DUARTE SILVA, Miguel et al. Tumor de Células Gigantes do Unciforme: Caso Clínico. Rev. Port. Ortop. Traum. [online]. 2016, vol.24, n.3, pp.180-188. ISSN 1646-2939.

Primary bone tumors are rare. The giant-cell tumor of bone is a benign, locally agressive tumor formed by mononuclear cells. Its main locations are the distal femur, proximal tibia, distal radius, proximal humerus, proximal femur, sacrum and pelvis. Other locations are very uncommon. The treatment is the excision of the tumor. Recurrence happens in 15% of cases. We present a case of a 17-years old woman with a giant cell tumor of the hamate, who presented with diminished strength and functional compromise of the hand. It is a very uncommon location for this type of tumor. After curettage of the lesion and fill with autologous iliac crest graft, there was recurrence of the tumor. A total hamate resection was performed and flexor carpis radialis tendon was used for interposition. After 6 mounths, the patient was symptom free and recovered total strength and mobility of the hand and wrist.

Keywords : Giant cell tumor; hamate.
