“…1 Cases of TV have been reported in newborns as young as 3 weeks. 2 Risk factors associated with neonatal Malassezia colonization include decreased gestational age, low birthweight, increased duration of NICU stay, exposure to antibiotics and steroids, central venous catheters, incubator humidity and heat, genetic predisposition, and potentially increased amounts of sebum production. 1,3,4 Our patient experienced many of these individual risk factors during the course of his hospital stay.…”

“…5 In previously reported cases, TV responded well to topical antifungals although systemic antifungals may be useful for severe or recalcitrant cases. 2,4,5 Though topical antifungals are efficacious, there is no data on the safety of their use in premature infants, and oral fluconazole can be used alternatively. Although rare in infants, TV is important to consider in the differential diagnosis of a hypopigmented rash even when the presentation deviates from the classical description.…”

“…[47][48][49][50][51][52][53][54][55] Rarely, tinea versicolor has been reported in infants including neonates. [56][57][58][59][60] Tinea versicolor is slightly more common in men than in women presumably due to increased sebaceous activity in men. 8,47,54 A positive family history of tinea versicolor is present in approximately 17% of affected individuals.…”

“…Examination of the lesion with a Wood lamp (filtered ultraviolet light with a peak of 365 nm) may show gold-yellow, yellowish-green or coppery-orange fluorescence, although some lesions do not fluoresce. 17,56 The fluorescence may include areas surrounding clinically visible lesions, suggesting that the fungal infection is spreading. 17 Dermoscopy is a useful ancillary tool for the diagnosis of tinea versicolor.…”

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

Although Pityriasis Versicolor(PV) may be virtually recognized by their characteristic clinical appearance. It is very difficult to diagnose atypical pityriasis versicolor occurring in uncommon sites especially flexural areas and extremities. Uncommon variant type such as plaque type of PV is difficult to differentiate from morphologically similar clinical conditions. Recurrence correlates with the extent of the skin lesions. All these clinical difficulties is overwhelmed by the effective basic tool Wood’s lamp.This study was an observational descriptive study, totally comprised of 100 clinically diagnosed cases of PV attending Dermatology Outpatient Department over a period of 1 year (October 2019 to October 2020) at Rajah Muthaiah Medical College. Ethical clearance was sought from Institutional Ethical Committee. After obtaining written informed consent detailed history was taken in relation to age, sex, duration of illness, and recurrent infections. Clinical examination of lesion includes site, types of lesions, and scaling. All the PV patients were evaluated under Wood’s lamp examination.To study the fluorescence pattern in clinically suspected cases of Pityriasis Versicolor.Out of 100 cases categorized into new and recurrent of PV cases were studied. Patients presented with achromic lesions 76 (76%), chromic were 20 (20%), combined chromic and achromic skin lesions were 4 (4%). Wood’s lamp yellow fluorescence were observed in 66(86.8%) among 76 chromic PV cases, 18(90%) patients among achromic 20 cases and the all the four cases of combined variant of PV(4%). We observed yellow fluorescence under Wood’s lamp in 88 cases (88%) out of 100 cases.Wood’s lamp adds a diagnostic value to find out the extent of PV early, and provides a valuable therapeutic tool to choose the mode of antifungal therapy to avoid recurrence and hypopigmentation thereby ensure complete clearance of PV by follow up Wood’s lamp examination. It was also useful to differentiate the similar morphological conditions.
