Giant Cell Tumor of the Talus: A case report and review of literature

Abstract

Giant cell tumor is described as neoplasm of undifferentiated mesenchymal stromal cells with presence of abundant, multi-nucleated giant cells. It is basically a benign aggressive tumor which involves the epiphyseometaphyseal end of long bones. Giant cell tumor rarely involves small bones of hand and foot, and is a rare finding within the talus. In the case report, a patient complains of pain and swelling over the left ankle for one year. Plain radiographs and computerized tomography scan (CT) and CT guided fine needle aspiration cytology suggested a diagnosis of giant cell tumor. The tumor was of grade І according to Campanacci grading and there was not cortical break. Treatment consisted of intralesional curettage and an autogenous cancellous bone graft. After two years follow-up, the patient was able to walk with full weight bearing on the affected limb without pain. There were no signs of recurrence both clinically or radiographically.
