Enchondroma protuberans of the phalanx: a case report.

Enchondroma protuberans, which is defined as an exophytic enchondroma of a long bone, is a rare condition. There have been 6 previously reported cases with only 1 case occurring in the hand. We report a case of an enchondroma protuberans of the ring finger middle phalanx treated by marginal excision of the soft-tissue component, intramedullary curettage, and placement of calcium phosphate cement. There was no evidence of local recurrence at the 1-year follow-up examination.
