Objective To observe the ultrastructure of perilymph lymphatic vessels in tongue cancer. Methods Peritumor lymphatic capillaries were examined by transmission electron microscopy in 10 cases of tongue cancer. Results pericancerous capillary lymphatic vessels to varying degrees of expansion, and the emergence of a large number of endothelial cell connections open. Conclusions The expansion of lymphatic capillaries and the opening of endothelial junctions provide a convenient channel for tumor metastasis.
