Endoscopic resection of bronchial mucoepidermoid carcinoma in a young adult man: A case report and review of literature

Figure 1 Chest computed tomography showed an intraluminal nodule. Chest computed tomography showed a 9-mm intraluminal nodule in the bronchus intermedius with homogeneous density, well-defined margin and moderate enhancement. A: Lung window; B: Mediastinal window.

Figure 2 Interventional bronchoscopic therapy for the bronchial Mucoepidermoid carcinoma. A: Bronchoscopy revealed an endobronchial pedunculated confined to the bronchus intermedius; B: Interventional bronchoscopy was performed, and the mass was removed successfully.

Figure 3 Histopathological analysis indicated characteristics of mucoepidermoid carcinoma. The tumor is comprised of glands, tubules and cysts containing mucin separated by a fibrous stroma (Hematoxylin and eosin staining; A: ×100; B: ×400). Periodic acid schiff staining showed moderate mucin expression in the tumor mass. (C: ×400).

Figure 4 Fluorescence bronchoscopy and computed tomography during follow-up showed no relapse. A: After 3 mo, the fluorescence bronchoscopy showed normal mucosa; B: After 6 mo, chest computed tomography (CT) showed normal airways with no obstruction; C: After 19 mo, chest CT showed normal airways; D: After 2 years, chest CT showed normal airways.
