기관에서 발생한 점액선 선종 1예

Mucous gland adenoma of the bronchus is a rare benign tumor arising from the bronchial mucous gland. It accounts for less than 0.5% of all lung tumors. In adults, tracheal tumors are most often malignant. Among benign tumors arising in the trachea, mucous gland adenoma of the trachea is extremely rare. First case was reported by Ferguson and Cleeland in 1988, as "Mucous gland adenoma of the trachea". Microscopic study shows it to arise from normal submucosal mucous glands forming glandular or tubular structures composed of mucous secreting cells. Common symptoms were cough, hemoptysis, recurrent and protracted pneumonia, shortness of breath, and wheeze. Duration of symptoms before diagnosis varied from a few weeks to 10 years with prolonged symptoms being usual. Management of these tumors should be complete excision, including pulmonary resection because two instances of recurrence after local excision have been reported.
