Flat Warts (Verrucae Planae) Confined to the Pigment of a Tattoo: A Rare Tattoo-associated Complication.

Tattoos are a form of decorative body art in which pigment dyes of different colors are inoculated into the skin. It is estimated that 15-25% of general population has one or more tattoos (1), and the reasons for the popularity of this procedure may include greater social acceptance, aesthetic appeal, or perhaps the option of using laser removal techniques to eliminate unwanted tattoos. Even though modern professional tattoos are usually performed in sterile conditions, complications still occur, and with increasing numbers of people getting tattoos, the incidence of tattoo-associated side-effects presenting to dermatologists, which may be as high as 2%, is likely to increase (2).

[Genitoanal infections caused by Panton-Valentine leukocidin (PVL)-positive Staphylococcus aureus : Smear infection or sexually transmitted disease?].

Panton-Valentine leukocidin (PVL) is a pore-forming exotoxin produced by certain Staphylococcus (S.) aureus strains, which is responsible for the increased virulence of the pathogen. Thus, infections caused by PVL-positive S.

Napthyridine-derived compounds as promising inhibitors for CrtM: a primer for the discovery of potential anti- agents.

The disease-free existence of humans is constantly under attack by a variety of infections caused by a variety of organisms including bacteria. Notable among the bacteria is which is an etiological organism for infections including impetigo, folliculitis, and furuncles. The response of the human immune system against this disease is often neutralized by the production of a pigment called Staphyloxanthin (STX) via a series of reactions mediated by several enzymes.

5-aminolevulinic acid-photodynamic therapy for a refractory severe kerion: A case report.

Kerion is a subtype of tinea capitis with a severe inflammatory response, requiring early diagnosis to prevent secondary bacterial infection, folliculitis and permanent alopecia. Oral antifungal drugs are considered the first-line treatment for tinea capitis; however, drugs therapy is challenged by the long treatment duration, side effects, and drug resistance. Photodynamic therapy (PDT) has been widely used to treat dermatomycosis and has shown significant efficacy in recent years.

Characterization and Risk Factors of Folliculitis after Hair Transplantation: A Multicenter Retrospective Study.

Background: Postoperative folliculitis is a common complication of hair transplantation (HT) requiring effective preventive interventions. This study characterized postoperative folliculitis and determined risk factors in patients undergoing HT.

Methods: The authors retrospectively reviewed 1317 patients who underwent HT and completed 9-month follow-up between January of 2018 and June of 2021 at 4 medical centers.

Normal Trichoscopic Findings after Hair Transplantation in Androgenetic Alopecia: A Prospective Case Series.

Background: Trichoscopy can be very useful for evaluation for hair transplantation (HT), helping rule out simulators of androgenetic alopecia (AGA). There are only a few reports about normal trichoscopic findings after HT.

Objective: The aim of this study was to evaluate donor and recipient area trichoscopy after FUE in HT without complications in AGA patients.

Diagnostic delay, comorbid hidradenitis suppurativa and the prognostic value of bacterial culture in folliculitis decalvans: A cohort study.

Background: Folliculitis decalvans (FD) is a type of primary neutrophilic cicatricial alopecia often leading to irreversible hair loss. Data on its epidemiology, clinical features, outcomes, and prognostic factors are limited.

Objective: To evaluate a cohort of patients with FD and identify characteristics of severe disease and prognostic factors which impede remission.

Gluteal Hidradenitis Suppurativa: Analysis of 83 Patients.

Background: In 2013, Canoui-Poitrine et al. identified three hidradenitis suppurativa (HS) phenotypes by a latent class (LC) analysis, based on anatomical sites of involvement.

Objective: To improve the classification of the gluteal phenotype (LC3) patients given their diverse lesion types and differences in clinical profile.

The clinicopathological spectrum of preclinical folliculitis keloidalis with correlation to its dermoscopic features: a cross-sectional analytical study.

Background: Folliculitis keloidalis (FK) is a chronic hair disorder commonly affecting males with afro-textured hair. It typically affects the nuchal area, but disease may also occur at extra-nuchal sites. Few studies have investigated the histopathological aspects of preclinical FK.
