=====Micro===== | |||
The sections show endometrium with pseudostratified glands and glandular dilation. On one | |||
section the gland-to-stroma ratio is increased and the glands are very focally back-to-back. Significant gland cribriforming is not identified. No nuclear atypia is apparent. Stromal desmoplasia is not identified. | |||

COMMENT: | |||
The sections show architecturally complex crowded glands with focal | |||
morular squamous metaplasia and focal cribriforming. Desmoplasia | |||
is not identified. The degree of gland confluence is not considered | |||
sufficient for the diagnosis of endometrial carcinoma. Nuclear atypia | |||
is present focally. | |||

- COMPLEX ENDOMETRIAL HYPERPLASIA WITH ATYPIA, SEE COMMENT. | |||
COMMENT: | |||
The sections show architecturally complex back-to-back glands with focal | |||
morular squamous metaplasia and cribriforming. Desmoplasia is not present. | |||
The extent, i.e. the size of the abnormality, is not considered sufficient | |||
for the diagnosis of endometrial carcinoma. | |||
</pre> | |||
====Micro==== | |||
=====CEH with atypia===== | |||
The sections show endometrium with atypical hyperchromatic, densely packed branching glands. The nuclei of the atypical glands focally are round, 2-3x the size of a lymphocyte, and have grey/translucent chromatin and small nucleoli. No papillary or cribriform changes are appreciated. No desmoplastic stroma is identified. | |||
