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 ...
Endometrial Topography Functional Category Treatment Benign endometrial hyperplasia: Diffuse: Hormone (estrogen) Effect: Hormonal therapy EIN, Endometrial Intraepithelial Neoplasia: Focal progressing to diffuse (clonal) Precancer: Hormonal or surgical Endometrial Adenocarcinoma: Focal progressing to diffuse (clonal) Cancer: Surgical stage-based
Endometrial hyperplasia – Hyperproliferation of the endometrium, usually in response to unopposed estrogen stimulation in the setting of polycystic ovary syndrome or exogenous administration of hormones. Atypical endometrial hyperplasia may represent an early neoplastic process which can lead to endometrial adenocarcinoma. [20]
An atypical hyperplasia is one with visible abnormalities in the nuclei. Pre-cancerous endometrial hyperplasias are also referred to as endometrial intraepithelial neoplasia. [41] Mutations in the KRAS gene can cause endometrial hyperplasia and therefore Type I endometrial cancer. [37] Endometrial hyperplasia typically occurs after the age of ...
Arias-Stella reaction, also Arias-Stella phenomenon, is a benign change in the endometrium associated with the presence of chorionic tissue. [1] Arias-Stella reaction is due to progesterone primarily. Cytologically, it resembles a malignancy and, historically, it was misdiagnosed as endometrial cancer. [1]
(E): endometrial atypical hyperplasia (Left: HE × 10) and endometrial atypical cells (Right: HE × 200) (F) endometrial carcinoma (Left: HE × 400) and endometrial cancer cells (Right: HE × 400). Chorionic tissue can result in marked endometrial changes, known as an Arias-Stella reaction , that have an appearance similar to cancer . [ 15 ]
This case closely resembles normal surface endometrial epithelium of the uterus. Histopathology of the typical features of an ovarian serous borderline tumor : Hierarchical branching, exfoliated cell clusters, calcifications, up to moderate atypia, and pseudostratified, crowded epithelium with hobnailing.
Cystic hyperplasia of endometrium: Micrograph showing cystic hyperplasia of endometrium. Cystically dialated glands are lined by proliferative type of epithelium. Stroma also resembles proliferative phase. No atypia is seen in the cells. Category: Histopathology of hyperplasia endometrium: Neuroblastoma
