The genus Malassezia comprises lipophilic species, the natural habitat of which is the skin of humans and other warm-blooded animals. However, these species have been associated with a diversity of dermatological disorders and even systemic infections. Pityriasis versicolor is the only cutaneous disease etiologically connected to Malassezia yeasts. In the other dermatoses, such as Malassezia folliculitis, seborrheic dermatitis, atopic dermatitis, and psoriasis, these yeasts have been suggested to play pathogenic roles either as direct agents of infection or as trigger factors because there is no evidence that the organisms invade the skin. Malassezia yeasts have been classified into at least 14 species, of which eight have been isolated from human skin, including Malassezia furfur, Malassezia pachydermatis, Malassezia sympodialis, Malassezia slooffiae, Malassezia globosa, Malassezia obtusa, Malassezia restricta, Malassezia dermatis, Malassezia japonica, and Malassezia yamatoensis. Distributions of Malassezia species in the healthy body and in skin diseases have been investigated using culture-based and molecular techniques, and variable results have been reported from different geographical regions. This article reviews and discusses the latest available data on the pathogenicity of Malassezia spp., their distributions in dermatological conditions and in healthy skin, discrepancies in the two methods of identification, and the susceptibility of Malassezia spp. to antifungals.

“…Интересными наблюдениями, подтверждающими важную роль внешних и внутренних факторов в возникновении и утяжелении течения ВА, являются т. н. популяции, свободные от акне [47] Акне новорожденных встречаются приблизительно у 20% детей, возникают в первые 3-4 нед жизни ребенка, чаще у мальчиков [71]. Неонатальные акне важно отличать от акнеформных дерматозов и транзиторных состояний данной возрастной группы, в частности от неонатального цефалического пустулеза (neonatal cephalic pustulosis) и неонатального пустулярного меланоза (neonatal pustular melanosis), малассезия-фолликулитов [72,73]. В отличие от данных состояний, истинные акне характеризуются образованием комедонов, реже -появлением папул и пустул.…”

В статье представлены современные данные о патогенезе вульгарных акне (ВА), особенностях клинической картины, диагностике и терапевтической тактике у детей и подростков. Приведены сведения о влиянии наиболее значимых внешних и внутренних факторов на патогенез и риск развития ВА. На основе анализа Европейских методических рекомендаций и рекомендаций Глобального альянса по лечению и диагностике ВА сформированы соответствующие диагностические и терапевтические алгоритмы ведения пациентов. Также продемонстрирована важная роль назначения эффективной терапии в виде фиксированной синергичной комбинации активных веществ, представленных топическим ретиноидом (адапален) и бензоила пероксидом.

“…The number of lesions can vary from few to more than one hundred (Figure 2). 3,11,18,19 Although different species may be involved, all species have the same clinical presentation. Clinically, MF is difficult to distinguish from bacterial folliculitis and acne vulgaris.…”

“…Direct microscopical examination by 10%-20% KOH of pustules and follicular hairs can be used to confirm the diagnosis of MF, where an examination reveals abundant round spores budding yeast cells which supports the diagnosis (Figure 3). 5,19 Jacinto-Jamora et al graded the spore load per high-power field as shown in Table 1. Suzuki et al stated that MF was diagnosed when 10 or more yeast organisms per follicle (≥10 per visual field at 400 × magnification) were observed under direct microscopic examination.…”

Dermoscopic Examination in Malassezia folliculitis

Background: Malassezia folliculitis (MF) is the most common fungal folliculitis, and it is caused by yeast of the genus Malassezia. MF may be difficult to be distinguished clinically from acne and other types of folliculitis, causing misdiagnosis and improper treatment. Dermoscopy has been very useful to support the diagnosis of several types of folliculitis, including MF. Purpose: To know the role of dermoscopic examination in MF. Review: The diagnosis of MF can be identified by usual clinical presentation with direct microscopy and culture of the specimen, Wood's light examination, histopathological examination, and rapid efficacy of oral antifungal treatments. Several studies reported that dermoscopy provides a deeper level of the image that links the clinical morphology and the underlying histopathology. Some dermoscopic patterns are observed consistently with certain diseases, including MF, so these could be used for establishing their diagnosis. The dermoscopic features of MF seem to correlate with the current understanding of its etiopathogenesis. Conclusion: Dermoscopic examination in MF will reveal dermoscopic patterns including folliculocentric papule and pustules with surrounding erythema, dirty white perilesional scales, coiled/looped hairs with perifollicular erythema and scaling, hypopigmentation of involved hair follicles, and dotted vessels.
