Abstract
BACKGROUND: Endobronchial 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. CONCLUSION: This 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.
