Prepatellar tumoral calcinosis mimicking soft tissue sarcoma: A case report and review of literature

Abstract

Tumoral calcinosis is a rare, painless tumour-like mass often seen as soft tissue calcifications around joints in adolescents and young adults. The occurrence of this rare entity in the middle aged or elderly population is also rare. The pathology may mimick sarcomatous lesions or granulomatous diseases. A high index of suspicion, imaging and laboratory studies, including histopathological examinations, are needed to make a diagnosis. A 59-year old Nigerian woman that complained of a progressive and painless anterior knee mass, which turned out to be a tumoral calcinosis, is presented.
