Abstrakt:	Background: Keloids are chronic dermal fibro-proliferative disorders resulting from excessive collagen deposition. Although it is commonly seen in the dark skin, it occurs in other races. It is a disfiguring dermatosis whose epidemiology and clinical pattern should be put into proper perspective in an area where it has not been extensively documented. Subjects and Method: A cross-sectional design that included 120 consenting keloids patients was made at the dermatology and plastic surgery clinics of a tertiary hospital over one year. Keloid was diagnosed clinically, risk factors, locations and patterns of affectation were documented. Results: 120 patients with 192 keloids were seen. The mean age of the patients was 36.3±16.0 years with a slight female preponderance (M: F, 1:1.9). The chest was the commonest site 37 (19.3%), then earlobe 27 (14.1%) and face 21(11.0%). The buttock/feet were the least affected areas. Trauma including ear piercing, shaving, lacerations/cuts were the commonest risk factors 108 (56.2%) for keloid. The commonest observed morphological patterns in descending order of occurrence include flat 61 (31.8%), nodular 54 (28.1%) and superficial spreading 51 (26.6%) type. Flat pattern was commonest in breast and chest areas 35 (71.4%), nodular pattern on earlobes 17 (63.0%), face 11 (52.3%), scalp 3 (50.0%), neck 5 (38.5%), and guttate pattern on the face 3 (14.0%) and back 2 (22.0%). The shoulder 5 (50.0%), arms 7 (58.3%) and back 4 (44.4%) had more of the superficial spreading pattern when the morphology/patterns of keloid in these areas were compared. Conclusion: Keloids affects predominantly young adults with single anatomical site being the commonest presentation, with the chest mostly affected and the flat pattern commonly observed. The morphological distinction of keloids and location may influence the choice of treatment modality. Competing Interests: The Authors declare that no competing interest exists.
