Estradiol (E2) is a medication and naturally occurring steroid hormone. It is an estrogen and is used mainly in menopausal hormone therapy and to treat low sex hormone levels in women. It is also used in hormonal birth control for women, in hormone therapy for transgender women, and in the treatment of hormone-sensitive cancers like prostate cancer in men and breast cancer in women, among other uses. Estradiol can be taken by mouth, held and dissolved under the tongue, as a gel or patch that is applied to the skin, in through the vagina, by injection into muscle or fat, or through the use of an implant that is placed into fat, among other routes.Side effects of estradiol in women include breast tenderness, breast enlargement, headache, fluid retention, and nausea among others. Men and children who are exposed to estradiol may develop symptoms of feminization, such as breast development and a feminine pattern of fat distribution, and men may also experience low testosterone levels and infertility. Estradiol may increase the risk of endometrial hyperplasia and endometrial cancer in women with intact uteruses if it is not taken together with a progestogen such as progesterone. The combination of estradiol with a progestin, though not with oral progesterone, may increase the risk of breast cancer. Estradiol should not be used in women who are pregnant or breastfeeding or who have breast cancer, among other contraindications.Estradiol is a naturally occurring and bioidentical estrogen, or an agonist of the estrogen receptor, the biological target of estrogens like endogenous estradiol.
Extramammary Pagets Disease (EMPD) is a rare and slow-growing malignancy which occurs within the epithelium and accounts for 6.5% of all Pagets disease. The clinical presentation of this disease is similar to the characteristics of mammary Pagets disease (MPD). However, unlike MPD, which occurs in large lactiferous ducts and then extends into the epidermis, EMPD originates in glandular regions rich in apocrine secretions outside the mammary glands. EMPD incidence is increasing by 3.2% every year, affecting hormonally-targeted tissues such as the vulva and scrotum. In women, 81.3% of EMPD cases are related to the vulva, while for men, 43.2% of the manifestations present at the scrotum.The disease can be classified as being either primary or secondary depending on the presence or absence of associated malignancies. EMPD presents with typical symptoms such as scaly, erythematous, eczematous lesions accompanied by itchiness. In addition to this, 10% of patients are often asymptomatic. As a consequence, EMPD has high rates of misdiagnoses and delayed diagnoses. There are a variety of treatment options available, but most are unsuccessful. If caught early and treated, prognosis is generally good. Presentation
Patients with EMPD present with typical symptoms, similar to MPD, such as severe itchiness (also called pruritus), rash, plaque formation, burning sensation, pain and tenderness. These symptoms are often confused for dermatitis or eczema. 10% of patients are asymptomatic resulting in delayed diagnosis. In rare cases bleeding can also be seen. Disease of the vulva
Vulvar Pagets disease affect women and presents as erythematous (red), eczematous lesions.
