Cutaneous Oxalosis Mimicking Calcinosis Cutis in a Peritoneal Dialysis Patient

Oxalosis is the systemic accumulation of calcium oxalate in tissues throughout the body and can be of primary or secondary etiology. Extrarenal manifestations are rare but can include the cutaneous deposition of calcium oxalate. In this report, we discuss the case of a peritoneal dialysis patient, who presented with cutaneous papules and nodules mimicking calcinosis cutis. Subsequent biopsy resulted in a diagnosis of cutaneous oxalosis.
