Endometrioid Adenocarcinoma of the Endometrium. At low magnification, the endometrial tumor showed a confluent glandular pattern in which individual glands merge to form a cribriform arrangement (A). at higher magnification, the confluent glands showed an absence of intervening stroma. The glands in this FIGO grade 1 tumor had round to oval nuclei with small nucleoli. The mitotic rate was low (B). Magnifications: 40× in A and 200× in B.
