Enchondroma protuberans: a case report

Enchondroma protuberans is a rare benign cartilaginous tumor. There have been only 5 cases previously described in the world literature. It must be differentiated from other more common and aggressive tumors to avoid radical resection. A case report of a 7-year-old boy presenting with enchondroma protuberans in the third metacarpal is presented. The patient underwent an initial incisional biopsy followed by a marginal resection of the soft tissue component and intramedullary curettage. After a 36-month follow-up period, there is no evidence of recurrence.
