A prompt surgical evaluation and, if necessary, surgical resection are recommended.
Pulmonary adenomas are a group of benign tumors originating from the bronchial mucous glands and adenoidal epithelium, but have a tendency to become malignant. They often occur between 30 and 50 years of age and have a similar incidence in men and women. Bronchial adenoma is diagnosed at an earlier age than bronchial carcinoma. There are different symptoms depending on the location of tumor growth. When it occurs in the large airways, patients may have irritating dry cough and repeated sputum blood. If the tumor increases in size, localized obstructive emphysema may occur. If the lumen is completely obstructed, pulmonary atelectasis may occur. Pneumonia, lung abscess or bronchiectasis may occur as a result of secondary infection in the distal lung of the obstruction. Because adenomas are benign, symptoms are long-lasting. If malignant metastases occur, the symptoms are similar to those of other cancer metastases. Therefore, close follow-up and dynamic evaluation should be performed, and if accompanied by significant clinical symptoms, surgical removal is recommended under the assessment of a surgeon. In addition, it is important to be vigilant in improving the diagnosis of the disease and to avoid delays.
