[Generalized diabetic dermangiopathy].

Report on a 37-years old male with infantile diabetic manifestations. He is suffering now from severe diabetic retinopathy, nephropathy, neuropathy and a fresh myocardiac infarction. The entire integument is spotted with single brownish-red patches, each one from 3 to 10 mm in diameter. The patches are partly topped by a slight scale. After healing an atrophic macule is left. They meet the pretibial "Atrophic circumscribed skin lesions" described formerly by Melin. The exanthema was therefore classified as a generalized diabetic dermangiopathy. It is suggested to subdivide the diabetic dermangiopathies in a pretibial type Melin and a generalized type Bauer-Levan. Histologically a severe vasculitis can be found with all types.
