Scientific news

Pityriasis versicolor and the other pityriasis conditions: understanding summer patches, avoiding confusion and preventing recurrence

Pityriasis versicolor is a superficial fungal infection caused by the proliferation of Malassezia yeasts, which are normally present on the skin. It produces fine light, brown or pink patches on the trunk, especially visible in summer. Topical antifungals are first-line; oral ones are reserved for extensive or recurrent forms. Pigmentation can take weeks to months to normalise, and recurrences are frequent because the yeast is commensal. The term 'pityriasis' also covers very different diseases (alba, rosea of Gibert, rubra pilaris, lichenoides).
