The external ear canal may be occluded by a rare tumor of the tympanic membrane. We reported herein a case of solid schwannoma arising from the tympanic membrane of a 29-year-old man. It presented as a circumscribed and encapsulated tumor of the external ear canal. The definite diagnosis was based on a careful microscopic examination and pathological findings. A precise excision of the tumor together with part of the tympanic membrane, followed by a myringoplasty was performed. To the best of our knowledge, our case should be the first reported case of this entity in the world literature.
外耳道可能被一种罕见的鼓膜肿瘤阻塞。我们在此报告一例29岁男性鼓膜来源的实性施万瘤病例。它表现为外耳道的一个边界清晰且有包膜的肿瘤。明确诊断基于仔细的显微镜检查和病理结果。对肿瘤连同部分鼓膜进行了精确切除，随后进行了鼓膜成形术。据我们所知，我们的病例应是世界文献中首例报道的该病例。
