Scalp folliculitis is a common disorder in dermatology. Its clinical spectrum includes three main forms: "simple" folliculitis with an ad integrum evolution without sequellar alopecia, Quinquaud's folliculitis decalvans, and acne keloidalis nuchae. The pathophysiology of scalp folliculitis remains poorly understood. The assumptions would be infectious and/or inflammatory causes possibly involving Staphylococcus aureus and Propionibacterium acnes (now referred to as Cutibacterium acnes according to a new taxonomic classification)...

Primary scarring alopecia (PSA) is caused by irreversible damage to the hair epithelial stem cells that reside in hair follicles. There is limited published work regarding PSA amongst the Asian population. The aim of this study was to evaluate the clinical features and to characterize the subtypes of PSA in southern Taiwan. In this retrospective case series, we reviewed 89 patients with pathology-confirmed PSA. The data was collected from National Cheng Kung University Hospital between 1988 through 2016. The clinical and histological data were reviewed, and the patients were characterized into different subtypes of PSA based on the clinical features and histological findings...

Acne keloidalis nuchae, a type of folliculitis involving the back of the neck, is common in black men, although rare cases have been reported in patients of other ethnicities. We analyzed the clinicopathological features of acne keloidalis nuchae in 17 Asians. Patients' age at the time of presentation ranged from 20 to 69 years. Most patients experienced the disease over 2 years (range, 3 months-20 years); follow-up data were available for 11 (65%) patients (range, 2-95 months). Nine (53%) patients had comorbidities, but none had a history of other skin disease or a family history of acne keloidalis nuchae...

BACKGROUND: Staphylococcal infection of the canine epidermis and hair follicle is amongst the commonest reasons for antimicrobial prescribing in small animal veterinary practice. Topical therapy with fusidic acid (FA) is an attractive alternative to systemic therapy based on low minimum inhibitory concentrations (MICs, commonly <0.03 mg/l) documented in canine pathogenic staphylococci, including strains of MRSA and MRSP (methicillin-resistant Staphylococcus aureus and S. pseudintermedius)...

More men are beginning to take advantage of opportunities to improve the health and appearance of their skin; however, the effectiveness of men's skincare regimens has not been well studied. The authors investigated the efficacy and tolerance of a twice-daily, three-step men's skincare regimen in improving skin appearance and reducing shave-related issues. Twenty-nine men who used a wet-shaving method completed a specific, three-step, twice-daily facial regimen-a Shave Cleanser, a Post-Shave Treatment, and Day Protection-in place of their usual routine for 4 weeks...

Malassezia folliculitis (MalF) mimics acne vulgaris and bacterial folliculitis in clinical presentations. The role of Gram staining in rapid diagnosis of MalF has not been well studied. In our study, 32 patients were included to investigate the utility of Gram staining for MalF diagnosis. The final diagnoses of MalF were determined according to clinical presentation, pathological result and treatment response to antifungal agents. Our results show that the sensitivity and specificity of Gram staining are 84...

Follicular urate-like crystals were first described in Necrotizing Infundibular Crystalline Folliculitis (NICF), a rare cutaneous disorder with multiple waxy folliculocentric papules. Similar crystal accumulation may be seen within follicular infundibulae as an incidental finding. We describe a case showing identical crystals occurring within the horn-like crusts of a patient with erosive pustular dermatosis of the scalp (EPDS), a condition which due to its presentation can often be mistaken for nonmelanoma skin cancer...

We report on a 21-year-old woman with a 3-year history of crusts and erosions on her scalp that had appeared after starting treatment with adalimumab due to Crohn's disease. By clinicopathological correlation pityriasis amiantacea with underlying folliculitis decalvans was diagnosed. Topical and systemic antibiotic treatment showed rapid response. The occurrence of pityriasis amiantacea in folliculitis decalvans associated with tumor necrosis factor (TNF)-α inhibitor therapy is remarkable and highlights the ambivalent role of TNF-α in diseases with immunological dysfunctions in combination with infections...

Autoimmune progesterone dermatitis (APD) is a cyclical cutaneous reaction to progesterone, with symptoms that typically begin 3-10 days before the onset of menstrual flow and end 1-2 days into menses. The symptoms vary in severity from barely visible to anaphylaxis, but most often include an eczematous eruption, erythema multiforme, urticaria, folliculitis, and angioedema. This is a rare disorder with only a handful of documented cases. The pathogenesis of this condition remains unknown and significant variations in the presentation and severity of symptoms complicates its diagnosis...

REVIEW

Traction alopecia was first described in 1904 but is still a cause of scarring hair loss in young women worldwide. It is unique in being initially a reversible then an irreversible (scarring) form of alopecia. Linked to tightly-pulled hairstyles, it is seen across all races. The pattern of hair loss depends on the style creating it but most commonly affects the frontotemporal hairline. There are some new examination findings associated with traction alopecia, which are traction folliculitis, the fringe sign and hair casts (pseudonits) on dermatoscopy...

Anti-tumor necrosis factor α (TNF-α) biologic agents are used for treating refractory sarcoidosis. However, sarcoidosis-like epithelioid cell granulomas may develop during anti-TNF-α treatment. A 63-year-old man suffering from rheumatoid arthritis was treated with oral methotrexate and methylprednisolone for 4 years. He subsequently started biweekly subcutaneous injections of certolizumab pegol. Three months later, light red follicular papules developed on his chest and they spread over the trunk and bilateral upper arms...

The activation of NLRP3, NLRC4 and AIM2 inflammasomes is pivotal for innate immunity against some pathogenic fungi, but their role in the pathogenesis of Malassezia folliculitis (MF) remains unclear. The objective of the study was to determine the expression of 4 canonical inflammasomes (NLRP1, NLRP3, NLRC4 and AIM2) and their priming-associated molecules (TLR2, TLR4, Dectin-1, Dectin-2 and NFκB) in MF lesion. Expression of NLRP1, NLRP3, NLRC4, AIM2, caspase-1, IL-1β, TLR2, TLR4, Dectin-1, Dectin-2 and NFκB was detected by immunohistochemistry in skin lesion of 23 MF patients and normal skin of 12 healthy subjects...

Malassezia species are lipophilic and lipid-dependent yeasts belonging to the human and animal microbiota. Typically, they are isolated from regions rich in sebaceous glands. They have been associated with dermatological diseases such as seborrheic dermatitis, pityriasis versicolor, atopic dermatitis, and folliculitis. The genomes of Malassezia globosa, Malassezia sympodialis, and Malassezia pachydermatis lack the genes related to fatty acid synthesis. Here, the lipid-synthesis pathways of these species, as well as of Malassezia furfur, and of an atypical M...

Folliculitis decalvans (FD) is classified as a primary neutrophilic cicatricial alopecia, and is estimated to account for approximately 10% of all cases of primary cicatricial alopecia. The role of dysfunctional immune activity and the presence of bacteria, particularly Staphylococcus aureus, appear pivotal. We describe a 26-year-old man with a 4-year history of FD that was recalcitrant to numerous systemic and topical therapies, whose disease was virtually cleared during a follow-up of 25 months following a course of treatment with systemic photodynamic therapy (PDT) using ultraviolet light (100-140 J/cm(2) ) with porfimer sodium 1 mg/kg as monotherapy...
