Whistling Lipoma: Bronchial Obstruction Caused by a Lipoma.

Lipomas are extremely common benign tumors that occur in a variety of locations. However, lipomas in the bronchus are exceptionally rare and account for a very small number of all bronchial tumors. Diagnosis of an endobronchial lipoma can be challenging at times, as they may present with overlapping symptoms of central airway obstruction, pneumonia, or dyspnea. We present an 82-year-old male with a 40-pack-year history of smoking who presented with recurrent pneumonia and signs of airway obstruction. Imaging studies showed an obstructive lesion. The biopsy sample revealed adipose cells. Eventually, the lesion was successfully resected. The surgical specimen ruled out malignancy and confirmed the diagnosis of lipoma. Timely identification and differentiating a malignant lesion from benign lesions, like lipoma, is crucial to management.
