Uremic tumoral calcinosis in the cervical spine: case report.
Tumoral calcinosis is an uncommon condition characterized by the calcification of periarticular soft tissue. In uremic patients the disease is secondary to metabolic disturbances in predisposed patients. The authors report the case of a 73-year-old woman who presented with a new painful cervical mass while undergoing continuous ambulatory peritoneal dialysis for long-standing end-stage renal disease (ESRD). ⋯ The authors conducted a search of the PubMed and EMBASE databases and identified 7 previously reported cases of UTC of the cervical spine. They present a summary of these cases and discuss the etiology, diagnosis, and management of the condition. Although the metabolic disturbances seen in patients undergoing dialysis can lead to tumoral calcinosis, most reported cases involve large joints such as the shoulder or the hip; however, the spine can also be affected and should be considered in the differential diagnosis of patients with uremia as it can mimic aggressive bone-forming neoplasms.
