Endobronchial lipoma: a rare cause of bronchial obstruction-case report and literature review.

backgroundEndobronchial lipoma represents a rare, benign tumor that often lacks specific clinical manifestations during its initial stages, making it prone to misdiagnosis and oversight. CASE PRESENTATION: We reported a 76-year-old male patient, a long-term smoker, who was admitted to the hospital complaining of a persistent cough and expectoration lasting more than three months. A chest CT scan revealed the presence of a lipoma in the left main bronchus. The lipoma was successfully removed using electric snare resection under bronchoscopy and subsequently confirmed through pathological examination. Following the surgery, the patient experienced a substantial improvement in symptoms, with the cough and expectoration significantly reduced. Moreover, there was a notable enhancement in the local pulmonary tissue atelectasis within the left upper lobe of the lung compared to the preoperative condition.

conclusionThis comprehensive case report and concurrent literature review can deepen our understanding of endobronchial lipoma and shed light on its clinical characteristics, imaging presentations, and effective treatments.
