Giant cell tumor of bone (GCT-B) accounts for approximately 5% of all primary bone tumors and 20% of all benign bone tumors. Its occurrence in the hand is rare, accounting for <2% of cases. In the Rizzoli study covering the 50 years between 1947 and 1997, of the 900 patients with GCT-B, only 8 (0.9%) had GCT in the small bones of the hand and no phalangeal lesions were observed. A five-decade review of GCT of bone from the Mayo Clinic came up with just five cases of GCT in the phalanges (and 13 overall in the small bones of the hand). Our experience at the King Faisal Specialist Hospital covered the period between 1985 and 2020. During these 35 years, we saw 350 patients with GCT-B, of whom only 2 (<1%) patients presented with phalangeal lesions. Both patients were treated by excision of the involved phalanx and nonbiological reconstruction using a Kirschner wire and cement spacer. A literature review and management options for this rare presentation site in GCT-B are discussed.
