This retrospective single-institution study analyzed histologically diagnosed endometriosis cases from the University College Hospital in Ibadan, Nigeria, spanning January 1, 1997 to October 31, 2018, assessing patients’ age and the location and distribution of lesions. Across 85 cases, the mean age was 35 years (range 18–52), with the highest proportions in ages 30–39 and 20–29; the most common lesion site was the ovary (58.8%), followed by the umbilicus (11.9%) and fallopian tubes (9.4%). The study also found bilateral ovarian involvement in 28% of patients and multi-site disease in 21.2%, with left-sided ovarian lesions predominating. This paper is centrally about endometriosis — it characterizes the distribution and features of endometriotic lesions in southwestern Nigeria.

Abstract

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.

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.
