Schwannomas are well encapsulated mesenchymal tumors of peripheral nerves, with slow growth. The laryngeal schwanomma is exceptional, we present a case not described in the literature of shwannoma in the pre epiglottic space. A 50-year-old woman, who had a history of foreign body sensation for 4 years ago, progressing to high dysphagia and hoarseness. Direct laryngoscopy in suspension demonstrated a regular submucosal mass in the supraglottic space, reducing pharyngo-laryngeal space. CT and MRI concluded with a benign tumor of the preepiglottic space. External surgical excision was performed and a primary tracheotomy was required. The histological examination with an immunochemical study confirmed a benign schwannoma. There was no complication postoperatively. The outcome was excellent after 2 years of follow-up.
施万瘤是周围神经的包膜完整的间叶性肿瘤,生长缓慢。喉施万瘤较为罕见,我们报告一例文献中未描述的会厌前间隙施万瘤。一名50岁女性,4年前有异物感病史,进展为高度吞咽困难和声音嘶哑。悬吊喉镜检查显示声门上间隙有一个规则的黏膜下肿块,使咽喉间隙缩小。CT和MRI诊断为会厌前间隙良性肿瘤。进行了外部手术切除,且需要一期气管切开术。组织学检查及免疫化学研究证实为良性施万瘤。术后无并发症。随访2年,结果良好。
