Glomus tumors are rare benign tumors. The majority of them affect the skin the most and are rarer in the trachea, where the glomus bodies may not be present. Only scarce reports of tracheal glomus tumors have been reported solely with case reports of relevant articles.
A 53-year-old man, with a free previous medial history, presented to our hospital with tracheal mass which was incidentally found. He did not complain of any specific symptoms associated with the tracheal tumor. The contrast-enhanced chest computed tomography (CT) revealed an avid enhancing nodular lesion, which is similar to blood vessels, in the trachea, 3 cm above the carina level without definite airway obstruction.
Successful tracheal resection and end-to-end anastomosis were performed on the patients; therefore, the final post-operative pathologic findings revealed a benign tracheal glomus tumor. The follow-up CT scan four months after operation showed complete removal of the tumor.
Tracheal glomus tumors, even rare entities, could be considered as a differential diagnosis if a highly enhancing mass appears on CT images.
血管球瘤是一种罕见的良性肿瘤。大多数发生在皮肤，在气管中较为少见，且气管内可能不存在血管球。仅有少数关于气管血管球瘤的报告，且均为相关文献的病例报告。
一名 53 岁男性，既往无特殊病史，因气管内占位就诊于我院。患者无与气管肿瘤相关的特殊症状。增强胸部 CT 显示隆突上 3cm 处气管内有一个强化的结节状病灶，类似血管，未见明确气道阻塞。
患者成功进行了气管切除端端吻合术；术后最终病理结果显示为良性气管血管球瘤。术后 4 个月的 CT 扫描显示肿瘤完全切除。
如果 CT 图像上出现高度强化的肿块，即使是罕见的实体，也应考虑气管血管球瘤作为鉴别诊断。
