title: Fibrous histiocytoma of the tongue base.
abstract: Fibrous histiocytomas usually occur in the dermis and superficial subcutis. Involvement of the tongue is extremely rare. A 51-year-old female, referred to us for a sore throat, was noted on intraoral examination to have a polypoid mass with a smooth mucosal surface on the base of the tongue. This lesion was excised because of its probable continuing growth. This tumor, which showed staining for alpha 1-antichymotrypsin, was pathohistologically diagnosed as fibrous histiocytoma. This was the second documented case of fibrous histiocytoma of the tongue.
