Gastric calciphylaxis in a patient with a functioning renal allograft

Calciphylaxis or calcific uremic arteriolopathy (CUA), not uncommon in the dialysis population, has also been reported in renal transplant recipients with varying stages of renal dysfunction. While cutaneous involvement in both populations is the most common feature, visceral involvement is rarely described. We report a patient with a long-standing functioning renal allograft who presented with visceral calciphylaxis in a Dieulafoy lesion requiring gastrectomy. Histopathology revealed typical features of CUA. The current literature describing CUA in post-transplant patients is reviewed.
