# Wrong place at the right time, a case of primary bronchial myoepithelial carcinoma

## TL;DR

This paper presents a rare case of primary bronchial myoepithelial carcinoma and highlights the importance of early detection and surgical treatment for this uncommon lung cancer.

## Contribution

The paper contributes a detailed clinical case report of a rare lung malignancy with successful surgical management.

## Key findings

- A 78-year-old male was diagnosed with a high-grade myoepithelial carcinoma in the bronchus.
- Surgical resection with a bronchial sleeve upper lobectomy achieved complete tumor removal.
- The patient had no recurrence after follow-up imaging.

## Abstract

Primary bronchial myoepithelial carcinoma is a rare neoplasm, accounting for less than 1% of all primary lung malignancies. These tumours typically arise from submucosal tracheobronchial glands and are resistant to chemotherapy and radiotherapy, making surgical resection the preferred treatment. We present the case of a 78-year-old male who was incidentally found to have a right upper lobe endobronchial lesion following investigation for a chest infection. Imaging revealed a 3.8 cm obstructive mass in the right main bronchus. Bronchoscopic biopsy confirmed a high-grade myoepithelial carcinoma. He underwent a serratus-sparing thoracotomy with a bronchial sleeve upper lobectomy and mediastinal lymphadenectomy. The anastomosis was reinforced with a pedicled thymo-pericardial diaphragmatic fat flap. Postoperative recovery was complicated by pneumonia, delirium, and electrolyte imbalance, all of which resolved with appropriate management. Histopathology confirmed complete resection. Follow-up imaging showed no recurrence. This case underscores the importance of early recognition and meticulous surgical management in treating this rare pulmonary malignancy.
