[Tumoral calcinosis].
Tumoral calcinosis is a distinct entity, which is rarely seen in Europe and North America but much more common in black Africans. Typical symptoms are calcified nodules, which grow while remaining asymptomatic and are found in the tissues adjacent to the large joints of the body. Histologically there is collagen necrobiosis initially, which results in aggregates of densely calcified material. The aetiology is unknown, but the condition is probably a form of dystrophic calcification caused by mechanical injury. A patient with tumoral calcinosis is presented, and the clinical and histological findings are described.
