Squamous Cell Carcinoma of the Lung Spreading Along the Alveolar Walls With a Bubblelike Appearance on HRCT.

On health examination, a nodular opacity of size of 25 mm was detected in a 54-year-old man. High-resolution computed tomography scans showed irregular-shaped ground glass opacity with bubble-like appearance in the right lung. The low-magnified histological findings after right upper lobectomy demonstrated squamous cell carcinoma that progressed along the alveolar septum and resembled the growing pattern of bronchioloalveolar carcinoma.
