A Nephrocutaneous Fistula Presenting as a Chronic Back Wound

Renal replacement lipomatosis is a rare condition that when arises usually presents as back or flank pain, dysuria, or an abdominal mass. We present a case of renal replacement lipomatosis that presented instead as a chronic back wound. Given that this pathology is readily treated with surgical intervention when performed in a timely manner, it is important to consider this as a possible diagnosis when chronic back wounds deviate from the expected time course of healing.
