PITIRIASIS alba, rosada, versicolor | Manchas blancas en la cara

Pityriasis is a group of common dermatoses that, although they share the name, have distinct causes and characteristics. Pityriasis alba is usually seen in children and adolescents, manifesting as hypopigmented patches related to dry skin and sun exposure. Pityriasis rosea, on the other hand, is a self-limiting eruption of probably viral origin, recognized by its "herald patch" and Christmas tree-like distribution. Finally, pityriasis versicolor is a superficial infection caused by yeasts of the genus Malassezia, which causes hypo- or hyperpigmented patches on the trunk and extremities.
