Rosacea is common inflammatory facial dermatosis. Rosacea has variable manifestations including facial flushing, central facial erythema,

Androgens are produced throughout the body in steroid-producing organs, such as the adrenal glands and ovaries, as well as in other tissues, like the skin. Several androgens are found normally in women, including dehydroepiandrosterone (DHEA), dehydroepiandrosterone-sulfate (DHEA-S), testosterone, dihydrotestosterone (DHT), and androstenedione. These androgens are essential in the development of several common cutaneous conditions in women, including acne, hirsutism, and female pattern hair loss (FPHL) - androgen mediated cutaneous disorders (AMCDs). However, the role of androgens in the pathophysiology of these diseases is complicated and incompletely understood. In the first article in this Continuing Medical Education series, we discuss the role of the skin in androgen production as well as the impact of androgens on the skin in women. Specifically, we review the necessary, but insufficient role that androgens play in the development of acne, hirsutism, and FPHL in women. Dermatologists face the challenge of differentiating physiologic from pathologic presentations of AMCDs in women. There are currently no dermatology guidelines outlining the indications for endocrinologic evaluation in women presenting with acne, hirsutism, and/or FPHL. We review available evidence regarding when to consider an endocrinologic work-up in women presenting with AMCDs, including the appropriate type and timing of testing.

Androgen-mediated cutaneous disorders (AMCDs) in women including acne, hirsutism, and female pattern hair loss (FPHL) can be treated with hormone-modulating therapies. In the second part of this Continuing Medical Education series, we discuss the hormone-modulating therapies available to dermatologists for the treatment of AMCDs including combined oral contraceptives, spironolactone, finasteride, dutasteride, and flutamide. Available hormone-modulating treatments utilized for each AMCDs are reviewed, along with mechanisms of androgen modulation, safety profile, contraindications, monitoring parameters, and evidence of efficacy. Medications discussed include ones that are FDA-approved for certain AMCDs as well as some that are used off-label. Despite the ubiquity of hormone-modulating therapies used for AMCDs, this review highlights the need for more rigorous studies to evaluate these therapies for acne, hirsutism, and FPHL.

The term, acquired perforating dermatoses (APD), represents a group of skin conditions that develop in adulthood and are characterized by transepidermal elimination of dermal connective tissue. This appears clinically as a papulonodule with a keratotic core. Although APD is typically associated with diabetes mellitus, chronic renal failure, and several other conditions causing generalized pruritus, there have been reports in the literature describing an association of APD with select drugs including sorafenib. We present a case of acquired perforating dermatosis in a patient with HIV and hepatocellular carcinoma undergoing treatment with sorafenib.

PURPOSE/OBJECTIVE:Washing and over-the-counter cleansers are common interventions in acne vulgaris (AV), but the clinical evidence for their benefit is poorly understood. This systematic review presents clinical studies of washing and cleanser efficacy in acne vulgaris to guide treatment recommendations of dermatologists. MATERIALS AND METHODS/METHODS:We surveyed English-language articles indexed in MEDLINE (1951-March 2017) and EMBASE (1974-March 2017). Articles were required to be prospective studies of a single over-the-counter cleanser or washing intervention in AV with an objective AV outcome measurement published in a peer-reviewed journal. RESULTS AND CONCLUSIONS/CONCLUSIONS:Fourteen prospective studies representing 671 participants were included in this review. Modalities investigated included face washing frequency, true soap/syndet cleansing bars, antiseptic cleansers, alpha and beta-hydroxy (i.e. salicylic) acid cleansers, and several proprietary formulations. Given the low number of well-performed clinical studies of cleansers and washing, it is difficult to formulate reliable recommendations. We hope that our findings highlight the necessity of further investigation in this area.

Acne is the most common skin condition in the United States, affecting 50 million Americans annually. The disease's severity can range from mild to severe, with approximately 20% of people with acne experiencing moderate to severe disease.
