Granular cell tumours (GCTs) are a rare form of neoplasm found throughout the body. Tracheobronchial involvement is less common. We describe a case of tracheal GCT in a 37-year-old Japanese woman presenting with throat discomfort. A tracheal tumour was found during laryngoscopy for undefined throat discomfort. Bronchoscopy demonstrated a white sub-epithelial solitary nodule on the tracheal wall, and pathological examination of the biopsy samples confirmed GCT. No therapeutic procedures were performed, and the tumour is currently under strict observation. Throat discomfort is a rare presentation of tracheal tumours, but an early inspection using laryngoscopy and bronchoscopy may be helpful in determining an accurate diagnosis.
颗粒细胞瘤（GCTs）是一种在全身都可发现的罕见肿瘤形式。气管支气管受累较少见。我们描述了一例37岁日本女性的气管颗粒细胞瘤病例，该患者表现为咽喉不适。在因不明原因咽喉不适进行喉镜检查时发现了气管肿瘤。支气管镜检查显示气管壁上有一个白色的上皮下孤立结节，活检样本的病理检查确诊为颗粒细胞瘤。未进行治疗，目前对该肿瘤进行严密观察。咽喉不适是气管肿瘤的罕见表现，但早期使用喉镜和支气管镜检查可能有助于做出准确诊断。
