Regresión post-trasplante de la calcinosis tumoral urémica / Postransplant regresion of uremic tumoral calcinosis

RESUMEN

La calcinosis tumoral urémica es el depósito masivo de fosfato cálcico en tejidos blandos periarticulares de los huesos largos. Su prevalencia se estima del 1-7% de pacientes con largo tiempo en hemodiálisis y aunque su etiopatogenia es desconocida, se asocia a hiperparatiroidismo secundario severo, elevación del producto calcio- fósforo o hiperfosforemia. Presentamos un caso de calcinosis tumoral en hombro, debido a hiperfosforemia y elevación del producto calcio-fósforo, tratado mediante diálisis intensivas con líquido bajo en calcio, con rápida recidiva y desaparición tras someterse a trasplante renal

ABSTRACT

Uremic tumoral calcinosis is the massive calcium-phosphate deposits in periarticular tissues, usually around large joints. It has been described between 1-7% hemodialysis patients and although its etiopathogenesis is unknown, it is associated to severe hyperparathyroidism, elevation of the serum calcium-phosphorus product or hiperphosphataemia.We describe the case of tumoral calcinosis in the shoulder due to hiperphosphataemia and elevated calcium-phosphorus product, treated with low calcium intensive dialysis and fast relapse that disappears after renal transplantation
