Item Histopathological characteristics of gynaecomastia in Southwestern Nigeria: A review from a tertiary hospital(Wolters Kluwer - Medknow, 2020) Ajani, M. A.; Salami, A. A.; Awosusi, B. L.; Omenai, S. A.; Iyapo, O.; Odetola, S. S.Background: Gynaecomastia is a benign proliferation of the glandular tissue of the male breast. It is thought to be present in at least a third of men in the course of their lifetime. This study aims to review the histomorphological characteristics of gynaecomastia seen at the department of Pathology, University College Hospital (UCH), Ibadan, over 10 years period. Methods: A hospital-based retrospective study was undertaken to review the histopathology reports of all gynaecomastia cases diagnosed at the Department of Pathology, UCH Ibadan, over a 10-year period from 01 January, 2009 to 31 December, 2018. Patient’s biodata, histological diagnosis and clinical details were extracted from the surgical day books and laboratory request forms. The data were analysed for the frequency distribution using the SPSS software version 22. Results: Gynaecomastia accounts for 2.5% of all breast biopsies received within the study period and accounted for 68.1% of all benign breast lesions seen in males. The left breast was the most affected with 48.8% of the cases, whereas 17.2% of the cases were bilateral. The age range of patients with gynaecomastia seen in this study is between 12 and 80 years with a mean age of 43.36 years. The most common histopathological subtype seen in this study is the florid type gynaecomastia. Conclusion: Gynaecomastia is the most common diagnosis from male breast biopsies. The left breast is the most commonly affected breast. The florid type gynaecomastia is the main histopathological variant seen in this study.Item Hormonal receptor expression in endometrial carcinoma: a retrospective immunohistochemical study in a Nigerian tertiary hospital(Medknow, 2022) Odetola, S. S.; Ajani, M. A.; Iyapo, O.; Salami, A. A.; Okolo, C. A.Background: Endometrial carcinoma is the commonest genital tract malignancy in most developed nations, but it lags behind cervical carcinoma and ovarian cancers in most developing nations including Nigeria. Estrogen has been described as a promoter of endometrial carcinogenesis. Objectives: The aim of this study was to demonstrate the frequency of estrogen receptor (ER) and progesterone receptor (PR) expressions of endometrial carcinoma and to correlate it with tumour grade. Materials and Methods: Cases of endometrial carcinoma diagnosed in the Department of Pathology over a 10-year period were reviewed retrospectively. The paraffin-embedded blocks were retrieved, and immunohistochemistry for ER and PR was performed on them. Haematoxylin and eosin (H&E) slides were reviewed, and tumours were graded by three independent pathologists. Data were analysed using SPSS version 22. The level of significance was set at P ≤ 0.05. Results: There were 44 cases of endometrial carcinoma. ER and PR were positive in 29.5% and 18.2% of endometrial carcinoma, respectively. There was no significant association between ER (P = 0.361) and PR (P = 0.204) expressions and histological grade of the tumour. The most common histological grade was grade 3 with 70% of cases (36 cases), whereas 13 cases (26%) were grade 2 and only 2 cases (4%) were grade 1. Conclusion: The positive expressions of ER and PR in endometrial carcinoma suggest that steroid receptor studies may be of potential benefit in the management of some patients with endometrial carcinoma. Future studies employing larger sample size are therefore recommended.Item Secondary ovarian neoplasms in a tertiary hospital in South-Western Nigeria(Association of Resident Doctors, University College Hospital, Ibadan, Nigeria, 2019) Ajani, M. A.; Iyapo, O.; Salami, A.; Okolo, C. A.Background: The ovary is a common site of involvement for metastases constituting 5-30% of all malignant ovarian neoplasms. Over half of these tumours are bilateral. The commonest sources are stomach, large bowel, appendix, breast, uterus (corpus and cervix) and lung. Aim: The aim of this study was to determine the histopathological pattern of metastases to the ovary at the University College Hospital, Ibadan, South western Nigeria. Material and Methods: This was a retrospective study. All histologically confirmed cases of metastases to the ovary from the records and files of the Department of Pathology, University College Hospital (UCH), Ibadan between January 1991 and June 2013 were used for the study. These were cases diagnosed following total abdominal hysterectomy, total abdominal hystero-salpingo oophorectomy, bilateral salpingo-oophorectomy, omentectomy, and multiple peritoneal biopsies and post-mortems at the University College Hospital between January 1991 and June 2013. Cases with inadequate clinical data and whose blocks and or slides could not be retrieved were excluded from the study. The data obtained were analysed using the Statistical Package for Social Sciences version 20 Results: There were 46 cases of metastases to the ovary constituting 5.3% of total ovarian neoplasms. Thirty (63.9%) cases were metastatic carcinomas with the affected patients’ age range of 20-79 years, and peak incidence within the age group of 30-39 years. Nineteen out of 30 cases of metastatic carcinomas were from adenocarcinoma of colon, 6 cases were from the gastric carcinoma while the remaining five cases were from the squamous cell carcinoma of the uterine cervix. Fifteen (31.9%) cases of Burkitt Lymphoma were found with patients with age range of 0-39 years, and the peak age of occurrence at the 2nd decade. The only case of metastatic Malignant Mixed Mullerian Tumour and metastatic Leiomyosarcoma were found in the 3rd and 4th decades of life respectively Conclusion: This study has shown that metastases to the ovary occur in younger age groups in our environment. Therefore this study emphasizes that in young females with ovarian masses, the likelihood of metastatic tumours should not be discarded because, correct and precise diagnosis of secondary ovarian malignancy is critical as it has significant implication on the patients’ choice of management and prognosis.
