A rare case of endo-bronchial lipoma presenting with vague cardiac symptoms

Endobronchial lipoma is an extremely rare benign tumor, accounting for 0.1%-0.5% of all lung tumors. This case report presents a patient diagnosed with endobronchial lipoma, a condition that can lead to significant bronchial obstruction and subsequent parenchymal damage. Patients usually exhibit symptoms including cough, dyspnea, and recurrent respiratory infections, which initially mimic more common pulmonary conditions such as chronic obstructive pulmonary disease. However, in our case patient presented with non-specific cardiac symptoms. Diagnosis was confirmed through bronchoscopy, revealing a well-circumscribed mass obstructing the bronchus. Due to severe parenchymal inflammation, treatment involved left-sided thoracotomy and upper lobectomy which successfully relieved the obstruction and alleviated the patient's symptoms. Histopathological examination identified the tumor as a lipoma. This case underscores the importance of considering endobronchial lipoma in differential diagnoses for patients with unexplained cardiac or respiratory symptoms, as early detection and treatment can prevent significant complications.
