BACKGROUND: Endometrial hyperplasia (EH) is a uterine pathology representing a spectrum of morphological endometrial alterations. It is predominantly characterized by an increase in the endometrial gland-to-stroma ratio when compared to normal proliferative endometrium. The clinical significance of EH lies in the associated risk of progression to endometrioid endometrial cancer (EC) and 'atypical' forms of EH are regarded as premalignant lesions. Traditional histopathological classification systems for EH exhibit wide and varying degrees of diagnostic reproducibility and, as a consequence, standardized patient management can be challenging...

On a clinicopathological and molecular level, two distinctive types of endometrial carcinoma, type I and type II, can be distinguished. Endometrioid carcinoma, the typical type I carcinoma, seems to develop through an estrogen-driven "adenoma carcinoma" pathway from atypical endometrial hyperplasia/endometrioid intraepithelial neoplasia (AEH/EIN). It is associated with elevated serum estrogen and high body mass index and expresses estrogen and progesterone receptors. They are mostly low grade and show a favorable prognosis...

p16 is a negative regulator of cell proliferation and is considered a tumor suppressor protein. Alterations in p16 protein expression are associated with tumor development and progression. However, the p16 expression status in the peritumoral stroma has not been investigated in the endometrium. Therefore, we evaluated stromal p16 expression in different types of endometrial lesions using immunohistochemistry. Differences in the p16 expression status according to the degree of malignancy and histological type were analyzed...

BACKGROUND: Limited therapeutic guidelines exist regarding medical therapy, ideal dosing, duration of therapy, or recommendations for timing of endometrial reassessment for women with endometrial intraepithelial neoplasia (EIN) who desire fertility preservation or who are not optimal surgical candidates. We aimed to determine the effectiveness of oral progestogens (OP) versus the levonorgestrel-releasing intrauterine system (LNG IUS) in the medical treatment of EIN. METHODS: We retrospectively identified women with EIN at our institution from 2007 through 2014 and compared the outcomes of those treated with OP versus LNG IUS...

The 2014 World Health Organization (WHO) classification of uterine tumors revealed simplification of the classification by fusion of several entities and the introduction of novel entities. Among the multitude of alterations, the following are named: a simplified classification for precursor lesions of endometrial carcinoma now distinguishes between hyperplasia without atypia and atypical hyperplasia, the latter also known as endometrioid intraepithelial neoplasia (EIN). For endometrial carcinoma a differentiation is made between type 1 (endometrioid carcinoma with variants and mucinous carcinoma) and type 2 (serous and clear cell carcinoma)...

BACKGROUND: Atypical glandular cells (AGC) identified on Pap tests may be markers for potentially significant pathology. OBJECTIVES: Primarily, to correlate AGC findings at Groote Schuur Hospital (GSH, Cape Town, South Africa) with subsequent histological investigations and attempt to identify predictors of pathology relevant to the clinical management of women with a cytological diagnosis of AGC. Secondly, to compare the GSH data with data from similar international studies...

Cervical cancer is the third most commonly diagnosed cancer in women. The human wings apart-like (hWAPL) gene, which is 30,793 bp long and located on 10q23.2., is a human homologue of the WAPL gene in Drosophila melanogaster. hWAPL has the characteristics of an oncogene in uterine cervical cancer. The present study investigated the expression of the hWAPL gene in tissues, including 9 common cancers, consisting of cervical, gastric and lung cancers, liver, bladder, esophageal, endometrial, renal and rectal carcinomas, cervical intraepithelial neoplasia (CIN) and benign squamous epithelia...

Universal screening for Lynch syndrome through mismatch repair (MMR) immunohistochemistry (IHC) on tumor samples has brought to light several heterogenous MMR staining patterns. At our institution, a prospective study of universal Lynch syndrome screening using MMR IHC on 125 endometrial cancers (EC) led to the identification of subclonal loss of MMR protein expression within the tumor (n=9). We also interrogated the MMR staining patterns in MMR-deficient EC with concurrent endometrial intraepithelial neoplasia (EIN; n=14) and all mixed-type ECs (n=14) to look for concordant or discordant profiles between the various components...

BACKGROUND: Prolonged exposure to a selective progesterone receptor modulator (ulipristal acetate) in a patient with benign metastasizing leiomyoma did not result in endometrial hyperplasia or neoplasia. CASE: A woman with history of benign metastasizing leiomyoma underwent medical treatment for 5 years with ulipristal acetate. Endometrial biopsies were performed at established intervals to monitor for intraepithelial neoplasia or progesterone receptor modulator-associated endometrial changes (PAECs)...

A decade of accumulated evidence has led to significant progress and a paradigm shift in ovarian tumor pathology. Now, ovarian carcinoma is widely recognized as a heterogeneous group of neoplasms with regard to histogenesis and underlying molecular mechanisms. Ovarian carcinoma is, therefore, divided into 2 clinicopathologic groups: type 1 and type 2 tumors. Type 1 tumors arise in association with benign neoplastic conditions (adenoma-carcinoma sequence). They include endometriosis-related ovarian neoplasias, such as clear cell carcinoma and low-grade endometrioid carcinoma, which are derived from atypical endometriosis or adenofibroma, as well as mucinous carcinoma and low-grade serous carcinoma, which are commonly associated with mucinous and serous borderline tumors, respectively...
