Granular cell tumors are uncommon neoplasms of the head and neck that usually involve the tongue. The larynx is an atypical site of involvement in adults and a rare site in children. We report two cases of subglottic granular cell tumors, one in a 10-year-old boy and the other in a 6-year-old girl. Although both were initially misdiagnosed as having asthma, radiologic, laryngoscopic, and histologic evaluation of the obstructions eventually furnished the correct diagnosis. The patients were successfully treated by surgical excision of their subglottic masses. The history, presentation, pathologic findings, management, and prognosis of this rare pediatric laryngeal tumor are explored.
颗粒细胞瘤是头颈部罕见的肿瘤，通常累及舌头。喉是成人中不常见的受累部位，在儿童中则是罕见部位。我们报告两例声门下颗粒细胞瘤，一例发生在一名10岁男孩，另一例发生在一名6岁女孩。尽管最初两者都被误诊为哮喘，但对梗阻进行的放射学、喉镜检查和组织学评估最终得出了正确诊断。通过手术切除声门下肿物，患者得到了成功治疗。本文探讨了这种罕见的小儿喉部肿瘤的病史、表现、病理发现、治疗及预后。
