| Research Abstract |
The aim of this study is to clear three-dimensional morphological changes of lymphatic vessels in a progression of BAC. In the normal alveolar region, they straightly elongated without bifurcation and most of them were compressed. In the central portion of the fibrotic lesion, the density of lymph vessels was higher and the lumens were wider. The lymph vessels morphologically changed to a tank. As the BAC advances forming central fibrosis, the volume ratio of the lymph vessels to the whole one of the cancer will become larger, and probability of carcinoma cell invasion to the lymph vessels will increase.
