Figure 1 Computed tomography (CT) scan. (a) There was a small pure ground-glass nodule (GGN) on the left upper lobe and with a diameter of 12mm and a CT value of −727HU in June 2007. (b) A small solid area (5mm in diameter) appeared with a CT value of +19HU in January 2011. (c) The solid density area had enlarged, and its CT value was +55HU.

Figure 2 Microscopic immuohistochemical findings of the tumor. The adenocarcinoma component contained minimal invasive adenocarcinoma. The tumor was positive for Napsin A at adenocarcinoma component and positive for NCAM (CD56), CgA and SPN at the small cell carcinoma of the lung component.
