Fibrofolliculoma is a rare benign follicular neoplasm in pilar complex, histopathologically characterized by hyperplastic follicular infundibulum with a central keratinous plug, and anastomosing strands of basaloid cells branching into dense surrounding stroma. Fibrofolliculoma is benign skin tumor with the following features, multiple growths, autosomal inheritance, and associated skin lesions, while solitary form with identical clinical and microscopic features are relatively rare and nonhereditary. We report on a 41-year-old man with a solitary, bean sized mass on his left tragus which histopathologically shows a typical fibrofolliculoma. (J Clinical Otolaryngol 2007;18:122–124)
