ABSTRACT
Herein we report a rare case of mucinous bronchioloalveolar carcinoma (BAC) associated with a solitary bronchiectatic cyst in a 29-year-old man. The patient presented with hemoptysis and had a history of pulmonary tuberculosis. Chest radiographs and computed tomography revealed a well-circumscribed, thin-walled cavitary lesion in the right upper pulmonary lobe. Gross examination of a lobectomy specimen showed a bronchiectatic cavity and a fungus ball within it. There were also several ill-defined small gray-white nodules around the cyst, nodules that were mucinous BAC. On microscopy, they were composed of columnar tumor cells along the intact alveolar walls in a single layer.
