%X This paper reports the first case of fibroepithelial polyp arising independently of the external auditory canal. A 16-year-old female patient presented to our clinic for aural fullness of the left side. Physical examination revealed a papillomatous tumor at the posterior wall of the inlet of the left external auditory canal. After biopsy, which yielded a diagnosis of benign papilloma, the patient underwent tumor excision. Final diagnosis was fibroepithelial polyp. One week after resection, aural fullness had resolved. Fibroepithelial polyp is a benign lesion and occurs mainly in the skin, ureteropelvic system, and genitals. In the head and neck area, there are reports on fibroepithelial polyp of the tongue, piriform fossa, inferior nasal turbinate, and tonsil, in addition to the skin, but none on independent fibroepithelial polyp of the external auditory canal. Excision of fibroepithelial polyp of the external auditory canal is advisable, especially in the presence of any symptoms, and should be preceded by confirmation of nonmalignancy by biopsy, if possible. 1. Introduction Fibroepithelial polyp is a benign lesion of mesothelial origin and is one of the most common cutaneous lesions. It is generally an incidental finding on the skin of the neck, trunk, or face and is also known as fibroma or acrochordon, representing a nonspecific and benign growth pattern as opposed to a specified entity [1]. In addition to the skin, fibroepithelial polyp infrequently occurs in the ureteropelvic system, genitals, or bronchus [2¨C5]. Fibroepithelial polyp is benign and presents with an indolent clinical course. However, problems may arise depending on location, especially in the case of polyps in the bronchus that cause occlusion. To the best of our knowledge, there is no report on fibroepithelial polyp arising independently of the external auditory canal. Although only one report about fibroepithelial polyp of the external auditory canal has been published, this was believed to be a reactive change in the skin overlying an osteoma [6]. Therefore, we present this very rare case and also review the literature of fibroepithelial polyp occurring independently in the head and neck area. 2. Case Report A 16-year-old female Japanese patient was referred to our clinic by an otolaryngologist for suspected papilloma of the external auditory canal; she presented to our clinic with a 2-week history of aural fullness of the left side. She had no other medical problems except allergic rhinitis triggered by house dust, mites, and pollen from Japanese cedar and cypress trees. On
