INTRODUCTION AND IMPORTANCE: Although pleomorphic adenoma is the most common type of parotid gland tumor, its occurrence in the trachea is rare. Here, we describe a successfully resected pleomorphic adenoma of the trachea in a woman with severe respiratory failure that had been preoperatively misdiagnosed as asthma.
CASE PRESENTATION: A 69-year-old woman presented to the emergency department with symptoms of worsening dyspnea and subsequent loss of consciousness. She had a history of progressively worsening wheezing and stridor over the course of 2-years and had been diagnosed with asthma. Arterial blood gas sample analysis indicated type II respiratory failure. A chest computed tomographic scan revealed a tumor in the trachea, which was almost completely obstructing the lower tracheal lumen. The tumor was located just above the carina. To alleviate airway constriction and achieve complete resection, carinal resection with reconstruction was performed. The postoperative diagnosis was pleomorphic adenoma of the trachea.
CLINICAL DISCUSSION: Pleomorphic adenoma is a rare tracheal tumor that may present with obstructive airway symptoms that mimic asthma.
CONCLUSION: Tracheal tumors should be considered in patients with chronic respiratory symptoms that do not improve with medication.
