution of malignant salivary gland tumours in Jos University Teaching Hospital (JUTH) Jos from January 1998 to December 2007. METHODS: This is a descriptive study of all histologically confirmed malignant salivary gland tumours over a period of ten years. Fresh sections of tissue blocks of these lesions were made using the microtome (3 micrones). They were made into slides and stained with Hematoxylin and Eosin (H and E) and Periodic Acid Schiff (PAS) stains. The slides were reported independently by four pathologists. Diagnosis was made and classification done according to the World Health Organisation (WHO) classification of salivary gland tumours 3. Information such as age, sex and-site of distribution of these tumours was gotten from the patient's case files. The data was analyzed manually. RESULTS: Muco-epidermoid carcinoma accounted for the highest (32 cases) histologic type. Malignant salivary gland tumours occurred more within the age range 40 to 69 years with the age group 50-59 years accounting for the highest frequency (36 cases). Most of these malignant salivary gland tumours occurred more in the parotid gland, the minor salivary being the least site of occurrence. CONCLUSION: Mucoeperdermiod carcinoma is the commonest salivary gland tumour and that malignant salivary gland tumours in this study and it occurred more after the 5th decade of life.

Hepatocellular carcinoma in Jos, Nigeria.

BACKGROUND: Hepatocellular carcinoma (HCC) is the most common abdominal malignancy, representing 80-90% of primary liver malignancies around the world. There is a disturbing trend of increased incidence of HCC around the world. We therefore, determined the trend of HCC in Jos. METHODS: A ten-year retrospective review was done of all cases of HCC which diagnoses were histologically confirmed as recorded in the Cancer Registry of Jos University Teaching Hospital. The patients' clinical case notes (including surgical and radiological findings) were also reviewed. RESULTS: A total of 71 cases of HCC (31.3% of 227 liver biopsies in the same period) were diagnosed within the 10-year period. There were 46 males and 25 females with a male/female ratio of 1.8:1. The age range of the patients was 23 years to 75 years, with a mean age of 45.4 +/- 13.1 years. Seventy two percent (72%) of them were between ages 21 years and 50 years. Only 28% were between 51 years and 80 years. The highest rate of 12 (17.1%) was seen in the year 2004. CONCLUSION: The study showed that there was a high prevalence of HCC in Jos, and that HCC was more prevalent in the younger age group compared to what obtains in developed nations.

Relation between Helicobacter pylori, inflammatory (neutrophil) activity, chronic gastritis, gastric atrophy and intestinal metaplasia.

BACKGROUND: To determine the relation of Helicobacter pylori infection with chronic inflammation, atrophy, activity level and intestinal metaplasia. PATIENTS AND METHODS: A cross-sectional study of 100 consecutive patients with dyspepsia. These patients were fasted for 12 hours and gastroscopic biopsy specimens were obtained from their gastric mucosae. The specimens were histologically evaluated for H. pylori, inflammatory activity, chronic inflammation, gastric atrophy and intestinal metaplasia. RESULTS: There were 50 (50%) females and 50 (50%) males. The average ages of women and men were 36.3 +/- 11.5 and 42.9 +/- 12.8 respectively. Helicobacter pylori was found in 79%. Neutrophil activity was observed in 83%. Inflammation was found in 95%, glandular atrophy in 38%, intestinal metaplasia in 28% of the cases. Incidental (early gastric) cancer was found in 3%, dysplasia in 2% and reactive gastropathy in 7% of the cases. A statistically significant relationship was found between Helicobacter pylori colonization intensity and the degrees ofneutrophil activity, chronic inflammation and intestinal metaplasia. CONCLUSION: We concluded that Helicobacter pylori infection results in neutrophil activation and chronic gastritis, and that it has a role in the development of intestinal metaplasia. The greater the intensity of Helicobacter pylori infection, the greater the degrees of neutrophil activation, chronic gastritis and intestinal metaplasia.

Epidemiology of soft tissue sarcomas in Jos, North Central Nigeria.

BACKGROUND: Soft tissue sarcomas are a complex heterogeneous group of tumours that often cause a diagnostic problem. Special stains are often employed for further differentiation of these tumours. As a group, soft tissue sarcomas are not uncommon as previously believed. OBJECTIVE: To undertake a ten year retrospective study of soft tissue sarcomas in a Nigerian Teaching Hospital and to also discuss the pathology of the disease. METHODS: The study consisted of all records of histologically confirmed cases of soft tissue sarcomas from 1994 2003, seen at JUTH. The slides were retrieved and read separately by two pathologists. Special stain such as Reticulin, PTAH, Oilred O, were used to demonstrate basement membrane, muscle striation and lipids respectively. These aided confirmation of the diagnosis. Information extracted from patients' records included age, site of lesion and sex. RESULTS: A total number of 266 cases of soft tissue sarcomas were recorded out of 2353 histologically confirmed cancers. These accounted for 11.3% of all cancers. One hundred and eighty three occurred in males and 83 in females, with male, female ratio of 2:1. Kaposi sarcoma (KS), Rhabdomyosarcoma (RMS), Malignant Fibrous Histiocytoma (MFH), and Fibrosarcoma (FS) were the commonest histological subtypes accounting for 69 (25.9%), 63 (23.7%), 56 (21.1%) and 49 (18.4%) respectively; with Rhabdomyosarcoma occurring more in paediatric and adolescent age groups, while the rest subtypes were more prevalent in adults. The commonest sites affected were leg/foot 71 (26.7%), head/neck 68 (25.6%) and thigh 50 (19%). CONCLUSION: Soft tissue sarcomas constituted a significant proportion of cancers in our centre and are not uncommon as previously reported in the literature.

