Dermatol Ther 2021; 34:e14862. [PMID: 33571388 DOI: 10.1111/dth.14862] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Revised: 01/03/2021] [Accepted: 02/06/2021] [Indexed: 12/27/2022]
Abstract
Sebaceous glands are sebum-secreting components of pilosebaceous units. In the second of this two-part series, we review the pathologies in which sebaceous glands are primarily and secondarily implicated. They are primarily involved in steatocystoma simplex and multiplex, sebaceous gland hyperplasia, sebaceoma, sebaceous adenoma, sebaceous carcinoma, nevus sebaceus, and folliculosebaceous cystic hamartoma. Sebaceous glands are secondarily involved in acne vulgaris, seborrheic dermatitis, and androgenic alopecia. Steatocystoma multiplex is a benign congenital anomaly presenting as yellow cysts primarily on the upper body. Sebaceous gland hyperplasia is characterized by yellow, telangiectatic papules with a central dell, and it can be treated with topical retinoids or surgical excision. Sebaceoma clinically presents on the head and neck region as a skin-colored nodule and can be distinguished by immunohistochemistry. Stains used in the diagnosis of sebaceous adenoma and carcinoma include epithelial membrane antigen and adipophilin immunoperoxidase. Surgical excision is the preferred treatment for sebaceoma, sebaceous adenoma, and sebaceous carcinoma. Excision is not always indicated for nevus sebaceus. Folliculosebaceous cystic hamartoma is a relatively rare condition exhibiting both epithelial and mesenchymal components. Patients with acne vulgaris commonly present with papules of closed and open comedones displaying hypercornification. Seborrheic dermatitis presents as sharply demarcated yellow or red patches or plaques; antifungal agents, corticosteroids, and combination antifungal/anti-inflammatory therapies are common treatment modalities. As a result of hair follicle miniaturization, females with androgenic alopecia present with diffuse hair thinning, while men tend to present with balding and hairline recession.

Abstract
Acne vulgaris is a chronic inflammatory disease of the pilosebaceous unit and it is observed equally in both sexes and nearly all races. It generally begins at puberty, but the healing period is variable. There is no known etiological factor, except genetic tendency. Androgens play a very limited role in some female patients. The effects of cosmetics, foods and drinks are also discussible and too limited. There are four factors in acne pathogenesis: Increase of the sebum excretionKeratinization of infrainfundibulumBacterial colonization of the follicleInflammation It is mainly observed on the face and back, shoulders and chest. Initial lesions are comedons. Papules, pustules and cysts of severe types follow it. The most important factor in treatment is a very good patient-physician communication. Topical or systemic treatment or both can be used depending on the severity of acne. Benzoyl peroxyde, azelaic acid, AHA's antibiotics, retinoic acid and derivatives are the topical choices. For systemic treatment antibiotics are the most commonly used medicines, but isotretinoine has a very spesific place with the possibility of permanent healing. All kind of treatments need approximately six months for a good result.

Abstract
Acne Vulgaris is one of the most common skin disorders which dermatologists have to treat. It mainly affect adolescent, though may present at any age. In recent years, due to better understanding of the pathogenesis of acne, new therapeutic modalities and various permutation and combinations have been designed. In topical agents; benzoyl peroxide, antibiotics, retinoids, etc are the mainstay of treatment; can be given in combinations. While systemic therapy includes oral antibiotics, hormonal therapy, and isotretinoin, depending upon the need of patients it has to be selected. Physical treatment in the form of lesion removal, photo-therapy is also helpful in few of them. Since various old and new topical and systemic agents are available to treat acne, it sometime confuse treating dermatologist. To overcome this, panel of physicians and researchers worked together as a global alliance and task force to improve outcomes in acne treatment. They have tried to give consensus recommendation for the treatment of acne. Successful management of acne needs careful selection of anti-acne agents according to clinical presentation and individual patient needs.

Abstract
Hirsutism is an excessive body and facial hair growth in women in locations where is normally minimal or absent following a hair-male pattern. For this reason is not uncommon that hirsutism raises psychological, cosmetic and social concerns. There are many treatment modalities that can be summarised into two broad groups: pharmacologic and non-pharmacologic treatment. Until now, medical treatment has been designed to interfere with the synthesis of androgen at the ovarian or adrenal level, or inhibit the effect of androgen at the receptor level, although recent progresses test other options such as insulin modulators or ornithine decarboxylase inhibitors. Mechanical treatment includes laser hair removal, electrolysis, depilatory creams, plucking and waxing. This article presents a general overview of hirsutism treatment options.

