A denture complication: sarcoid-like foreign body granulomas of the tongue.

Sarcoidosis in the oral cavity occurs extremely rare (there have been described only 47 cases in the literature) and is almost always doubtful. We describe a protruding painful nodule (1 cm) on the apex of the tongue of a 65-year-old female, adjacent to the site of irritation of a new denture. Histologically it was confluent mass of non-caseous granulomas, rich in Langhans' cells.
