Vegetable or pulse granuloma in the nasal cavity.

Vegetable granuloma or pulse granuloma results from the implantation of food particles of vegetable origin. Pulse granulomas have mainly been reported in association with lung aspirations, the oral cavity with a history of oral procedures and less frequently in gastrointestinal tracks. We report a 31-year-old woman who presented with right nasal obstruction and was found to have a firm mass in the right nasal cavity. Paranasal sinus computerized tomography scans identified a calcified ring lesion in her right nasal cavity. Endoscopic sinus surgery was performed, and pathology examination revealed a lesion consistent with a pulse granuloma that contains starch granules with cellulose envelopes appearing as hyaline rings surrounded by inflammation cells and concentrically arranged delicate connective tissue. Pulse granuloma is a well described entity with distinct histopathology. However, pulse granulomas are rare, and especially extraoral pulse granulomas are extremely rare. We found that pulse granuloma can be occurred in the nasal cavity through regurgitation.
