形态好像够疣状癌。

Although no significant cytologic atypia is seen in the stratified squamous epithelia, well differentiated squamous cell carcinoma may appear very bland. In order to exclude this possibility, low power view of the lesion is needed. Please see if you can upload some low power view of the lesion. Thanks.

虽然复层鳞状上皮未有明显的细胞异型性，但高分化鳞癌可以表现的很温和，需要病变的低倍镜来排除高分化鳞癌的可能性。上传低倍镜图片看吧。
