Tumoral calcinosis, calciphylaxis, hyperparathyroidism and tuberculosis in a dialysis patient

Abstract

Tumoral calcinosis and calciphylaxis are uncommon but severe complications in ure-mic patients. They occur generally after long-term hemodialysis (HD) treatment explained by ad-vanced secondary hyperparathyroidism and longstanding high calcium phosphorus product (Ca × P). Other factors such granulomatous diseases may worsen the calcium phosphate homeostasis alterations. We report a young male patient treated by HD for 6 years who developed tuberculosis in addition to tumoral calcinosis and calciphylaxis.
