Calcaneal Myxoid Chondrosarcoma: A Rare Case

Abstract

Skeletal myxoid chondrosarcoma is an extraordinarily rare neoplasm with a distinct histological morphology. Although it grows slowly, the clinical course was found to be worse than usual chondrosarcoma. We report a case of a Skeletal myxoid chondrosarcoma in the calcaneus of a 21-year-old female who presented to us with a feature of gradually increasing benign swelling left foot for last two years. Initial investigations were indicating towards a benign lesion for which excision of the lesion was performed. But intra operative findings were suggestive of an aggressive lesion, and to our utter surprise histopathologically it turned out to be Myxoid Chondrosarcoma. Because of its high malignant nature below knee amputation was performed as second definitive surgery. Since her clinical course and radiological pictures were suggestive of benign lesion we got carried away with a diagnosis of chondrmyxoid fibroma and excision of the lesion was attempted without attempting histopathological diagnosis by less invasive methods.
