ABSTRACT
Pityriasis versicolor (PV), also known as tinea versicolor, is caused by Malassezia species.
Clinical features of pityriasis versicolor include either hyperpigmented or hypopigmented
finely scaly macules. The most frequently affected sites are the trunk, neck, and proximal
extremities. In cases of pathogenicity, Malassezia can directly harm the host via virulence
factors or toxins, or indirectly by triggering damaging host responses. The diagnosis typically
relies on recognising characteristic clinical features. Due to the wide variability in its clinical
presentation, recognising the differential diagnosis is critical. Topical therapies are the primary
treatment for PV, encompassing nonspecific antifungal agents like sulphur with salicylic acid,
selenium sulphide 2.5%, and zinc pyrithione. Additionally, specific topical antifungal
medications with either fungicidal or fungistatic properties may also be incorporated into the
topical treatment regimen, such as imidazoles, allylamines, and ciclopirox olamine. Patient
education and the promotion of good personal hygiene are pivotal to reduce the risk of
recurrence. In this paper, we discuss the pathophysiology, risk factors clinical features,
diagnosis, and management as well as prevention of Tinea versicolor.
