A case of subungual osteochondroma.
Subungual osteochondroma is a rare form of benign bone tumor characterized by distinctive histopathological and radiological findings. The major clinical manifestation is a firm mass with tenderness. It must be differentiated from other similar diseases such as subungual exostosis, glomus tumor, and enchondroma to determine the proper surgical procedure. A 13-year-old boy had a history of a growing tender mass on the right third toe which recurred after simple excision. He was treated by careful dissection and total excision under local anesthesia. Histologic findings included a trabecular bone formation covered with hyaline cartilage cap and were compatible with osteochondroma.
