Solitary atypical adenomatous hyperplasia in the lung of a 17-year-old man with spontaneous pneumothorax.
We report here a case of solitary atypical adenomatous hyperplasia (AAH). A 17-year-old non-smoker man developed spontaneous pneumothorax, and computed tomogram scanning of his chest revealed a ground-glass opacity measuring 5 x 5 mm in the right lung with no change in its size for the next 7 months. To exclude the possibility of pulmonary neoplasia, he underwent partial pulmonary resection. The postoperative pathologic diagnosis was AAH. The present case is very exceptional for AAH because of the patient's young age and non-association with pulmonary carcinoma. The postoperative 23-month follow-up was uneventful.
