ABSTRACT
Soft-tissue chondroma is a rare and benign cartilaginous tumour often localized in the extremities. The thumb is very rarely affected. We report a new case typical for this lesion with review of literature. 43 year-old man presented with soft tissue tumour of the left thumb for about 4 years without any symptoms. Radiographs of the thumb showed a calcification out of the bone. Surgery resection of the tumour was complete and easy. Histological examination confirmed the diagnosis of soft-tissue chondroma. There was not tumoral recurrence at three years follow-up. Soft tissue chondroma is not a diagnosis evoked when we have a soft tissue tumor of the hand. Diagnosis is confirmed by pathology which should eliminate a low grade chondrosarcoma. Complete surgical resection will avoid recurrence
