title: Tumoral calcinosis in the neck region involving an unusual site in a hemodialysis patient.
abstract: Tumoral calcinosis is a rare disorder characterized by calcium salt deposition in the periarticular soft tissue region. It often occurs in the hip, elbow, shoulder, foot, and wrist. Soft tissue calcification associated with tumoral calcinosis is rare in the head and neck. The present case describes a 65- year-old male who had been on hemodialysis for 3 years. A bulky mass, containing chalky amorphous calcified material, occurred at the lower neck and superior mediastinum. Chronic renal failure is a common condition associated with secondary tumoral calcinosis. The pathogenesis has been progressively unraveled, which indicates that secondary hyperparathyroidism and tissue injury play a part in multifactorial calcification. Laryngoscope, 126:E196-E198, 2016.
