Abstract：
Granular cell tumors (GCTs) are rare benign tumors that can occur in any part of the body. They are most commonly found in the head and neck region, especially the tongue. Laryngeal GCTs are rare, accounting for only 3% to 10% of all GCTs. This case report describes a 4-year-old boy with a laryngeal GCT. The patient presented with a history of hoarseness for 2 years. Stroboscopy revealed a large mass occupying the entire length of the left vocal cord. The mass was successfully removed by microlaryngeal surgery with laser ablation. The patient\'s symptoms resolved after surgery, and he had an uneventful recovery. This case highlights the importance of considering GCTs in the differential diagnosis of patients with hoarseness. Early diagnosis and treatment can lead to excellent outcomes.
摘要：
颗粒细胞瘤（GCT）是罕见的良性肿瘤，可发生在身体的任何部位。它们最常见于头部和颈部，尤其是舌头。喉部GCT很少见,仅占所有GCT的3%至10%。此病例报告描述了一个4岁男孩的喉GCT。患者有2年的声音嘶哑病史。频闪镜检查显示，一个大肿块占据了左声带的整个长度。通过激光消融的显微喉部手术成功去除肿块。患者的症状在手术后得到缓解,他恢复得很顺利.该病例强调了在声音嘶哑患者的鉴别诊断中考虑GCT的重要性。早期诊断和治疗可以带来良好的结果。
