# Tracheobronchial endoluminal hamartochondroma resected via rigid bronchoscopy: 2 case reports of a rare entity

## TL;DR

This paper presents two rare cases of tracheobronchial endoluminal hamartochondroma successfully treated with rigid bronchoscopy and laser.

## Contribution

The novel contribution is the successful use of rigid bronchoscopy with laser for resecting a rare benign tumor in the airway.

## Key findings

- Rigid bronchoscopy with diode laser effectively resected tracheobronchial endoluminal hamartochondroma in two patients.
- Only one patient had a small stable tumor residue post-surgery.
- Flexible bronchoscopy is recommended for follow-up after resection.

## Abstract

Tracheobronchial endoluminal hamartochondroma (HC) is a rare benign tumor, most frequently diagnosed in individuals between the sixth and seventh decades of life. The clinical presentation is usually very noisy. Here, we report two interesting cases. The first patient is a 58-year-old man who was wrongly treated for chronic obstructive pulmonary disease. HC was in the lower third of the trachea. The second patient is a 43-year-old man with a history of bronchiectasis and right lower lobectomy. HC was in the middle lobe bronchus. The resection via rigid bronchoscopy with diode laser was successful without any complications. Only one patient keeps a small stable tumor residue. The rigid bronchoscopy with laser-application in tracheobronchial endoluminal HC is safe and effective. Flexible bronchoscopy is important during the follow-up.
