Tumoral Calcinosis-A Case Report of Rare Soft Tissue Calcification

Abstract

Tumoral calcinosis is rare, of an unknown origin, and usually characterized by hyperphosphatemia, normocalcemia, and focal and multifocal periarticular soft-tissue calcifications. Tumoral calcinosis occurs in superficial soft tissues, most commonly in the hands, feet, and elbow areas. We present a case of tumor calcinosis in a 47-year-old male patient who had the history of diabetes mellitus (DM) for 10 years and DM nephropathy with end-stage renal disease under hemodialysis. He had a mass (5 cm x 6 cm x 9 cm) at his right elbow and no upper limb ROM (range of motion) limitation. There was no pain associated with the mass, but there were some limitations on the patient's ability to dress and undress himself because of the huge size of the mass. After detailed examinations and surgical intervention, the clinical and pathologic findings were tumoral calcinosis. We review the literature and discuss this rare disease.
