OBJECTIVE: A histopathologic analysis of epidermal skin tumours and tumour-like lesions seen between 1991 - 2000 in the Department of Pathology, Ahmadu Bello University Teaching Hospital [A.B.U.T.H], Zaria is presented. PATIENTS AND METHOD: These tumours were classified according to World Health Organisation's International Histological Classification for Skin Tumours and were tabulated. RESULTS: A total of 350 such lesions comprising 9.9% of all cutaneous neoplasms seen within the study period were collected. Overall, they have a male to female ratio of 1.7:1. Malignant tumours constituted 72.5%; benign tumours 18.3% and tumour-like lesions 9.2%. The commonest malignant lesion was squamous cell carcinoma, which constituted 68.3% of all the lesions with a male to female ratio of 1.7:1. Epidermal cyst comprised 16.3% with a male to female ratio of 1.5:1. CONCLUSION: It is concluded that epidermal tumours and tumour-like lesions are not uncommon in Zaria and they show a male preponderance with squamous cell carcinoma being the commonest epidermal tumour and it also predominantly affects males.