Hepatitis B surface antigen, hepatitis C and HIV antibodies in a low-risk blood donor group, Nigeria.

We investigated the seroprevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) infection among 258 clergymen-in-training (age range 18-39 years) who represented a donor population that fulfilled the criteria for safe blood transfusion. In all, 15.1% of the men were positive for HBsAg, 4.3% were positive for anti-HCV and 2.7% were HIV-positive; 22.1% were infected with at least one of these viruses. Co-infection with HIV and HBV was found in 0.4% of the subjects, HBV and HCV in 0.4%, and HIV and HCV in 0%. This underscores the importance of routine screening of blood before transfusion, regardless of the donor background.

Gastric histopathological findings in mucosal biopsies of symptomatic patients in jos central Nigeria.

BACKGROUND: Dyspepsia is a common disease worldwide. It is a cause of great absenteeism from work with a lot of economic loss. In Jos, it is one of the most common complaints encountered in both general outpatient and specialist clinics. AIM: To evaluate the histopathological changes in gastric mucosa of patients presenting with symptoms of dyspepsia. METHODS: Cross sectional study. Gastric endoscopic biopsy specimens from 100 consecutive patients with symptoms of dyspepsia were histologically evaluated using the criteria of the updated Sydney system. RESULTS: There were 50 males and 50 females. Their overall mean age was 39.6 +/- 12.2 (S.D). The prevalence of Helicobacter pylori colonization was 79%. Males were 53.2% and females 46.8% respectively giving a sex ratio of 1.4:1. Gastritis, neutrophil activity, glandular atrophy and intestinal metaplasia were observed in 95%, 83%, 38% and 28% respectively. Gastric carcinoma was found in 3% ofthe patients. CONCLUSION: From our study, we conclude that the majority of our patients with dyspeptic symptoms have significant histopathological changes in their gastric mucosa with implications for the development of further gastric lesions, and that the most common cause of dyspepsia in our environment is Helicobacter pylori infection.

Primary head and neck cancers in Jos, Nigeria: a re-visit.

BACKGROUND: To document the pattern of primary head and neck cancers in Jos, Nigeria. STUDY DESIGN: A record-based study of head and neck cancers histologically diagnosed at the Jos University Teaching Hospital (JUTH), Jos, between January 1987 and December 2002. RESULTS: A total of 710 cases (over 44 cases per year) were diagnosed, with a rising trend. The most common sites for cancer were the eyes (15.4%), lymph nodes (12.4 %), thyroid gland (11.8%) and the oral cavity (7.6%). Carcinomas 432(60.8%), lymphomas 119(16.8%) and sarcomas 105(14.8%) were the commonly reported cancers. Carcinomas were most commonly reported in the thyroid gland (19.2%), oral cavity (10.2%) and the eyes (9.5%). AIDS-related cancers constituted 12.3% of all head and neck cancers and were commonly reported in the 3rd decade of life. This is higher than the 10.9% and 7.6% previously reported for Jos (p=0.89) and Maiduguri (p=0.034) respectively. Carcinomas were associated with alcohol use and tobacco smoking (p<0.001), while kaposi sarcoma was more associated with HIV-positive patients than squamous cell carcinoma (p=0.016). The duration of symptoms for cancers varied with sites and cancer type but ranged from 6.5-89.7 months (mean= 37.7 +/- 51.1 months). 59 (93.7%) of the staged cancers reported in the late stages (III & IV). 48 (43.2%) of the treated cancers had primary surgery, while most lymphomas were treated with primary chemotherapy. CONCLUSION: There is a rising trend in the occurrence of head and neck cancers in Jos, with a considerable proportion of the patients being below 30 years. The late presentation of patients, late stage at presentation, the rising profile of HIV/AIDS in the area and the non-availability of relevant specialists in the hospital could adversely affect the prognosis of these cancers.

Medicolegal autopsies in North Central Nigeria.

