Background: The purpose of this study is to determine the frequency and morphological patterns of primary skin sarcoma in University of Benin Teaching Hospital (UBTH), Benin City, Nigeria. Materials and Methods: Data of skin surgical received at the Department of Histopathology, over a 25 year period (1982-2007) were reviewed. Information derived from surgical day books includes socio-demographic data on age, sex, hospital numbers, clinical features and diagnosis. Corresponding slides and blocks retrieved were examined histological. Results: During the 25-year period of this study, 187 cases were malignant skin lesions. Of these, 64 constituting 34.2% were primary skin sarcomas. Kaposi sarcoma (KS) accounted for (n = 57; 30.5% and n = 57; 89.1%) of malignant skin tumours and primary skin sarcoma, respectively. Dermatofibrosarcoma protuberans (DFSP) accounted for (n = 7; 3.7% and n = 7; 10.9%) of all skin malignancy and primary skin sarcomas respectively. The peak incidence of KS and DFSP was in the 4 th and 3 rd decades respectively. The mean age for KS and DFSP was 47.5 ± 1.7 and 35.9 ± 5.9 respectively. The age range for KS and DFSP was 17-78 and 25-65 years respectively. KS and DFSP accounted for male to female ratio of 1.3:1. Of the 28 cases with recorded site distribution, 14 cases (50%) occurred in the leg and foot region. Of these 6 cases of DFSP with recorded site distributions, 4 cases (66.7%) occurred in the trunk. Conclusion: The burden of primary skin sarcoma particularly AIDS associated Kaposi sarcoma in developing countries is worrisome. In view of this, it is important that more awareness and effective HIV/AIDS screening be instituted to reduce the morbidity and mortality of this menace. So that at no distance time, there would be a drastic reduction of skin sarcoma in our society.
