A rare mimic of adult‐onset asthma: Case report and review of the literature

Abstract

AbstractAdult‐onset asthma is extremely variable in its phenotypic presentation and has gained notoriety for the overall poorer treatment outcomes even on standard asthma therapy. Tracheal tumours are rare but when present, exhibit asthma‐like phenomenon in adult patients posing great diagnostic challenges. We report two adult patients with tracheal adenoid cystic tumours who were initially treated for adult‐onset asthma. Patient 1, a 45‐year‐old man was diagnosed and managed for adult‐onset asthma over a 12 months period without satisfactory control of his symptoms. Following a late episode of hemoptysis, a chest Computed Tomography (CT) scan done revealed an occluding tracheal tumour. Patient 2 is a 28‐year‐old female who was diagnosed with adult‐onset asthma for over 2 years with poor symptom control despite optimal asthma therapy. She developed cough‐induced subcutaneous emphysema for which a chest CT scan revealed a tracheal mass. The patient had surgery with incomplete resection of tumour and adjuvant radiotherapy.
