Pulse granuloma in a rectocutaneous fistula.

Pulse granulomas are rare foreign body reactions to vegetable material characterized by hyaline rings or starch granules. Pulse granulomas have mainly been reported in association with lung aspirations, the oral cavity with a history of oral procedures and less frequently in intestinal fistulae, colonic diverticulae or stomach ulcers. Only one case involving the skin has been reported in a patient with jejunocutaneous and ileocutaneous fistulae. We report the second cutaneous pulse granuloma in a patient with a rectocutaneous fistula.
