BACKGROUND: Non-classical congenital adrenal hyperplasia (NC-CAH) is a recessive autosomal disease caused by a deficiency of adrenal steroidogenesis enzymes. It must be distinguished from classical CAH, either simple virilising or salt-wasting, diagnosed during the neonatal period and responsible for potentially lethal disorders of sexual differentiation. NC-CAH presents a simpler and less specific clinical picture. Herein, we present two cases comprising twin girls consulting for diffuse hypertrichosis...

Pseudoxanthoma elasticum (PXE) is an autosomal recessive disorder characterized by atypical elastic fibers that causes connective tissue abnormalities of the skin, eyes, and heart, among other organs. The disorder is rare, with a classic presentation of yellow-orange cobblestone-like papules on flexural areas, lax skin, ocular degeneration, and moribund vasculature in multiple organs. There is wide variability in the presentation of the affected organs [1]. We present two sisters with classic cutaneous findings of PXE with the additional unusual findings of numerous open comedones on the neck...

BACKGROUND: Acne vulgaris (acne) is prevalent in individuals with skin of color, often with more frequent sequelae than in patients with lighter skin color. It is important to determine if there are also differences in response to medications. OBJECTIVE: This study evaluated the efficacy and tolerability of once-daily dapsone gel, 7.5% in patients with acne, stratified by Fitzpatrick skin phototype. METHODS: Data were pooled from 2 identically designed, phase 3, randomized, double-blind, vehicle-controlled studies in patients aged 12 years and older with moderate acne...

BACKGROUND: Acne vulgaris (acne) is the most common skin disease we see in dermatology practice. Clinically, it is characterized by a combination of open and closed comedones (formally referred to as noninflammatory lesions) and inflammatory papules and pustules. Comedonal acne is more typical in young adolescents, but can occur in combination with inflammatory papules and pustules at any time. Topical retinoids have long been advocated for the treatment of comedonal acne. AIMS: Given the increasing recognition of the inflammatory nature of acne and the synergistic benefits seen with fixed combinations we review the latest clinical data to provide guidance on optimal management of comedonal acne...

Acne and hidradenitis suppurativa (HS) both centre on hair follicles. They often occur together as part of the acne tetrad, but are found in distinct localizations. Acne is primarily defined by the presence of comedones and inflammatory lesions. However, in HS the intertriginous localization and chronicity play equally important roles for the diagnosis to the inflammatory lesions. Genetics, bacteria, environmental factors and innate inflammation have all been found to play a role in acne and/or HS. Surprisingly, there is little overlap between the findings so far...

BACKGROUND: Acne is an inflammatory disease of the pilosebaceous follicle, affecting 41-54% of adult women, with a particular form that involves the mandible. METHODS: We characterized infundibulum morphology in two groups of adult women using reflectance confocal microscopy. First, we investigated acne visually "healthy zones" on the forehead in 15 adult women with diffuse acne and compared with acne-free controls. We then compared healthy forehead and affected mandibular zone in 15 acne patients with mandibular involvement...

An 11-year-old boy presented with a 1-year history of multiple comedonal lesions distributed over his body. The lesions (Figure 1) were densely distributed throughout his body. Ophthalmologic examination revealed hyperpigmented conjunctival mucosae and enlarged meibomian glands (Figure 2). His nails were also hyperpigmented. In addition, he had been coughing and had a fever, each present for a month. Significant laboratory studies included mild anemia (hemoglobin 11.6 gm%) and leukocytosis of 20,800. A chest x-ray was suggestive of interstitial lung disease...

Acne is a multifactorial dermatosis, which is influenced not only by hormones but also by the biochemical relationship between them and the pilosebaceous unit. Inflammatory cytokines, chemokines, active oxygen, and zinc are known to be associated with the development of acne. Further, steroid metabolism is known as one of the important factors related to sebum secretion and comedone formation in acne. However, there is a lack of studies comparing these human biomarkers between healthy individuals and patients with acne...

