Research Abstract |
Blood capillary vessels within the epithelial zone(IEBVs) of oral borderline malignancies including epithelial dysplasia and carcinoma in-situ(CIS) were examined by immunohistochemistry for CD31 and type IV collagen. IEBVs increased in number significantly in CIS. It was revealed that narrow band imaging(NBI), that is established to visualize abnormal microvascular patterns was a effective tool for differential diagnosis of oral borderline malignancies and decision of a adequate safety margin.
