Well differentiation AdenocarcinomaBetween 75 and 80 of all endometrial carcinomas are adenocarcinomas, and the prognosis depends on stage, histologic grade, and extent of myometrial invasion. Grade I tumors are highly differentiated adenocarcinomas, grade II tumors contain some solid areas, and grade III tumors are largely solid or undifferentiated. Adenocarcinoma with squamous differentiation is seen in 10 of patients; the most differentiated form is known as adenoacanthoma, and the poorly differentiated form is called adenosquamous carcinoma. Other less common pathologies include mucinous carcinoma 5 and papillary serous carcinoma 10.
