Tumoral calcinosis: a case report and review of the literature.

Tumoral calcinosis rarely occurs in the hand. It is an uncommon familial disease suggesting an autosomal recessive gene pattern, often with laboratory findings of hyperphosphatemia and normocalcemia. Our patient had bilateral hand involvement, including local calcinosis cutis of the skin and bone changes not previously reported in the literature. At a 2-year follow-up after two lesions were excised from her left hand, one lesion had completely resolved and the other recurred. Two large symptomatic lesions and one area of local calcinosis cutis in her right hand have recently been excised.
