Tumoral calcinosis of the scalp: An unusual site for a rare tumor.

Abstract

Tumoral calcinosis is a rare calcifying disorder that is associated with deposition of calcium crystals in the periarticular tissues. The mass is most often around the hips, elbows, shoulders, and feet but may be occasionally found elsewhere. We report a case of multiple sporadic tumoral calcinoses in an adult male over the scalp. The scalp as a site of tumoral calcinosis has not been previously reported in adults. Previous surgical excisions done on two occasions had resulted in recurrence of the tumors. This report highlights the need to include tumoral calcinosis in the differential diagnosis of tumors of the scalp.
