“…However unlike a study in Ibadan, Nigeria in which 34.5% of germ cell tumours in children up to 14 years were malignant, in this study, only 23.1% of germ cell tumours in this age group were malignant. Instead, 76.9% of malignant germ cell tumours occurred in the 15–24years age range, older than the age group of the subjects in the Ibadan study [8]. The sample size in this study was however larger than the Ibadan study.…”

BackgroundOvarian tumours are a leading cause of death in Ghana. Even though geographical and racial differences exist in the frequency, types and age distribution of primary ovarian tumours, information about the clinical and pathological characteristics of ovarian tumours in Ghana and its neighboring countries is scanty. We determined the frequency, age distribution, histopathological types and clinical features of primary ovarian tumours diagnosed at the Korle-Bu Teaching Hospital in Ghana to aid in the management of patients.MethodAll pathology records of ovarian tumours diagnosed from January 2001 to December 2010 were reviewed. Histopathologically, tumours were classified according to the then World Health Organization 1999 classification. Biographical and clinical data of patients were also collected and entered into Epi-info to determine the frequency, age distribution and other clinical features of the types of ovarian tumour.ResultsSeven hundred and six ovarian tumours were studied. Germ cell tumours were the most common (41.9%), with mean age of occurrence being 30.7 years (SD 12.7), they were dominated by mature teratomas (39.2%). Surface epithelial tumours were second, and commonly occurred in women aged 35–44years, 77 (26.8%). Sex cord stromal tumours followed with mean age of occurrence of 40.2 years (SD 17.9). The most common malignant tumours were surface epithelial (52.1%) dominated by serous carcinomas with mean age 50.1 years. Most patients (47.7%) presented within 1 month of onset of symptoms, feeling a lower abdominal mass (38.5%).ConclusionThe most common primary ovarian tumours in this study are Germ cell tumours, dominated by mature teratomas. Adenocarcinomas are mostly serous and occur in younger women compared to findings of other Western studies. The single most common malignant ovarian tumour in children and adolescents is Burkitt lymphoma. Patients who develop ovarian tumours have no specific symptoms or signs at presentation, to aid early diagnosis.

“…While some studies report serous cystadenocarcinoma as the commonest malignant tumour others report granulosa cell tumours as the commonest. However in all these studies their sample size was less than 500 cases [6–8]. Again certain tumours are known to be endemic in certain regions, Burkitt lymphoma being an example.…”

“…[ 19 20 ] In Benin City, Nigeria, the granulosa cell tumour was the most common malignant form of ovarian tumour. [ 21 ] Among the gynecological malignancies, ovarian cancer is the deadliest, because of the inaccessible location of the ovary and the absence of standard methods of screening for ovarian cancer. Patients thus tend to present in advanced stages of the disease.…”

Background:The pattern of gynecological malignancies varies among nations and even within health institution in the same country. Understanding the histo-pathological pattern of these malignancies will help in the management of the patient.Aim:The aim of the following study is to establish the frequency, histo-pathological features, and distribution of genital tract malignancies as seen in a tertiary health institution in North - western Nigeria.Materials and Methods:A retrospective analysis of data from ward admissions and discharge records, surgical biopsy materials from the theater and the histopathology laboratory results of slides. The study was carried out at the Usmanu Dan-Fodiyo University Teaching Hospital Sokoto, Nigeria. Data were entered into a study proforma and analysis was through SPSS version 15 (Chicago IL) for windows. The results were expressed in simple percentages, tables and charts.Results:During the study period (2000-2009), there were 404 cases of gynecological malignancies recorded in the hospital. Cervical cancer was the most common gynecological malignancy 274/404 (69%), followed by choriocarcinoma 52/404 (13.1%), ovarian cancer 46/404 (11.4%) while the least common was vaginal cancer 1/404 (0.3%). The mean age of the cancers was 54 years (28.3). The mean age of incidence of all ovarian cancers was 52.5 years (SD ± 16.2). Epithelial ovarian tumors had a mean age incidence of 67 (12) years, while that of ovarian germ cell tumors was 18.5 (8) years. The incidence of cervical cancer showed a rising trend. Moderately differentiated squamous cell carcinoma was the most common histological variant of cervical carcinoma 170/252 (67.5%). Among the ovarian tumors, epithelial cancers were the most common 38/46 (82.6%), and were followed by the germ cell tumors 5/46 (10.9%). Dysgerminoma was the predominant ovarian germ cell tumour 4/5 (80%). There were 50 deaths from these cancers in our hospital.Conclusion:Cervical cancer is the most common gynecological malignancy in our centerand it was followed by Choriocarcinoma. Efforts to reduce the cancer burden should focus on heath education of the masses, national organized screening especially for cervical cancer and establishing regional centers for monitoring and evaluation of these programs.
