Pityriasis versicolor is a skin condition caused by Malassezia yeast, leading to pink to reddish hypo- or hyperpigmented, slightly scaly patches usually located at the sebaceous skin areas, i.e. upper trunk and arms. Subjective symptoms are rare, but include itch. In Scandinavia, the prevalence ranges from 0.5% to 4%. Risk factors include genetics, and immune suppression. The diagnosis is usually clinical, but may be supplemented by microscopy showing a “spaghetti meatballs” sign. Treatment involves topical or systemic antifungals. The prognosis is generally good, but recurrence may occur, as argued in this review.
