Tumoral calcinosis with sedimentation sign

Massive periarticular calcifications may occur in metabolic disturbances with an increased calcium phosphate product, e.g., renal insufficiency, hyperparathyroidism, vitamin D intoxication, milk-alkali syndrome. Identical massive calcium deposits may be found in patients with normal calcium metabolism and a normal skeleton in the entity known as “tumoral calcinosis”. The disease seems to be very rare. Until 1965 only a few cases were described in the literature. According to some authors (Palmer, 1966) it may occur more often, but since patients do not suffer from pain in the initial stages of the disease, they are not discovered.
