Rare case of recurrent hair in the floor of the mouth

Abstract

Introduction: Here we report an unusual case of recurrent hair growth in Wharton's duct in an adult male and there by exploring possible cause of it. Observation: The patient presented with recurrent hair growth in the floor of the mouth. The hair growth occurred at the right submandibular duct opening on all occasions. The patient underwent CT scan of the salivary glands which showed one stone approximately 3mm at the site which was removed under local anesthesia. Commentary: Recurrent hair growth in the floor of the mouth is rare incident. Although multiple etiologies have been described in the literature, we initially thought of the retrograde theory as patient had beard but concluded that it could be due to heterotopia as to be the possible cause of it.
