A 20 year study of skin tumours was undertaken in the Department of Pathology, University College Hospital, Ibadan between 1980 and 1999. A total of 936 patients with confirmed skin tumours were reviewed. The data obtained were analyzed using the SPSS statistical analytic package. The results showed a peak age in the third decade of life for skin tumours and tumour like lesions generally. Sligthly more than half (58.3%)of the skin tumours were benign while malignant tumours accounted for 41.7%. Over half of all benign tumours (58%) occurred in patients less than 30 years, while only 18.6% of malignant neoplasms occurred in patient less than 30 years of age. The head and neck region was the commonest site of occurrence of cutaneous neoplasms followed by the foot, anogenital region and trunk. Epithelial neoplasms were the most common (39.4%) followed by soft tissue neoplasms (35.5%), skin adnexal tumours (8.9%), lymphoreticular neoplasms (1.6%) and metastatic skin tumours (2.4%). Squamous cell carcinoma was the most common cutaneous neoplasm, followed by malignant melanoma and Kaposi’s sarcoma, while epidermoid cysts and viral warts were the commonest tumour-like lesions encountered. Malignant melanoma and Kaposi’s sarcoma show a predilection for the foot, while skin adnexal tumours are commonly seen in the head and neck region. The histological pattern of cutaneous tumours and tumour-like lesions in the current study agreed with the findings of similar works carried out both locally and in other parts of the world.
