[Palmoplantar purpura in Duhring's herpetiform dermatitis].

Dermatitis herpetiformis Duhring (DHD) is characterized by polymorphism of its clinical picture. Haemorrhagic maculae on the palms and soles are rarely described. However, knowledge of this symptom is important because it may be the only clinical sign of DHD. We report two patients with DHD who presented with reddish-brown maculae on the flexure surface of their fingers and toes. The pertinent literature is reviewed.
