Colostomy site pulse granuloma: A case report and review of literature

Pulse granuloma is a benign condition characterized by foreign body reaction to vegetable matter like seeds of leguminous plants. We report a unique case of pulse granuloma at an extra-oral location, colostomy site. Microscopic examination revealed a granulomatous reaction in response to vegetable matter characterized by irregularly sized oval hyaline structures with central basophilic granules. To the best of our knowledge, this is the first reported case of a pulse granuloma at the colostomy site. Awareness and familiarity of this entity helps in avoiding an erroneous diagnosis of systemic inflammatory disease or infectious disease.
