Pernioses são o resultado de dano induzido por frio, principalmente, à microvasculatura de pele acral em indivíduos suscetíveis. Elas são mais comuns nos meses de inverno em climas frios e úmidos. Elas se manifestam como máculas, pápulas ou placas vermelho-púrpura que coçam ou doloridas, mais comumente afetando os dedos das mãos e dos pés, embora outras extremidades do corpo, incluindo calcanhares, nariz e orelhas possam estar envolvidas. Por causa do isolamento da temperatura corporal central, outras áreas, especialmente as laterais das coxas, podem estar envolvidas em áreas onde há uma camada espessa de gordura subcutânea. | |||

Chilblains are the result of cold-induced damage principally to the microvasculature of acral skin in susceptible individuals. They are commonest in the winter months in cold, damp climates. They present as itchy or painful red-purple macules, papules or plaques, most commonly affecting the fingers and toes, though other body extremities including the heels, nose and ears can be involved. Because of insulation from core body temperature, other areas, especially the lateral thighs, may be involved in areas where there is a thick layer of subcutaneous fat. | |||
