Decidualization is a process that results in significant changes to cells of the endometrium in preparation for, and during, pregnancy. This includes morphological and functional changes (the decidual reaction) to endometrial stromal cells (ESCs), the presence of decidual white blood cells (leukocytes), and vascular changes to maternal arteries.
H&E stain Low magnification micrograph of decidualized endometrium. H&E stain. The endometrium consists of a single layer of columnar epithelium plus the stroma on which it rests. The stroma is a layer of connective tissue that varies in thickness according to hormonal influences.
An endometrial polyp or uterine polyp is a mass in the inner lining of the uterus. [1] They may have a large flat base or be attached to the uterus by an elongated pedicle (pedunculated). [2] [3] Pedunculated polyps are more common than sessile ones. [4] They range in size from a few millimeters to several centimeters. [3]
Dr. Jessica Kingston, clinical professor ob-gyn at UC San Diego Health, tells Yahoo Life that a decidual cast is “a layer of tissue that is shed from the endometrium — lining of the uterus ...
Decidual cells are also thought to control the invasion of the endometrium by trophoblast cells. [ 2 ] Experimentally, human endometrial stromal cells can be decidualized in culture by using analogs of cAMP and progesterone .
Micrograph of decidualized endometrium due to exogenous progesterone. H&E stain. The decidua has a histologically-distinct appearance, displaying large polygonal decidual cells in the stroma. These are enlarged endometrial stromal cells, which resemble epithelium (and are referred to as "epithelioid").
Endometrial Stromal Nodule. An endometrial stromal nodule is a noninfiltrative, circumscribed proliferation of endometrial stromal cells and is a benign subtype of endometrial stromal tumor. The appearance of the cells is identical to normal endometrial stromal cells. This can only be differentiated from low-grade endometrial stromal sarcoma by ...
Endometrial hyperplasia is a condition of excessive proliferation of the cells of the endometrium, or inner lining of the uterus.. Most cases of endometrial hyperplasia result from high levels of estrogens, combined with insufficient levels of the progesterone-like hormones which ordinarily counteract estrogen's proliferative effects on this tissue.
