| ABSTRACT |
|
Mucous gland adenoma (MGA) of the lung is an uncommon, benign tumor that histologically resembles the mucus-secreting component of the tracheobronchial gland. The majority arises within the main, lobar or segmental bronchi.
MGA presenting as a peripheral lung mass is extremely rare.
We herein report a case of MGA that uniquely arose from the peripheral territory of the superior segmental bronchus of the left lower lobe in a 73-year-old male. Chest computed tomography showed a 13 mm-sized, subpleural nodule, which was easily enucleated by video-assisted thoracotomy. The mass was round and gray-tan in color with mucoid material.
The tumor was composed of cysts, tubules, and glands lined by bland columnar, cuboidal or flattened, mucus secreting cells. |