Panfolliculoma is a benign neoplasm of follicular differentiation, and its morphological characteristics are similar to those of trichoblastoma, but it shows greater follicular differentiation. A 55-year-old female patient, visited for a dermatological consultation, presented comedo-like lesions on the eyelids, which were accompanied by moderate pruritus that spread gradually. On examination, the patient had localized dermatosis on the face, which symmetrically affected both upper eyelids and to a lesser extent the lower eyelids...

Acne vulgaris is one of the most common dermatologic condition especially among adolescents. Acne is related to excess sebum production by sebaceous glands, inflammation both within and adjacent to the comedones, hyperproliferation of Propionibacterium acnes. Some of investigations show association between acne and diet. Milk increases the level of IGF-1 leading to the synthesis of androgen-mediated increases sebum production. Chocolate predispose to hyperglycemia and insulinemia which aggravate of acne vulgaris...

BACKGROUND/OBJECTIVES: Acne, a common pediatric disease, tends to be more comedonal in preadolescents, whereas older individuals are more likely to have inflammatory lesions in addition to comedones. Thus the microbiome of preadolescents may be different. In this pilot study we aimed to characterize the preadolescent acne microbiome, compare the microbiome in preadolescents with and without acne, and investigate changes in the microbiome after topical treatment with benzoyl peroxide or a retinoid in a small cohort of preadolescents...

Winer's dilated pore is an infrequent appendageal tumor characterized by a giant comedone on the face, neck, and upper trunk in adults. We report a 57-year-old woman who developed multiple asymptomatic black papules on both labia majora. Histopathology showed grouped dilated follicles lined by keratinizing squamous epithelium in the superficial dermis. The superficial lining epithelium and interfollicular epidermis were atrophic, while the deep epithelium showed mild proliferation and melanin pigmentation with a few short projections extending into the surrounding dermis...

We present a case of postmenopausal-onset nevus comedonicus in a 58-year-old white woman with no relevant medical history. Two years before presentation, the patient had had a solitary red nodule, measuring 3.8 cm wide, on the mid lateral region of her left thigh. This progressed to a large area, 11.4 cm wide and 14 cm long, of multiple pruritic and painful red nodules, cysts, and deep open comedones extending across the lateral part of the left thigh, with less severe segmental extension to the lateral aspect of the left leg...

Introduction Chronic cutaneous lupus erythematosus (CCLE) usually presents as characteristic erythematous patches and infiltrated coin-shaped plaques. However, there are some atypical clinical variants that may mimic other dermatological conditions. Haroon et al. reported in 1972 an unusual presentation of CCLE with hypertrophic follicular scars seen in acne vulgaris. Acneiform presentation is one of the most rarely reported and one of the most confusing, as it resembles a very common inflammatory skin disease...

Acne is a chronic inflammatory skin disease that involves the pathogenesis of four major factors, such as androgen-induced increased sebum secretion, altered keratinization, colonization of Propionibacterium acnes, and inflammation. Several acne mono-treatment and combination treatment regimens are available and prescribed in the Indian market, ranging from retinoids, benzoyl peroxide (BPO), anti-infectives, and other miscellaneous agents. Although standard guidelines and recommendations overview the management of mild, moderate, and severe acne, relevance and positioning of each category of pharmacotherapy available in Indian market are still unexplained...

Acne is a chronic disease with a high prevalence among adolescents. Key pathogenetic factors (and their clinical correlates) are increased sebum production (seborrhea), follicular hyperkeratosis (comedones), and perifollicular inflammation (papules and pustules). The disease is modulated by a variety of endogenous (androgens, IGF-1, neuroendocrine factors) and exogenous (Propionibacterium acnes, diet, friction, ingredients of medical or cosmetic topical products) triggers. Acne is associated with high morbidity, and even mild manifestations may potentially cause considerable impairment in quality of life...
