Mucous gland adenoma of the trachea: case report and literature review

Adenoma arising from bronchial mucous glands is extremely rare. Such tumors are truly benign, in contradistinction to other tumors previously grouped under the term "bronchial adenoma." We present the first case reported of mucous gland adenoma arising in the trachea. This case was initially misdiagnosed as asthma, a common error with obstructing tracheo-bronchial lesions.
