Correlation between blood and lymphatic microvascular density and cell proliferation in mouth floor and tongue squamous cell carcinoma

Floor of mouth SCC cases was morphologically more aggressive than tongue cases; however, in tongue carcinomas a greater quantity of lymphatic vessels could represent potential ways for locoregional cell dissemination of the neoplastic cells, independent of histological grading. Blood vascularization presented correlation with cell proliferation in intraoral squamous cell carcinoma and could be useful in the prognostic assessment of this neoplasm.
