Case for diagnosis. Chilblains.
Chilblains are an inflammatory skin condition that develops following exposure to the cold. They consist of pruritic and/or painful erythematous-to-violaceous acral lesions and are the result of an abnormal vascular response to exposure to the cold. This benign condition is common in southern Brazil, particularly in Rio Grande do Sul where climatic conditions, together with cultural and economic aspects, facilitate the development of these sores.