OBJECTIVE: To determine the pattern and the causes of deaths reported to the coroner for medicolegal autopsies in North Central Nigeria. DESIGN: A descriptive retrospective study. SETTING: Jos University Teaching Hospital, Jos, Nigeria between January 1996 to December 2003. SUBJECTS: Autopsies reports of 279 subjects whose causes of death were subjects of litigation. MAIN OUTCOME MEASURES: The causes of death in medicolegal autopsies. RESULTS: A total of 279 cases of medicolegal autopsies with identified causes of death were recorded representing 89% of all the autopsy examinations performed within the period. In 7.6% of cases, there was no identifiable cause of death. There were 127 males against 52 females with a male: female ratio of 4.5:1 and their ages ranged between two and 74 years with a mean of 34.7+/-8.2 years. Children aged < 15 years made up 29% of the cases and were distributed as follows: 4% of the children were aged 0-5 years, 9% between six to ten years while 17% were between 11 - 15 years. Accidental deaths made up 51% of the cases, homicides 36% and sudden deaths 13%. Road traffic accidents were responsible for 76% of all accidental deaths. Children were affected in 34% of the accidental deaths and half of them were pedestrians at the time of accident. The male: female ratio of deaths from road traffic accidents was 3:1 with mean age of 24 years. In all the accidental deaths, abdominal injuries were responsible for 47% while 30% died from chest injuries. Of the homicide cases male subjects outnumbered female in a ratio of 16:1 and children were affected in 28% of homicides. Injuries sustained during ethnic and religious crisis were responsible for 48% of the deaths from homicide and 15% of them were children. Armed robbery was responsible for 28% cases while physical assaults were responsible for 20% of homicides. Chest injuries were the causes of death in 54% and abdominal injuries in 36% of homicides. Cardiovascular deaths were responsible for 63% cases of all sudden natural deaths referred for Coroner's inquest during the period. Children made up 11% of all sudden natural deaths. Males outnumbered females in cardiovascular deaths in a ratio of 6:1 and 46% cases of them died of hypertensive heart failure, 32% had cerebrovascular accidents, pulmonary embolism in 13.6% and myocardial infarction in 9%. One case of myocardial infarction died during intercourse. CONCLUSION: Road traffic accidents, violent communal unrest and armed robbery were responsible for 66% of the medicolegal autopsies in our environment. Public enlightenment, good road maintenance and safe driving culture as well as sustainable security for life and property would reduce the incidence of preventable deaths.

Clinicopathological features and molecular markers of breast cancer in Jos, Nigeria.

BACKGROUND: Several studies have suggested that breast cancer in black women is associated with aggressive features and poor survival. This study examines molecular markers along with clinical stage and pathological grade in breast cancer material from Jos, Nigeria. STUDY DESIGN: The histological diagnoses of 178 consecutive Nigerian patients with breast cancer were retrieved from their hospital records. A subset of 36 patients was staged and their tumours typed and graded. Immunohistochemical staining of sections from paraffin wax embedded tissues from these cases for the expression of oestrogen receptor (ER), progesterone receptor (PGR), Human ERBB2 (or HER2/neu), p53 and cyclin D1 (CCND1) was carried out using the avidin biotin complex (ABC) procedure. RESULTS: A majority of the cases were invasive ductal carcinoma (92.7%), high grade (grade 3, 70.6%) and of late clinical stage (stages III and IV, 58.3%). Only 25% and 27.8% of cases expressed ER and PGR respectively. The ERBB2 and CCND1 antigens were expressed in 25%, and 5.7% of cases respectively. The p53 protein was the most frequently expressed in this study (47.2% of cases). High grade tumours were significantly more likely to be ER and PGR negative (P = 0.006 and P = 0.002 respectively). CONLCLUSION: There is predominance of high grade, invasive ductal carcinomas which are likely to be ER and PGR negative but p53 positive. These features suggest a biologically aggressive form of breast cancer in Nigerian women with the possibility of poor response to both hormonal therapy and chemotherapy.

Thyroglossal duct lesions in childhood--a review of experience in Nigerian children.

This is a retrospective study of 36 children with thyroglossal duct lesions managed at a tertiary hospital in Nigeria, between 1993 and 2003. The aim was to determine the pattern of presentation and outcome of management. The majority of patients presented with a chronic thyroglossal sinus with associated recurrent inflammation. The location and relationship of the lesions to the hyoid bone were similar to those encountered in the rest of the world. Despite their well-documented clinical features, thyroglossal duct lesions were misdiagnosed in some patients. The main complications were surgical site infections and recurrence. A plea is made for clinicians to pay attention to clinical and operative details so as to diagnose these lesions accurately and manage them properly.

A review of 101 homicide cases in Jos, Nigeria.

A five-year retrospective analysis of 101 homicide cases in Jos, Nigeria was carried out between 1995 and 1999. Of the total number, 47 were killed with sharp cutting or piercing instruments, 28 with firearms and 21 died from physical assaults. Five of the victims sustained fatal burn injuries. Majority of the cases (62.4%) were aged between 21 and 40 years and males outnumbered females by a ratio of 7.4:1. It is concluded that although a significant proportion of homicides are not premeditated, communal violence and robbery attacks remain the most frequent precipitating events that result in homicide in this environment.
