Glomus tumours (GTs) are rare benign neoplasms arising from modified smooth muscle cells (SMCs) surrounding arteriovenous anastomosis. Typically, these tumours are found in the distal portion of the digits, especially under the fingernails. A GTs originating from the trachea is extremely rare. We are presenting the case of a Caucasian man in his early 80s, presenting with upper airway obstruction and massive bleeding caused by a large tracheal tumour to which final diagnosis of glomangioma of the trachea was retained. Methods of diagnostics, management and follow-up are documented. The incidence of GTs accounts about 1.6% of soft tissue tumours, and they are mainly located in dermal and subcutaneous tissue but can be equally find throughout the body. However, tracheal glomus tumours are the most clinically significant as they can be malignant and cause life-threatening condition through central airway obstruction. Histological analysis provides certainty of diagnosis, and surgical resection is the main treatment option.
血管球瘤（GTs）是一种罕见的良性肿瘤，起源于围绕动静脉吻合的平滑肌细胞（SMCs）。这些肿瘤通常发生在远端指节，尤其是指甲下。起源于气管的 GTs 极为罕见。我们报告了一例 80 多岁的高加索男性，因大气道阻塞和气管大肿瘤引起的大量出血而就诊，最终诊断为气管血管球瘤。记录了诊断、治疗和随访的方法。GTs 的发病率约占软组织肿瘤的 1.6%，主要位于真皮和皮下组织，但也可以在全身各处发现。然而，气管血管球瘤是最具临床意义的，因为它们可能是恶性的，并通过中央气道阻塞导致危及生命的情况。组织学分析提供了明确的诊断，手术切除是主要的治疗选择。
