Schwannoma, also known as neurilemmoma, is a tumor of the nerve sheath, which most often occurs in the peripheral nerves of the extremities. Schwannoma can be accompanied by symptoms such as pain, paresthesia, and Tinel sign; however, patients can also be asymptomatic. Here, we present the case of a 17-year-old woman who presented with a slowly growing, asymptomatic, postauricular mass that appeared 10 years prior. Ultrasonography was performed, and the mass was thought to be an epidermal inclusion cyst. However, the clinical manifestation during surgery was not correlated to an epidermal inclusion cyst, leading to the suspicion of schwannoma from the posterior branch of the great auricular nerve. After a meticulous dissection, schwannoma was diagnosed based on a permanent section biopsy. Postoperative complications and recurrence were not observed. Schwannoma in the peripheral nerve area of the face is rare. Therefore, an investigation of tumors that occur where the nerve passes using imaging and clinical features is necessary to confirm the diagnosis of schwannoma and to establish suitable treatment methods.
神经鞘瘤，也称为神经膜瘤，是一种神经鞘肿瘤，最常发生于四肢的周围神经。神经鞘瘤可伴有疼痛、感觉异常和Tinel征等症状；然而，患者也可能无症状。在此，我们报告一例17岁女性病例，该患者有一个10年前出现的、生长缓慢、无症状的耳后肿块。进行了超声检查，该肿块被认为是表皮样囊肿。然而，手术中的临床表现与表皮样囊肿不符，从而怀疑是来自耳大神经后支的神经鞘瘤。经过细致解剖，根据永久切片活检诊断为神经鞘瘤。未观察到术后并发症和复发情况。面部周围神经区域的神经鞘瘤较为罕见。因此，有必要利用影像学和临床特征对神经走行部位发生的肿瘤进行调查，以确诊神经鞘瘤并制定合适的治疗方法。
