Recurrent synovial chondromatosis of the index finger--case report and literature review.

We report a case of synovial chondromatosis of the proximal interphalangeal joint of the dominant right index finger with a follow-up of four years. The lesion recurred within a year of complete excision of the fibrous sac containing cartilaginous nodules. Despite early recurrence and extensive calcification around the proximal phalanx, no malignant changes were noted on histological examination. The patient remains asymptomatic for two years after the second operation.
