Examples of low- and high-grade endometrial endometrioid carcinomas (EEC): A) Low-grade EEC (International Federation of Gynecology and Obstetrics [FIGO] grade 1) with extensive squamous differentiation that does not qualify as “solid” for the purposes of grading; B) Low-grade EEC (FIGO grade 2) with <50% solid non-squamous growth; C) Low-grade EEC (FIGO grade 2) with <50% solid non-squamous growth; and D) High-grade EEC with a microacinar growth pattern that qualifies as “solid growth.” The presence of microacini should not be considered “glandular” for the purposes of assigning binary or FIGO grade.
