Multiple endo bronchial lipoma: a rare case report

Area of Science:

• Pulmonology
• Oncology
• Pathology

Background:

• Endobronchial lipomas are exceptionally rare benign tumors, typically solitary and located in the upper tracheobronchial tree.
• Existing literature suggests endobronchial lipomas occur singly per patient.

Observation:

• A 52-year-old male smoker presented with cough and dyspnea.
• Computed tomography (CT) revealed two distinct low-density endobronchial masses in the left main bronchus and left lower lobe.
• Bronchoscopic intervention successfully resected both neoplasms, confirmed histopathologically as lipomas.

Findings:

• This case demonstrates the possibility of multiple endobronchial lipomas occurring simultaneously in a single patient.
• Both proximal (left main bronchus) and distal (left lower lobe) locations were affected.

Implications:

• The findings expand the understanding of endobronchial lipoma presentation, indicating they can be multifocal.
• This challenges previous assumptions about the solitary nature of these rare tumors.
• Highlights the importance of thorough examination for multiple lesions in suspected endobronchial lipoma cases.
