Hello and welcome to HCM,
The description that you have mentioned is the microscopic findings of endometrial biosy, curettings.
These microscopic findings suggest presence of decidua.
Decidua is the tissue which lines the uterine wall during pregnancy
Thus, these findings indicate the presence of pregnancy.
The glandular structures are the endometrial glands which show Arias Stella reaction.
All these changes suggest a gestation/ pregnancy.
However, the pregnancy can be uterine or at some other site like fallopian tube
the presence of villi is confirmatory of pregnancy.
These changes can also occur under the influence of hormones (progesterone
Further you need to consult your gynaecologist for clinical correlation.
Thanks and take care.
