Uremic tumoral calcinosis: acute hand presentations mimicking infection.

Abstract

Tumoral calcinosis is an uncommon condition of the hand characterized by deposition of calcium salts in the soft tissues of the extremities. The condition may be hereditary or acquired. Acquired tumoral calcinosis, also called tumoral calcification, is a rare manifestation of renal osteodystrophy due to derangement in divalent ion metabolism. Two chronic dialysis patients with tumoral calcification of the hand are presented. These cases are unusual in their rapid onset of presentation, mimicking acute infection. Prompt recognition of the condition may allow early nonsurgical intervention to preserve function.
