Case Discussion
This case shows the natural history of a pulmonary adenocarcinoma, from its start as a ground glass nodule, demonstrating initially the pre-invasive stage from atypical adenomatous hyperplasia to adenocarcinoma in situ, and then the stage of invasive adenocarcinoma which appears as a more solid nodule.
Pathologically-proven adenocarcinoma.
