Enchondroma protuberans of the phalanx.

Enchondroma protuberans is a rare tumour that rises from an intramedullary enchondroma with an exophytic growth pattern. Although it causes an interesting clinical picture it is benign, and marginal resection of the tumour with bone grafting of the intramedullary defect is curative. We report a case of an enchondroma protuberans of the fifth middle phalanx of the right hand treated by resection, curettage, and autologous bone grafting, with recovery of the normal function of the hand and fingers.
