[Polyneuropathy in Duhring dermatitis herpetiformis].

Polyneuropathies in patients with dermatitis herpetiformis (Duhring's disease) can be due to dapsone therapy as well as due to an associated enteropathy. Dapsone causes an axonal, purely motor neuropathy, whereas the neuropathy due to an enteropathy is mainly sensory in type. The characteristics of both neuropathies are described considering the clinical and electrophysiological findings in a patient with enteropathic neuropathy and improvement during continuous dapsone therapy.
