    (African Journals OnLine, 2019) Ajani, M. A.; Salami, A.; Nwanji, I. D.; Olusanya, A. A.; Fatunla, O. E.
    Background: Endometriosis poses a significant burden mainly to women of child bearing age. Historically, endometriosis was thought to be of low prevalence among African women. However, recent studies have documented an increased prevalence than previously thought. This study aimed to determine the distribution and characteristics of endometriotic lesions among Nigerian women. Methods: A retrospective study of all histologically diagnosed cases of endometriosis from the records of the Department of Pathology, University College Hospital, Ibadan from 1st January, 1997 to 31st October, 2018.The age of the women, location and distribution of the lesions were analysed. Results: A total of 85 cases of endometriosis were diagnosed histologically in the period under review. The mean age was 35 years with an age range of 18 to 52 years. The most commonly affected age groups were those between 30-39 years (47.1%) and 20-29 years (30.6%). The most commonly affected site was the ovary (58.8%) followed by the umbilicus (11.9%) and fallopian tubes (9.4%). Fourteen patients (28%) had bilateral ovarian involvement. Left sided ovarian lesions predominated (61.1% versus 38.9%). Eighteen (21.2%) patients had lesions at more than one site frequently involving both ovaries. Conclusion: Endometriosis affected mainly women of childbearing age with particular predilection for the ovaries. Endometriosis affecting the umbilicus is not uncommon among Nigerian women.

    Histopathological pattern of primary ovarian neoplasms in South Western Nigeria.
    (Association of Resident Doctors of Jos University Teaching HospitalAssociation of Resident Doctors of Jos University Teaching Hospital, 2016) Ajani, M. A.; Aramide, K. O.; Salami, A.; Okolo, C. A.
    Background: Ovarian tumours are common form s o f neoplasms in women. This study aims to determine the histopathological pattern o f primary ovarian neoplasms in South-western Nigeria. Method: A retrospective study was undertaken to review the histopathology reports o f all primary ovarian neoplasm specimens submitted to the Department o f Pathology, University College Hospital, Ibadan from January 1991 to June 2013. Patients'biodata were extractedfrom the requestforms and surgical day books. Results: There were 821 cases o f primary ovarian neoplasms. 359 (43.7%) cases were surface epithelial neoplasms which were found in patients with age range 10-89 years. Three hundred and thirteen (38%) cases o f germ cell tumour were found in patients with age range 0-70 years. One hundred andforty-six (17.8%) cases ofsex cord stromal tumour werefound in patients with age range 0-99 years. Mature Cystic Teratoma was the most common (54.7%) among benign ovarian neoplasms with 20-29 years being the age range with highest tumours while serous cystadenocarcinoma was the most common (33.2%) primary malignant ovarian neoplasms with 50-59years being the age range with highest tumours. Conclusion: Surface epithelial tumours were the most common ovarian neoplasmfollowed by germ cell tumours. This pattern is observed in most parts of Nigeria, some African and Asian countries, and in the Western world.

    Childhood ovarian neoplasms in Ibadan, South‑western Nigeria.
    (Wolters Kluwer - Medknow, 2016) Ajani, M. A.; Aramide, K. O.; Ajani, T. A.; Salami, A. A.; Okolo, C. A.
    Childhood ovarian neoplasms are very rare. Little information is available on the relative pattern and frequency of these tumors in Nigerian children. Earlier study done in Ibadan involved ovarian neoplasms in children and adolescents. The aim of this study is to review cases of ovarian neoplasms in childrenMaterials and Methods: This was a retrospective study. Twenty four cases of childhood ovarian neoplasms were seen in patientsResults: Childhood ovarian neoplasms accounted for 2.8% of all cases of ovarian tumors seen in this period. Fourteen (58.3%) cases of childhood ovarian neoplasms were benign, and 10 (41.7%) were malignant. Mature cystic teratoma occurring in 13 (54.2%) was the most common childhood ovarian neoplasm and was most prevalent between 10 and 14 years of age. Burkitt lymphoma was the most common 4 (40%) malignant childhood ovarian tumor and prevalent between 5 and 14 years of age. Conclusion: Mature cystic teratoma remains the single most common childhood ovarian neoplasms, and Burkitt’s lymphoma is the most malignant childhood ovarian tumor in Ibadan, South western Nigeria.