Abstract
Acne and seborrhea (or facial oiliness) are related androgenic skin disorders which affect a high proportion of women after menarche. They can have a negative effect on psychological well-being and social life. Androgens play an important role in the pathogenesis of acne through the stimulation of sebum secretion, increasing sebaceous gland size and possibly through follicular hyperkeratinization. Conversely, estrogens decrease sebum production by suppressing gonadotropin release and androgen production and increasing sex hormone binding globulin production. One of the treatment options for these conditions is hormonal therapy, especially for women who require contraception. The effect of combined oral contraceptives in androgenic skin disorders depends on their estrogen:progestogen balance and on the antiestrogenic activity of the progestogen component. Improved understanding of what women value about oral contraceptives suggests that the choice of product should be tailored as much as possible to the individual. Several combined oral contraceptives containing new-generation progestogens (e.g. desogestrel, gestodene) or progestational antiandrogens (e.g. cyproterone acetate, chlormadinone acetate) have demonstrated efficacy in the treatment of women with acne, although comparisons between trials are difficult because of differing endpoints. Seborrhea has been less well studied, but the few studies that are available show an improvement in women with this condition using combined oral contraceptives.

Abstract
Acne is traditionally regarded as a skin disorder of the teenage years. However, recent epidemiologic studies have shown that a significant number of female patients aged >25 years experience acne. One recent community-based UK study estimated the prevalence of facial acne in adult women aged between 26 and 44 years to be 14%. It is not clear whether there is a true increase in acne in this age group or whether these patients are less tolerant of their acne and/or better informed of available therapies and so seek advice. The reasons for persistent acne are not fully understood. External factors such as use of certain cosmetics, ingestion of drugs, and endocrine abnormalities should all be considered when managing these patients. Post-adolescent acne in females can be divided into 'persistent acne', which represents a continuation of acne from adolescence into adult life, and 'late-onset' acne, which describes significant acne occurring sometimes for the first time after the age of 25 years. The clinical picture of each of these forms of acne in adult females can differ slightly from conventional adolescent disease. The course of each form is more indolent. Because of these variations, the approach to investigation and management of these cases may have subtle differences when compared with that for teenage disease. Acne treatment should aim to reduce sebum, comedogenesis, propionibacteria population, and inflammation. Treatment selection will depend on the acne grade and site as well as the patient's preference and ability to comply with therapy. Maintenance therapy plays an important role in managing this group of patients. As the response to treatment is inevitably slow, patients must be encouraged to adhere to the chosen treatment regimen. This article reviews the literature on persistent acne in women in terms of clinical presentation and possible etiologic factors, and outlines principles of therapy related to managing these cases.

Abstract
In the pathogenesis of acne, androgen hormones play a crucial role. In the treatment of acne, hormonal therapies provide valuable alternatives to standard modalities in selected women. Although numerous factors contribute to the development of acne, the requirement for androgens is absolute and is one that allows for effective treatments in women through inhibition of androgen expression. The two prerequisites for androgen expression at the level of the pilosebaceous unit are the presence of androgen in the form of either testosterone or dihydrotestosterone; and functioning androgen receptors. A third component may be the metabolism of androgen precursors to active androgens within pilosebaceous units. Hormonal treatment of hyperandrogenism (acne, hirsutism, androgenetic alopecia) such as that seen in polycystic ovary syndrome, centers on reduction of circulating androgen levels and androgen receptor blockade. Combination oral contraceptives represent the primary treatment modality for reducing circulating androgens from ovarian and, to a lesser degree, adrenal sources. Newer formulations may also have clinically significant androgen receptor blocking and 5alpha-reductase inhibiting effects. Newer oral contraceptives have high safety profiles and are used widely internationally for this purpose. Androgen receptor blockers currently in use include spironolactone, cyproterone acetate, and flutamide. Androgen receptor blockers are frequently combined with oral contraceptives to achieve optimal results in selected women. In women with adrenal hyperplasia, low-dose corticosteroids may be added to reduce adrenal androgen precursors. Inhibition of enzymes of androgen metabolism in the pilosebaceous unit remain largely investigational in the treatment of acne, although the benefit of 5alpha-reductase (type 2) inhibition is established in androgenetic alopecia in men. This article reviews the essentials of hormonal influence in acne pathogenesis, discusses the hormonal therapies most utilized in the treatment of acne, and the pre-treatment evaluation of women in whom hormonal therapies are being considered.

Abstract
In this paper we report 19 patients (14 males, 5 females; mean age 28.16 years +/- 7.68 SD) out of a series of 23 (17 males, 5 females) who developed a mood disturbance (moderate to severe depression) during treatment with finasteride, 1 mg/day orally, for androgenetic alopecia (Hamilton subtypes III-V; Ludwig subtypes I-II). Depression, which significatively impaired sociofamilial relations, sleep and eating behaviour, was associated to marked anxiety in some cases, developed after 9-19 weeks of treatment with finasteride, and promptly resolved after suspension of the drug. Two patients accepted reintroduction of the drug, and depression relapsed within 2 weeks. Depression as an adverse effect of finasteride has been reported only once. Further studies are needed to confirm our circumstantial observations, which are based on a retrospective series of patients.
