The tumors showed 12 cases were moderate to high differentiate adenocarcinoma, 4 cases were low differentiated adenocarcinoma.

The result showed that the surface of highly pulmonary adenocarcinoma cells is covered with irregular microvilli and poorly differentiated adenocarcinoma cells is covered with irregular microfoldings.
