title: Granular cell tumor of the floor of the mouth - a case report.
abstract: The granular cell tumor is an uncommon lesion and, when arising in the head and neck, principally involves the tongue and larynx. A patient with a granular cell tumor of the floor of the mouth is reported. Management is usually accomplished by complete local excision, but longterm follow-up is mandatory. Distinguishing the epithelial (pseudo-epitheliomatous) hyperplasia from a well differentiated squamous cell carcinoma is critical to avoid unnecessary radical surgery. At present the lesion is considered to be a true neoplasm, likely of Schwann cell origin, and clinically benign.
