Pleomorphic adenoma (PA) is the most common benign histological form of salivary gland tumors, particularly in the parotid gland, primarily affecting women between the ages of 40 and 60. However, its occurrence in the trachea is very rare. This article reports the case of a 48-year-old woman presenting with progressive dyspnea and weight loss, initially suspected of having a pulmonary embolism. A chest CT scan revealed a nearly circumferential tracheal lesion with 2 nodules partially obstructing the tracheal lumen. Histological analysis confirmed the presence of a pleomorphic adenoma of the "salivary gland" type. Although rare, tracheal pleomorphic adenoma should be considered in the differential diagnosis of tracheal tumors. MRI is the preferred examination for detecting tumors in the parotid gland region, offering excellent tissue differentiation. Surgery remains the treatment of choice to prevent recurrence.
多形性腺瘤（PA）是唾液腺肿瘤最常见的良性组织学类型，尤其好发于腮腺，主要影响40至60岁的女性。然而，其发生于气管的情况非常罕见。本文报告了一例48岁女性，表现为进行性呼吸困难和体重减轻，最初怀疑患有肺栓塞。胸部CT扫描显示一个几乎环绕气管的病变，有2个结节部分阻塞气管腔。组织学分析证实存在“唾液腺”型多形性腺瘤。尽管罕见，但在气管肿瘤的鉴别诊断中应考虑气管多形性腺瘤。MRI是检测腮腺区域肿瘤的首选检查方法，具有出色的组织分辨能力。手术仍然是预防复发的首选治疗方法。
