Giant cell reparative granuloma (GCRG) is a rare, pseudotumoural intraosseous lesion, considered a reactive injury after repeated trauma. Reactive lesions and benign bone tumours may show aggressive clinical and radiographic findings. Differential diagnosis must be performed in order to offer suitable treatment to the patient. Excisional biopsy and curettage of the lesion are the preferred methods of treatment. We present the first case of a GCRG of the distal phalanx of the left little finger in a professional violinist.
