A case of squamous cell carcinoma of the uterine cervix in which there was diffuse replacement of the almost entire endometrial surface by an intra-epithelial squamous cell carcinoma is reported. This case was 59 year old woman who came to the Hospital because of leukorrhea. Grossly the endometrial cavity was filled with pus, and the surface was irregularly grayish white, mimicking cake-ice. The entire endometrium was blocked and mapped to show features strongly suggestive of superficial extension from the cervix rather than concomittant squamous cell carcinoma of the endometrium.
