Item Neoplasms of the appendix: an experience of a tertiary hospital in Southwestern Nigeria(Faculty of Clinical Sciences, College of Medicine, University of Lagos, Nigeria, 2020) Ajani, M. A.; Omenai, S. A.; Iyapo, O.Background: The appendix is a vestigial tube like organ. Its exact physiological function is unknown. Appendectomies are done usually following a clinical diagnosis of acute appendicitis. Neoplasms can arise from this organ as well. Carcinoids are the most common neoplasms arising commonly at the tips. This retrospective review of neoplasms of the appendix was aimed at identifying the incidence and describing the histological variants of neoplasms of the appendix in our environment. Materials and Methods: This study was a 10 year retrospective review of all appendectomy specimens submitted to the Department of Pathology, University College Hospital, Ibadan, Nigeria, from January 1, 2009, to December 31, 2018. Microscopy was done examining the longitudinal sections from the tip to the base of the appendix. The histological diagnosis was extracted from the records in the department and classified using the WHO classification of tumors of the appendix (2019). Patients’ biodata such as age and sex were also extracted. The data were analyzed for frequency distribution using SPSS 23. Results: The incidence of neoplasms in the appendix was 0.84% of the 1071 appendectomies received in our department over the study period. Low grade appendiceal mucinous neoplasm (LAMN) was the most common histological variant accounting for 55.5% of neoplasms, followed by metastatic carcinoma at 22.2% and carcinoids at 11.1%. There was a female preponderance of 77.8%. Conclusion: Neoplasms of the appendix are rare in our environment, and LAMN was the most common neoplasm of the appendix in our institution. There is a female preponderance among patients with appendiceal neoplasms.Item Morphological Pattern of Endometrial Biopsies In South Western Nigeria.(Association of Resident Doctors, University College Hospital, 2016) Abdullahi, Y. M.; Ajani, M. A.; Iyapo, O.; Aramide, K. O.; Okolo, C. A.; Akang, E. E.Background: Endometrium remains the most sensitive indicator of ovarian function and endometrial biopsy is one of the diagnostic procedures in endometrial pathology. The current study was carried out to examine the morphological pattern of endometrial biopsies in Ibadan, South-western Nigeria and compare the results with similar studies. Method: A retrospective study was undertaken to review all cases of endometrial biopsies received in the Department of Pathology, University College Hospital, Ibadan between January 1999 and December 2008. The patients’ data were retrieved from the surgical pathology daybooks and Histology Request forms. The neoplastic lesions were classified according to 2003 World Health Organization classification for endometrial neoplasms. Results: A total of 2,444 cases of endometrial biopsies were received during the 10-year study period. The functional endometrial changes were the most common histopathological diagnostic category, accounting for 53.8% (1035) of cases. Other pathological diagnoses included endometritis (7.8%), simple endometrial hyperplasia (5.8%), partial hydatidiform mole (2.3%), complete hydatidiform mole (2.1%) and malignant neoplastic lesions (3.9%). Infertility was the most common (57%) indication for endometrial biopsies followed by uterine bleeding (33%) while the least common clinical indication were the menstrual disorders (10%). Conclusion: The functional endometrial changes account for the highest morphological patterns while malignant lesions account for the least pattern of the endometrial biopsies evaluated for etiological basis of infertility, uterine bleeding and menstrual disorders in Ibadan. Infertility was the commonest indication for endometrial biopsies while the least common clinical indication was menstrual disorders.
