title: [Tumorous calcinosis in hemodialysis: anatomo-clinical study apropos of 3 cases].
abstract: Three patients (2 females, 1 male) with a mean age of 51.4 years receiving long term hemodialysis affected by tumoral calcinosis were analysed. Clinical, radiological and pathological features were evaluated and pathogenic were reviewed. The joints involved int the cases presented in this report were the hip shoulder and finger. The lesions were bilateral in shoulder. An increased calcium-phosphorus product (Ca x P) was observed in all patients with secondary hyperparathyroidism in one case. Surgery was carried out in all patients. No relapse of the tumoral calcinosis was observed after surgery. The most important pathogenic factor involved in uremic tumoral calcinosis is an increase in calcium-phosphorus product (Ca x P) not necessarily related to hyperparathyroidism. Therefore, maintaining the calcium x phosphate product within the normal range appears to be the most important factor ito prevent the appearance of uraemic tumoral calcinosis.
