Abstract：
UNASSIGNED: Granular cell tumors (GCT) are rare neoplasms. The most common places are the head and neck. The larynx accounts for 3-10% of cases.
METHODS: We present the case of a man who consulted our Department of Otorhinolaryngology due to long-term progressive dysphonia without dyspnea or dysphagia. Fibrolaryngoscopy revealed a tumor that affected the left vocal cord. The tumor was surgically resected. The histopathological report revealed a laryngeal GCT. Fourteen months after surgery, the patient had no recurrence.
UNASSIGNED: Patients with GCT of the larynx typically have persistent hoarseness, stridor, dysphagia and otalgia, but can also be asymptomatic. A definitive diagnosis is provided by histopathology with immunohistochemistry, and the treatment of choice is surgical resection. Unlike the literature, our report concerns a young man.
CONCLUSIONS: Granular cell tumor is a rare tumor of the larynx and should be considered a differential diagnosis in all adult men with long-standing dysphonia.

摘要：
未经证实：颗粒细胞瘤（GCT）是罕见的肿瘤。最常见的部位是头部和颈部。喉部占病例的3-10%。
方法：我们介绍了一名男子，他因长期进行性发声障碍而咨询了我们的耳鼻咽喉科，但没有呼吸困难或吞咽困难。纤维喉镜检查显示肿瘤影响了左声带。手术切除了肿瘤。组织病理学报告显示喉部GCT。手术14个月后,患者无复发。
未经证实：喉部GCT患者通常有持续性声音嘶哑，stridor,吞咽困难和耳痛,但也可以是无症状的。通过组织病理学和免疫组织化学提供明确的诊断，选择的治疗方法是手术切除。与文学不同，我们的报告涉及一个年轻人。
结论：颗粒细胞瘤是一种罕见的喉部肿瘤，在所有患有长期发音困难的成年男性中，应考虑鉴别诊断。
