Enchondroma of the middle phalanx of the fourth finger treated with cancellous bone grafting: A case report

Enchondroma is the most common cartilaginous tumor. It usually involves small tubular bones, and its location is commonly in the metacarpus and fingers of the ulnar side of the hand. We report a case of enchondroma in a 34-year-old woman who presented with a 6-month history of pain, limited range of motion and swelling in middle phalanx of fourth finger of left hand. Radiological evaluation revealed lytic cystic lesion showing with round margins and soap bubble lesion. The specific feature of this case was presence of swelling which usually appears in the late stages. The patient underwent surgery with cyst evacuation, and a cancellous bone graft from the iliac crest was placed at the lesion site. At 6 months follow up, the patient had a full range of motion without any signs of cyst recurrence, and the bone graft was completely replaced. We found this method to be an effective and safe approach for tumor removal and bone reconstruction.
