A 37-year-old male presented to our clinic with discolored patches on the neck, chest, and abdomen that had persisted for more than eight months. His medical history was unremarkable. Physical examination revealed numerous small, well-demarcated, round-to-oval patches with pigmentary changes and fine scaling in the affected areas (Fig. 1). The lesions were associated with pruritus. Routine laboratory tests were within normal limits. Direct mycological examination using potassium hydroxide (KOH) preparation revealed clusters of round spores and short, thick hyphal filaments, consistent with Malassezia globosa. These findings confirmed the diagnosis of pityriasis versicolor. The patient was treated with a combination of topical and systemic antifungal therapy, along with general hygiene measures. He was also advised to avoid prolonged moisture exposure in the affected areas and to wear clean, breathable cotton clothing.
Patient written informed consent was obtained.
