Objectives: To determine the relative frequencies, types, subtypes and age distribution of Benign ovarian tumours and to compare the results with other local and international studies. Methodology: A 10 year retrospective analysis of Benign ovarian tumours diagnosed in the Anatomical Pathology Department of University of Port Harcourt Teaching Hospital from January 1998 to December 2007. Results: Out of a total of 7529 surgical specimens received in the department within the study period, 166 (2.2%) were ovarian tumours. Of these 166 ovarian tumours, 128 (77.1%) were benign neoplasms. These 128 benign ovarian tumours formed 1.7% of the total surgical specimen received. The most common histological group was the germ cell tumours (67.2%), followed by surface epithelial tumours (25.8%) and sex cord-stromal tumours (7%). All the germ cell tumours seen were benign cystic teratoma, 86 (67.2%). The lowest age at which benign ovarian tumours occurred in this study was__ampersandsignnbsp; 4years while the highest age was 82years. Benign ovarian tumours peaked in the 21 __ampersandsignndash; 30 years age range, followed by 31- 40 years age range. Conclusion: Ovarian tumours are more commonly benign in our environment with germ cell tumours being the most common histologic group unlike in Caucasians where surface epithelial tumours are more predominant. Benign cystic teratoma is very common in our locale unlike in Europe, North America and some parts of Asia where surface epithelial tumours are more common.
