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.
本文报道了首例独立于外耳道发生的纤维上皮性息肉病例。一名16岁女性患者因左侧耳部闷胀感前来我院就诊。体格检查发现左侧外耳道入口后壁有一个乳头状肿瘤。活检诊断为良性乳头状瘤后,患者接受了肿瘤切除手术。最终诊断为纤维上皮性息肉。切除术后一周,耳部闷胀感消失。纤维上皮性息肉是一种良性病变,主要发生于皮肤、输尿管肾盂系统和生殖器。在头颈部区域,除皮肤外,有关于舌、梨状窝、下鼻甲和扁桃体纤维上皮性息肉的报道,但尚无关于外耳道独立纤维上皮性息肉的报道。外耳道纤维上皮性息肉,尤其是出现任何症状时,建议切除,如有可能,术前应通过活检确认无恶性病变。
