Venn diagram of patients included in the present study. Among the 559 cases of lung adenocarcinoma, 104 cases had MPC. Nineteen cases had SMPC (SMPC(+) tumors, the area enclosed by continuous line), and 99 had AMPC (AMPC(+) tumors, the area enclosed by dotted line). A mixture of SMPC and AMPC was observed in 14 patients, SMPC without AMPC in 5 and AMPC without SMPC in 85. MPC, micropapillary component; SMPC, stromal micropapillary component; AMPC, aerogenous micropapillary component.
