Tumoral calcinosis--an unrecognized disease.

Twenty-six cases of tumoral calcinosis are reported from Kenya. The disease, frequently misdiagnosed, is of unknown origin. It presents as calcified tumours, usually around the hips and buttocks, in muscle and subcutaneous tissue. The tumours are partly solid, partly multiloculated cysts which contain a chalky fluid. They may grow rapidly or very slowly, and are found in children and adults. Both sexes are affected and there is no obvious tribal or geographical localization.
