Diagnosis and management of giant cell tumour of talus: A case report

Abstract

Giant cell tumor (GCT) of bone involving small bones of hand and feet is a rare entity. But in foot and hand it is more aggressive and recurrence rate is high as compared to long bones. We report a rare case of GCT of talus that was managed on the lines of tuberculosis by an orthopaedic surgeon for six months. Core biopsy of the lesion revealed multinucleate giant cells on histopathological examination suggestive of GCT or aenurysmal bone cyst (ABC). Extended curettage and bone grafting was done. Histopathology of the curettage confirmed the lesion as GCT. The patient was followed for a period of 24 months and there was no local recurrence or lung metastasis. So it is concluded lytic lesion involving small bones of hand and feet can be a presentation of any disease ranging from infection to a tumor and GCT should always be kept as a differential. And these lesions should be routinely subjected to core or open biopsy to confirm the clinical diagnosis.
