颗粒细胞瘤（ＧｒａｎｕｌａｒＣｅｌＴｕｍｏｒ，ＧＣＴ）是一种罕见的肿瘤。常发生于舌、皮肤及皮下组织、乳腺等部位。呼吸道ＧＣＴ发生率低，若累及呼吸道则以喉和支气管较多见。原发部位位于气管的ＧＣＴ极少，截止到１９８６年英文文献仅有１０例气管ＧＣＴ报道，国内近１３年未有气管颗粒细胞瘤报道，。本文报道１例３０岁女性气管ＧＣＴ患者，结合文献对气管ＧＣＴ的组织发生、临床表现、病理特点、诊断与鉴别诊断以及治疗方法等问题进行讨论。
Granular Cell Tumor (GCT) is a rare tumor. Often occurs in the tongue, skin and subcutaneous tissue, breast and other parts. The incidence of GCT in the respiratory tract is low. If the respiratory tract is involved, the larynx and bronchi are more common. The GCT with the primary site located in the trachea was very rare. As of 1986, only 10 cases of tracheal GCT were reported in the English literature. There was no report of tracheal granulosa cell tumor in the past 13 years. This article reports a case of 30-year-old female patients with tracheal GCT, combined with the literature on the histogenesis, clinical manifestations, pathological features, diagnosis and differential diagnosis and treatment of tracheal GCT.
