Le fibrome chondromyxoïde. À propos d'une localisation phalangienne du pouce

Chondromyxoid Fibroma is a rare benign osseous tumor especially in the hand, because the hand represents less than 3% of all osseous locations. It can causes problems of differential diagnosis with several types of tumors and in particular with chondrosarcoma, for which the management is totally different. We report a case of location of a chondromyxoid fibroma in a phalanx of the thumb, which caused problems of differential diagnosis with chondroma and chondrosarcoma. There were 2 recurrences after local excision. A wide resection with massive cancellous aotograft prevented further recurrence and the patient is disease free with a follow up of 7.5 years.
