Most areas are atypical complex hyperplasia.  A few foci show villoglandular pattern (for example photo #6) which is highly suggestive of a well diffentiated endometroid adeno.  You should submit all the endometrium together with some myometrium.  If no worse areas are identified, i would phrase like:

Small foci of well differentiated endometrial adenocarcinoma, endometroid type, arising in atypical complex hyperplasia.

 • a confluent glandular pattern in which individual
glands, uninterrupted by stroma, merge and create a
cribriform pattern;
• an extensive papillary pattern; and
• an irregular infiltration of glands associated with an
altered fibroblastic stroma (desmoplastic stromal
response).
