With menopause, circulating levels of 17β-estradiol (E2) markedly decrease. E2-based hormone therapy is prescribed to alleviate symptoms associated with menopause. E2 is also recognized for its beneficial effects in the central nervous system (CNS), such as enhanced cognitive function following abrupt hormonal loss associated with ovariectomy. For women with an intact uterus, an opposing progestogen component is required to decrease the risk of developing endometrial hyperplasia. While adding an opposing progestogen attenuates these detrimental effects on the uterus, it can attenuate the beneficial effects of E2 in the CNS...

Ovarian hyperthecosis (OH) is characterized by the presence of abundant luteinized theca cells in ovaries that secret androgen. It typically presents as severe hyperandrogenism and/or virilization in postmenopausal woman. Here we describe a 66-year old woman with presentation of severe hirsutism, alopecia, clitoromegaly and laboratory finding of significantly elevated serum total testosterone concentration and hyperinsulinemia. Performed imaging studies revealed normal sized, homogeneous ovaries, signs of endometrial hypertrophy and normal adrenal glands...

OBJECTIVE: Abnormal uterine bleeding is one of the most common clinical problems in gynaecological practice and is an indicator of various underlying disorders. An endometrial biopsy should be done in all women over 35 years with AUB to rule out endometrial cancer or pre-malignant lesion and to initiate treatment. However, wide range of histological patterns on endometrial biopsy offer a diagnostic challenge to practicing pathologists. The objective of this study was to determine histological patterns of endometrium in postmenopausal women with abnormal uterine bleeding...

Levonorgestrel intrauterine systems (LNG-IUS) represent a modern therapy for an array of preexisting gynecological conditions, though they were first marketed in Finland in 1990. However, there are countries in which their use is extremely limited by social and cultural factors. This manuscript describes the possible reasons for this misuse, taking in consideration the clinical noncontraceptive benefits of intrauterine levonorgestrel in routinary practice. Medical diseases in which LNG-IUS represent a treatment include abnormal uterine bleeding, iron-deficiency anemia, endometrial hyperplasia, uterine fibroids, adenomyosis, endometriosis, and coagulopathies...

OBJECTIVE: Atypical polypoid adenomyomas (APAs) are endometrial, non-malignant, focal, and non-invasive lesions that are intriguing for their histological resemblence to invasive endometrioid adenocarcinoma or malignant mixed Müllerian tumor. The aim of this study was to present our clinical experience, regarding the reproductive outcome, the recurrence rate, and the association with hyperplasia and cancer, in a small series of patients with APA. STUDY DESIGN: Retrospective case series of patients treated for APA in a single private hospital setting from 1998 to 2016...

PURPOSE: Excess circulating insulin may contribute to endometrial cancer (EC) development; studies suggest increased risk of EC associated with type 2 diabetes. We investigated whether gestational diabetes is associated with increased risk of EC and its precursor, endometrial hyperplasia (EH). METHODS: We conducted a population-based, case-control study of women in Washington State. Cases were women with a hospital discharge record indicating the presence of EH/EC who could be linked to a prior delivery hospitalization or birth record from 1987 to 2013 (n = 593)...

INTRODUCTION: Young women with endometrial intraepithelial hyperplasia or low-grade endometrial carcinoma are potential candidates for conservative fertility sparing therapy utilizing progesterone rather than hysterectomy. High-dose progesterone treatment is associated with 55-80% initial response but high relapse rates. Using aromatase inhibitors in conjunction with high-dose progesterone has largely been unstudied. CASE DESCRIPTIONS: Three obese premenopausal women with endometrial cancer failed to respond to oral or intrauterine progesterone as first line therapy...

Although progestin has been used to treat endometrial hyperplasia and endometrial carcinoma (EC), its therapeutic efficacy is limited. In order to improve this, the underlining mechanisms of the effects of progestin need to be elucidated in more detail. In the present study, we examined the involvement of mitogen-inducible gene-6 (MIG6), a negative regulator of the EGF receptor, in the progestin-mediated growth suppression of endometrial epithelia. The immunohistochemical expression of MIG6 was elevated in the early to mid-secretory phases of normal endometrium and also with endometrial hyperplasia after medroxyprogesterone acetate (MPA) therapy...

Endometrial polyps are localized overgrowth of endometrial glands and stoma through the uterine cavity. They are associated with postmenopausal bleeding, infertility and menorrhagia and are affected by unbalanced oestrogen therapy or increased frequency of tamoxifen exposure. We report a case of giant endometrial polyp in postmenopausal female without vaginal bleeding and hormone or drug use. A 65-year-old, postmenopausal female P3L2 with hypertension and Diabetes Mellitus (DM) came for routine health check-up...

Endometrial cancer (EC) is the most common malignancy of the female genital tract in the developed countries. In Poland, EC incidence increased from 3.496 to 5.251 between 2000 and 2011, with 5.251 new cases were diagnosed in 2011 alone, and this upward trend is expected to continue. There are two types of endometrial cancer: estrogen- related type I (approximately 80% of the cases) and unrelated to estrogen type II. Type I includes adenocarcinomas which grow slowly, have better prognosis, superficially infiltrate the myometrium, originate from endometrial hyperplasia without atypia, and occur before and after menopause...

Elizabeth R Burton, Joel I Sorosky
An update on the current epidemiology and a review of the risk factors of cervical and endometrial cancers are discussed. Cervical cancer prevention with a focus on human papillomavirus vaccination and cervical cancer screening is reviewed, emphasizing the new focus of less frequent intervention in an effort to maintain high rates of early detection of disease while decreasing unnecessary and anxiety-provoking colposcopies, biopsies, and excisional procedures. The replacement of traditional endometrial hyperplasia terminology with more relevant clinical categories, with an emphasis on the introduction of endometrial intraepithelial neoplasia, is presented...

OBJECTIVE: The 2014 Bethesda System recommends that benign-appearing endometrial cells (BECs) in routine Pap tests should be reported in patients aged ≥45 years. This is a change from previous guidelines to report BECs in women ≥40 years of age. BECs are reported to have 1% chance of endometrial lesion on follow-up. This study tests whether the new threshold may increase the specificity of the test for the detection of clinically significant endometrial lesions. STUDY DESIGN: After institutional review board approval, 1,177 BECs, reported during an 8-year study period in patients aged ≥40 years, were retrieved from 672,000 routine ThinPrep Pap tests...
