Pattern of Skin Cancers in a Tertiary Medical Center in Southwest Nigeria

Background: Skin cancers are the most common malignancies in the western world, and their incidence is increasing globally. However, the data about the pattern in sub-Saharan Africa are limited. This study evaluates the pattern of primary skin malignancies in a tertiary medical center located in a sub-urban area. Methods: The histo-pathological records of patients managed for malignancies from January 2012 to December 2020 were retrieved from the pathology department of a tertiary medical center in Ekiti State, Southwest Nigeria. All primary skin cancers seen within this study period were extracted from the records and then reviewed retrospectively. Results: The male-to-female ratio of primary skin malignancies was 1:1.06, and the mean age of patients was 57.2 ± 17years. All patients were black Africans who were mainly of the Yoruba ethnicity (97.2%). Squamous cell cancer had the highest frequency (34.7%), followed by melanoma (27.8%), dermatofibrosarcoma (12.5%), and basal cell carcinoma (11.1%). The most commonly affected anatomic region is the lower limbs (50.6%). Conclusion: The pattern of primary skin cancers seen in black Africans differ from that of Caucasians: however, larger community-based studies in our environment is recommended to provide more conclusive information about the pattern of skin cancers.
