Abstract

Tumoral calcinosis is a rare and benign subtype of calcinosis cutis, a group of disorders involving soft tissue calcium deposition. Only 250 cases have been described since 1898; hand involvement is exceedingly rare. We report a case of extensive calcinosis within the flexor sheath of the little finger. Presentation included a painful mass over the volar aspect of the little finger, restricted digit motion, and skin compromise at the site of the mass. Surgical debulking was performed resulting in restoration of finger function.

Keywords: Calcific deposit; calcinosis cutis; case report; hand mass; tumoral calcinosis.
