ABSTRACT
Background: This study was done to evaluate the histological types, frequency and age distribution of ovarian tumours in Lagos State University Teaching Hospital (LASUTH), Ikeja, Lagos State. This study also aims to classify ovarian tumours in this centre according to the World Health Organisation (WHO).Methods: A retrospective, descriptive hospital study of all ovarian specimens that were sent to the department of pathology and forensic medicine, LASUTH between 1st January, 2011 and 31st December, 2019 was done. Relevant data composed of the age distributions and histopathological types were extracted from the departmental information system and filed documents. The data was analysed using the IBM-SPSS version 25.0.Results: There were 198 cases of ovarian tumours. The mean age at diagnosis of ovarian tumours was 34.6±15.3 years. Unilateral ovarian tumour was observed in 91.9%% of cases while bilateral disease was seen in 8.1%. Primary ovarian tumours constitute 97.0% of all diagnosed tumours of the ovary. Germ cell tumour was the most frequently diagnosed ovarian tumour; and teratoma was the most common, representing 91.2% of germ cell tumours and 47.0% of all ovarian tumours. Primary ovarian cancer peaked at the 6th decade of life and metastatic ovarian cancer was infrequently seen. Serous carcinoma is the most commonly diagnosed ovarian cancer.Conclusions: Ovarian tumour presents most frequently at the 4th decade of life, and germ cell tumour is the most common.
ABSTRACT
Background: This study was undertaken to evaluate the histological types, frequency, age and sex distribution of bladder carcinoma in Lagos State University Teaching Hospital (LASUTH), Ikeja, Lagos state. This study aims to classify bladder carcinoma in this centre according to the World Health Organisation/ International Society of Urological Pathology.Methods: An eight-year retrospective study of all bladder carcinomas specimens that were sent to the department of Pathology and Forensic Medicine, LASUTH between 1st January, 2011 and 31st December, 2018 was done. Relevant data consisting of the age and sex distributions as well as histopathological types were extracted from the departmental information system and filed documents. The data was analysed using the IBM-SPSS version 25.0.Results: There were 87 cases of bladder tumours, out of which 55 (63.2%) were bladder carcinomas. The mean age at diagnosis of bladder carcinomas was 56.9±13.9 years. Sex distribution has male to female ratio of 1: 1. Urothelial carcinoma predominates as the most common histological type.Conclusions: Bladder carcinoma presents most frequently at the 5th decade of life, with a slight male preponderance.
