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 ...
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.
The corresponding specific proteins are expressed in the glandular and stromal cells of the endometrial mucosa. The expression of many of these proteins vary depending on the menstrual cycle, for example the progesterone receptor and thyrotropin-releasing hormone both expressed in the proliferative phase, and PAEP expressed in the secretory phase.
Low-grade endometrial stromal sarcoma consists of cells resembling normal proliferative phase endometrium, but with infiltration or vascular invasion. These behave less [3] aggressively, sometimes metastasizing, with cancer stage the best predictor of survival. The cells express estrogen/progesterone-receptors.
Adenomyosis is a medical condition characterized by the growth of cells that proliferate on the inside of the uterus (endometrium) atypically located among the cells of the uterine wall (), [2] as a result, thickening of the uterus occurs.
The prognosis for low-grade endometrial stromal sarcoma is good, with 60–90% five-year survival. High-grade undifferentiated endometrial sarcoma (HGUS) has a worse prognosis, with high rates of recurrence and 25% five-year survival. [55] HGUS prognosis is dictated by whether or not the cancer has invaded the arteries and veins.
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 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.
