Importance: Although the pathogenesis of hidradenitis suppurativa (HS) remains enigmatic, several factors point to potential involvement of the cutaneous microbiome. Insight into the cutaneous microbiome in HS using next-generation sequencing may provide novel data on the microbiological diversity of the skin. Objective: To investigate the follicular skin microbiome in patients with HS and in healthy controls. Design, Setting, and Participants: This case-control study obtained punch biopsy specimens from patients with HS (lesional and nonlesional) and healthy controls between October 1, 2014, and August 1, 2016...

The nail-patella syndrome involves a clinical tetrad of changes in the nails, knees, elbows and the presence of iliac horns. Nail changes are the most constant feature: absent, hypoplastic, or dystrophic. A pathognomonic finding is the presence of the triangular lunula. The diagnosis of nail-patella syndrome is based on clinical findings. In this paper we will discuss a case report of this syndrome and its relation with a dermatological finding.

A 70-year-old woman was referred to our dermatological unit by her general practitioner last summer, with a history of a two-month ulcerated purplish lesion on her left arm that spread centrifugally and that unsuccessfully treated with topical corticosteroids. The dermoscopic evaluation revealed an erythematous macula with central ulceration that showed the characteristic called "white starburst-like pattern" and some vascular structures (dotted vessels, polymorphous⁄ atypical vessels). The diagnosis of cutaneous leishmaniasis was made after histopathologic analysis and polymerase chain reaction essay...

Skin disease occur worldwide, affecting people of all nationalities and all skin types. These diseases may have a genetic component and may manifest differently in specific population groups; however, there has been little study on this aspect. If population-based differences exist, it is reasonable to assume that understanding these differences may optimize treatment. While there is a relative paucity of information about similarities and differences in skin diseases around the world, the knowledge-base is expanding...

Hidradenitis suppurativa (HS) is a complex dermatological disease characterized by recurrent painful nodules and suppuration in areas such as the axilla and groin. The disease is poorly understood and treatment is not satisfactory. In October 2016, the Canadian and United States Hidradenitis Suppurativa Foundations organized the inaugural Symposium on Hidradenitis Suppurativa Advances (SHSA) in Toronto, Canada. This meeting brought together experts from Canada, the United States, and Europe to discuss the latest advances in HS...

Hidradenitis suppurativa (HS) is a chronic skin disease that is difficult to manage and often refractory to medical management. Light and laser therapies have been utilized in the field of dermatology to treat a variety of skin conditions, but more recently were studied in the management of HS. Usually performed as outpatient procedures with a low risk of complications, they offer several advantages to traditional cold knife surgical procedures. We reviewed the various light- and laser-based treatments studied in HS and compared their efficacy...

Hidradenitis suppurativa (HS) is a chronic inflammatory disease that affects the follicular unit in apocrine glandbearing skin, resulting in deep-seated nodules, sinus tracts, abscesses, and ultimately scarring. HS is a highly distressing condition, and has one of the highest impacts on quality of life compared to other dermatologic diseases. Various topical therapies have been described that may be used alone or in conjunction with systemic or physical modalities for HS. Additionally, proper wound care is essential to the successful management of HS, particularly given the suppurative nature of the disease...

BACKGROUND: Staging and monitoring of patients with hidradenitis suppurativa (HS) have been traditionally based on clinical findings. However, the physical examination may show important limitations because of its poor sensitivity for differentiating between different lesion subtypes, and its low sensitivity to define the disease's activity. OBJECTIVE: To develop a consensus ultrasound (US) report that could summarize the relevant anatomical characteristics and staging of patients considering the experience of radiologists and dermatologists working on imaging of HS...

Patients undergoing Mohs micrographic surgery frequently experience anxiety as a result of multiple potential factors. There is currently no data regarding how this anxiety compares to other common procedures performed in dermatology offices, such as shave biopsy and excision, relative to a general dermatology visit. Herein, we conducted a survey of 471 dermatology patients at an academic medical center, using a validated tool (Visual Analogue Scale from 1 "no anxiety at all" to 10 "extremely anxious").

BACKGROUND: Dermatologic surgery is a well established subspecialty in dermatology, but observations suggest that the public may not be aware of this field. OBJECTIVE: To explore the public perception of the nature and scope of dermatologic surgery Methods: A cross-sectional online-based survey consisting of two parts was used. The first part recorded demographic data. The second part presented a series of clinical scenarios in common surgical and cosmetic procedures performed by dermatologic surgeons to determine respondents' choice among three specialties: general surgery, plastic surgery, and dermatologic surgery...

Despite characteristic features, psoriasis can mimic other dermatologic conditions, such as seborrheic dermatitis, lichen simplex chronicus, and certain nutritional deficiencies such as pellagra. We present a patient with a longstanding history of severe plaque psoriasis who presented with disfiguring scaly plaques involving greater than 80% body surface area. The patient's disease was minimally responsive to multiple therapies. Repeat punch biopsies demonstrated parakeratosis, psoriasiform hyperplasia, and dilated blood vessels consistent with psoriasis...

It is common for dermatology surgery patients to present on the day of surgery with more than one skin cancer needing Mohs micrographic surgery. When these carcinomas are located near one another, it may be more practical to treat both at the same time as the reconstruction for one defect may involve or otherwise affect the treatment or reconstruction for the other carcinoma. Treating both cancers on the same day creates an opportunity for efficient repairs where a creative single reconstruction may minimize the amount of tissue wasted during reconstruction,and minimize morbidity for the patient...

Superficial morphea, a rare variant of morphea, is characterized by hypopigmented to hyperpigmented skin lesions located predominantly in a symmetric fashion at intertriginous sites. These patches and plaques typically lack the significant induration, contractures, and atrophy seen in other subtypes of morphea. Histologic examination is key for accurate diagnosis considering the number of similar conditions which may clinically mimic superficial morphea. Herein, we present a case of a 25-year-old woman who re-presented for consultation in our clinic after gradual progression of her skin lesions...
