A surprising diagnosis in a patient presenting with urticaria and uncontrolled asthma symptoms: A rare case of pleomorphic adenoma in the trachea

Abstract Pleomorphic adenomas are the most common benign tumors of the salivary glands. While they frequently occur in the parotid gland, they can rarely be found in the trachea. Diagnosis can be delayed as the symptoms may mimic asthma. In this case report, we present a case of pleomorphic adenoma in the trachea in a patient who had been experiencing intermittent urticaria for two years and, for the last two months, had uncontrolled respiratory symptoms despite clinical asthma treatment. This study aims to raise awareness among clinicians about differential diagnoses by highlighting the absence of asthma and urticaria symptoms following the removal of the tracheal lesion by thoracic surgery.
