Schwannoma is a benign tumor originating from the peripheral nerve sheath. The clinical symptoms of tracheal schwannoma depend on the location of the tumor, and the most common clinical symptoms are cough and hemoptysis. The most effective treatment for benign tumors is complete resection of the primary lesion at an early stage. Our experience has demonstrated that primary tracheal schwannoma can be safely excised with a high-frequency electric knife in a minimally invasive manner.
We report a 61-year-old asymptomatic woman who underwent chest computed tomography (CT), which accidentally found an intraluminal tracheal mass without enlarged lymph nodes. Then, the patient underwent bronchoscopy, which found that the tracheal mass originated from the left wall of the upper trachea, was less than 1.5 cm in size, immovable, smooth and 4 cm away from the vocal cord, resulting in partial upper respiratory tract obstruction. Treatment was performed using an endoscopic resection for en bloc removal of the tracheal mass. The diagnosis was primary tracheal schwannoma. A follow-up was performed after endoscopic surgery, and bronchoscopy and thoracic CT were used to monitor whether there was a recurrence. At present, there is no evidence of recurrence, and the patient had a good quality of life. Endoscopic resection may be effective and safe in the treatment of primary tracheal schwannoma.
Primary tracheal schwannoma is a very rare benign tumor. In this case, we cured it by complete endoscopic resection.
神经鞘瘤是一种起源于周围神经鞘的良性肿瘤。气管神经鞘瘤的临床症状取决于肿瘤的位置，最常见的临床症状是咳嗽和咯血。对于良性肿瘤，最有效的治疗方法是早期完整切除原发灶。我们的经验表明，原发性气管神经鞘瘤可以通过高频电刀以微创方式安全切除。
我们报告一名61岁无症状女性，其接受胸部计算机断层扫描（CT）时意外发现气管腔内肿物，无淋巴结肿大。随后，患者接受支气管镜检查，发现气管肿物起源于气管上段左壁，大小小于1.5 cm，固定不动，表面光滑，距声带4 cm，导致上呼吸道部分梗阻。采用内镜切除术整块切除气管肿物。诊断为原发性气管神经鞘瘤。内镜手术后进行随访，使用支气管镜和胸部CT监测是否复发。目前，没有复发迹象，患者生活质量良好。内镜切除术治疗原发性气管神经鞘瘤可能有效且安全。
原发性气管神经鞘瘤是一种非常罕见的良性肿瘤。在本病例中，我们通过完整的内镜切除将其治愈。
