Abstract

Lipoma is a common neoplasm in soft tissues. However, an intrapulmonary lipoma is a rare benign tumor. Patients with a bronchial lipoma might have a malignant potential related to their smoking history due to the case reports of lung cancer accompanied with lipoma. Endobronchial lipoma can cause irreversible parenchymal lung damage if not diagnosed and treated early. Therefore, it should initially be treated by fiberoptic bronchoscopy or surgery depending on the status of distal parenchymal lung damage. Bronchiolitis obliterans with organizing pneumonia (BOOP) is a pathological syndrome that is defined by the presence of buds of granulation tissue consisting of fibroblasts and collagen within the lumen of the distal air spaces. BOOP is caused by drug intoxication, connective tissue disease, infection, obstructive pneumonia, tumors, or an unknown etiology. We encountered a 58 year-old male patient with endobronchial lipoma, causing the collapse of the right middle and lower lobes, and BOOP due to obstructive pneumonia.
