Gaint-cell tumor of bone is an infrequent primary neoplasm,accounting for approximately 20% all primary bone tumors. The three most common sites are the distal femur, proximal tibia, and distal radius. Giant-cell tumor of tarsal bone is rare, especially, located in the calcaneus. The estimated incidence in giant-cell tumor of the calcaneus is about 0.3%. It is predominantly a tumor of young adult, slightly more with giant-cell tumor of the calcaneus as reported. Clinical manifestation, iperative method and result are discussed with short review of the literature.
