ABSTRACT
OBJECTIVE@#To study the correlation between ultrastructure of lymphatic capillary in pericancerous tissue and neck lymph node metastasis in laryngeal carcinoma.@*METHOD@#Transmission electronic microscope was applied to observe and compare ultrastructure of lymphatic capillary in 8 normal laryngeal epithelial tissue and 12 pericancerous tissue of laryngeal cancer.@*RESULT@#Lymphatic capillary of pericancerous tissue was significantly dilated compared with normal laryngeal tissue. A large amount of endothelial cell junction was open and devoid of basement membrane. Some endothelial cells of lymphatic capillary were destroyed or broken completely.@*CONCLUSION@#Ultrastructure of lymphatic capillary in pericancerous tissue is an important factor of laryngeal cancer metastasis through lymphatic system. This research offers theoretic basis for laryngeal carcinoma metastasis mechanism and prevention.
