title: [Epithelial dysplasia and invasive carcinoma of oral cavity showing punctation and atypical vessels].
abstract: We have experienced epithelial dysplasia and invasive carcinoma of oral cavity, showing punctation and mosaic like atypical vessels confirmed by usual photographing. Case 1: 42-year-old man. After resection of tongue leukoplakia, the punctation appeared in the distal region of resected wound. Pathological findings were epithelial dysplasia, and expansion of capillaries in the stromal papillae were close to the surface. Case 2: 55-year-old woman. Punctation and mosaic like atypical vessels were recognized in the buccal mucosa, extending from the gingival carcinoma. Pathological findings were epithelial dysplasia and carcinoma in situ in punctation, and early invasive carcinoma in mosaic. There were irregularly expanded capillaries in the stromal papillae being close to the surface at both mosaic and punctation area. Although punctation, atypical vessels and mosaic are the colposcopic findings of uterine cervical cancer, these findings may become diagnostic point of early oral cancer.
