Tracheal myoepithelioma resected by using flexible video bronchoscope: a case report and review of the literature

Background: Tracheal myoepithelioma is a rare, low-grade malignant tumor originating from salivary gland tissue. This article presents a case of tracheal myoepithelioma without clinical symptoms, diagnosed and treated using flexible video bronchoscopy. Case Report: A 44-year-old male patient, asymptomatic for respiratory issues, was found to have a tracheal mass during a routine chest CT scan. The mass showed no significant changes over the course of one year. Upon admission, flexible video bronchoscopy revealed a coral-like neoplasm. The tumor was resected using a high-frequency electrocautery loop, followed by cryotherapy to remove residual tissue. Postoperative pathological examination confirmed the diagnosis of myoepithelioma. Three months later, follow-up flexible video bronchoscopy demonstrated good mucosal healing at the original tumor site, and chest CT showed no evidence of infiltration. The patient reported no discomfort during this period. Conclusion: Although tracheal myoepitheliomas are rare, they should be considered in the differential diagnosis of tracheal masses. Minimally invasive interventional therapy via flexible video bronchoscopy may serve as a valuable diagnostic and therapeutic approach.
