Misdiagnosed case of bronchial carcinoid presenting with refractory dyspnoea and wheeze: a rare case report and review of literature.

A 59-year-old male smoker presented with persistent wheezing and occasional coughing that had been ongoing for two years and had been unsuccessfully treated with an inhalational β2 agonist, an anticholinergic and an inhalational steroid in the last year. On clinical examination, a left-sided wheeze was detected. The initial chest X-ray was normal. A computed tomography (CT) scan of thorax demonstrated a mass lesion in the left main bronchus. On subsequent bronchoscopy, an endobronchial polypoid mass was detected in the left main bronchus, completely occluding the bronchial lumen. A biopsy taken from the mass revealed features of bronchial carcinoid. Bronchial carcinoid can present uncommonly with wheezes, resulting in misdiagnosis as bronchial asthma or chronic obstructive pulmonary disease (COPD). If an asthma or COPD patient does not respond to conventional therapy, a CT scan and subsequent bronchoscopy is warranted.
