Background: Pityriasis versicolor (PV) is a superficial mycosis caused by malassezia yeast, which is a lipophilic fungus. Lesions may be of hypopigmented, hyperpigmented, or mixed varant. Low sensitivity and specificity of KOH examination poses a diagnostic challenge in difficult cases where dermoscopy can be a useful aid.
