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.
Atypical hyperplasia is a high-risk premalignant lesion of the breast. It is believed that atypical ductal hyperplasia (ADH) is a direct precursor for low-grade mammary ductal carcinoma , whereas atypical lobular hyperplasia (ALH) serves as a risk indicator.
Hyperplasia of the breast – "Hyperplastic" lesions of the breast include usual ductal hyperplasia, a focal expansion of the number of cells in a terminal breast duct, and atypical ductal hyperplasia, in which a more abnormal pattern of growth is seen, and which is associated with an increased risk of developing breast cancer.
Other tests helpful in the diagnosis include urine protein, urinalysis, serum albumin, and serum lipids. [2] A clinical picture of proteinuria, low blood protein levels (albumin, antibodies), and high blood cholesterol would support a diagnosis of FSGS, although these do not help to distinguish between FSGS and other causes of proteinuria.

There are a number of indications for obtaining an endometrial biopsy from a non-pregnant woman: [citation needed]. Women with chronic anovulation such as the polycystic ovary syndrome are at increased risk for endometrial problems and an endometrial biopsy may be useful to assess their lining specifically to rule out endometrial hyperplasia or cancer.
Gallbladder adenomyomatosis is a benign disease of the gallbladder characterized by hyperplasia of the mucosal epithelium and smooth muscle cells inside the muscularis propria. [ 4 ] [ 5 ] [ 6 ] The excessive proliferation of epithelial cells causes the mucosa to invaginate into the muscular layer lining the gallbladder wall, resulting in ...
Angiolymphoid hyperplasia with eosinophilia (also known as: [1] "Epithelioid hemangioma," "Histiocytoid hemangioma," "Inflammatory angiomatous nodule," "Intravenous atypical vascular proliferation," "Papular angioplasia," "Inflammatory arteriovenous hemangioma," and "Pseudopyogenic granuloma") usually presents with pink to red-brown, dome-shaped, dermal papules or nodules of the head or neck ...
The cells of an EIN lesion are genetically different than normal and malignant tissues, and have a distinctive appearance under the light microscope. EIN cells are already neoplastic, demonstrating a monoclonal growth pattern and clonally distributed mutations. Progression of EIN to carcinoma, effectively a conversion from a benign neoplasm to ...
