Abstract

We report a case of multiple atypical adenomatous hyperplasia (AAH) associated with synchronous multiple primary bronchioloalveolar carcinomas (BACs). A 58-year-old man was visited for bronchial asthma. A chest computed tomography (CT) scan revealed small, multiple nodules with ground glass attenuation (GGA) throughout both lungs, predominantly in the upper lobes. A high resolution CT (HRCT) scan disclosed well-defined nodules with uniform GGA. Thoracoscopic wedge lung biopsy confirmed the diagnosis. The patient was treated with chemotherapy and had stable disease for two years. It is important to recognize that multiple AAH associated with multiple BACs can present as diffuse, well-defined nodules with uniform GGA on HRCT.<br>(Internal Medicine 41: 474-477, 2002)
