Cutaneous intestinal metaplasia is a very rare condition that can develop in patients who have intestinal stomas. It presents as a red, eroded or ulcerated plaque at or near a current or prior ostomy site and has characteristic histopathology showing intestinal mucosa interspersed with normal epidermal tissue.

This condition is incredibly rare, with fewer than 5 cases reported in literature. The pathogenesis of cutaneous intestinal metaplasia is unknown. However, it is suggested to be secondary to iatrogenic transfer of intestinal mucosa during surgery. There does not appear to be a sex, racial, or genetic predilection. From the few reported cases, it appears that cutaneous intestinal metaplasia develops decades after initial ostomy procedure.
