RESUMO

La oxalosis es una enfermedad derivada del depósito de oxalato cálcico fuera del aparato urinario. Los lugares de depósito extrarrenales más frecuentes incluyen el hueso, el miocardio, la retina, los vasos sanguíneos y la piel, lo que da lugar a las manifestaciones clínicas de esta enfermedad. En la piel las alteraciones pueden deberse a la afectación de los vasos sanguíneos, lo que da lugar a la aparición de cuadros de livedo reticularis, acrocianosis, úlceras y gangrena. Presentamos el caso de una mujer de 60 años con historia de litiasis renal recidivante, que le llevó a una insuficiencia renal terminal que requirió hemodiálisis y posteriormente diálisis peritoneal. La paciente desarrolló de forma súbita la aparición de elementos cutáneos de color rojo-violáceo, dolorosos a la palpación compatibles con livedo reticularis que evolucionaron a úlceras. La biopsia cutánea reveló una vasculopatía por oxalato.En este artículo se describen las características de este raro proceso, su diagnóstico diferencial con la calcifilaxis y las alternativas terapéuticas (AU)


Oxalosis is a disease caused by the deposition of calcium oxalate in extrarenal tissues, most commonly bone, myocardium, retina, blood vessels, and skin, causing the clinical manifestations of the disease. Involvement of the blood vessels of the skin can give rise to livedo reticularis, acrocyanosis, ulcers, and gangrene. We present the case of a 60-year-old woman with a history of recurrent renal lithiasis that had led to terminal renal failure requiring hemodialysis and, subsequently, peritoneal dialysis. The patient developed tender red-violaceous skin discoloration of sudden onset, consistent with livedo reticularis; the lesions progressed to form ulcers. Skin biopsy revealed oxalate vasculopathy. In this article we describe the characteristics of this rare disorder, its differentiation from calciphylaxis, and the therapeutic options (AU)
