The Tanzania Cancer Registry at Mubimbili Medical Centre, Dar es Salaam, Tanzania was reviewed for squamous cell carcinoma of the skin in non-albino African subjects. The data was analysed for age, sex, site and predisposing factors. Our results were then compared with studies previously carried out in Tanzania, elsewhere in Africa and also on Blacks in America. Squamous cell carcinoma of the skin was found to be a common malignancy, and the commonest skin cancer. Its peak. was in the 40-49 years age group though it could occur in children under five years of age. The most affected site was the lower limb, followed by the head and the neck. The penis in the male and the vulva in the female were the third most affected sites. The scalp and the lip were more affected in females than males. Chronic trauma, chronic ulcers, and scars were the main predisposing risk factors to the lower limb and the scalp, while ultra violet radiation to the head and neck, and smegma of the uncircumcised penis were thought to be predisposing risk factors.
