Giant cell tumour of the middle phalanx of the middle finger.

Giant cell tumour (GCT) of bones in the hand is very rare, only 2% of all hand tumours, but unacceptably high recurrence rates (up to 90%) have been reported by several authors. Diagnosis can be challenging due to its rarity and enchondroma-mimicking characteristics. We report on a case of GCT of the middle phalanx of the left middle finger in a 49-year-old woman who underwent middle phalanx resection and reconstruction with bone grafting. At the 1-year follow-up, no evidence of recurrence was detected and the patient was pain-free.
