“…In addition to worsening the state of immunocompromised newborns and young children, Malassezia sp., a worldwide resident flora on the skin surfaces of people and animals, may cause pyoderma gangrenosum (PG), Malassezia folliculitis (MF), and seborrheic dermatitis (SD). The genus Malassezia has 18 different species [5].…”

Tinea versicolor, or pityriasis versicolor, is a common, superficial fungal infection of the skin that usually causes minimal discomfort. Finely scaled, hyperpigmented or hypopigmented macules are clinical characteristics of pityriasis versicolor. The researchers at Benha University Hospital wanted to learn more about the sorts of PV patients that visit their outpatient clinics. Two hundred and twenty-six Pityariasis versicolor patients who visited the Dermatology and Andrology Outpatient Clinics at Benha University Hospital participated in this cross-sectional research. Important variations in clinical manifestation were observed. Lesions that were both hypopigmented and hyperpigmented were most common on the back and chest. We discovered that skin type III was substantially linked to recurrent PV, hyperpigmented lesions, and chest discomfort. Varicella recurrence, hypopigmented lesion prevalence, neck and nape discomfort, and hyperhidrosis were all substantially linked to skin type IV. Age, male gender, and skin type III, as well as shoulder and chest involvement, were strongly related with recurrence, while the face was significantly connected with original lesions. Moreover, no age or gender variations were seen in relation to skin type in patients with PV condition.

“…They are part of the human cutaneous flora, of which colonization begins at birth and increases with age. 2 The site of involvement in PV varies depending on the age of the individual, with the face and neck being more commonly affected sites in children. The color of lesions varies from almost white to reddish-brown or fawn.…”

“…Tinea versicolor is characterized by mildly scaly hypopigmented or hyperpigmented macules/patches, most commonly affecting areas of skin that are rich in sebum production such as the trunk (especially the upper part), neck, shoulders and upper arms (Figures 1-3A). 19,21,24,[67][68][69] Facial involvement is less common in adults. On the other hand, facial involvement is common in children and may be the only site involved (Figure 3B).…”

A search was conducted in July 2022 in PubMed Clinical Queries using the key terms "tinea versicolor" OR "pityriasis versicolor". The search strategy included all clinical trials (including open trials, non-randomized controlled trials and randomized controlled trials), observational studies and reviews (including narrative reviews and meta-analyses) published within the past 10 years. Only papers published in the English literature were included in this review. The information retrieved from the search was used in the compilation of this article. Review AetiopathogenesisTinea versicolor is caused by dimorphic lipophilic and lipid-dependent yeasts in the genus Malassezia (formerly known as Pityrosporum) species, notably Malassezia globosa (M. globose), M. furfur and M. sympodialis. [2][3][4][5][6][7][8][9][10][11][12] Other species that have been implicated include M. restricta, M. obtuse, M. slooffiae, M. pachydermatis and M. japonica. [13][14][15][16] These yeasts are normal commensals on the skin surface. 17,18 Skin colonization increases with age; 25% of children and almost 100% of adults are affected. 19 Tinea versicolor occurs when the saprophytic yeast or budding form of the organism converts to the pathogenic hyphal or mycelial form. The fungal infection is localized to the stratum corneum. Predisposing factors for the conversion include a hot and humid environment, hyperhidrosis, application of oily lotion or cream to the skin, wearing of masks, excessive lipid-containing sebaceous secretions, malnutrition, poor general health, use of oral contraceptives, pregnancy, diabetes mellitus, use of topical or systemic corticosteroids, Cushing disease, Helicobacter pylori infection, immunodeficiency and genetic predisposition. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] A recent study showed oxidative stress has no role in the pathogenesis of tinea versicolor. 29
