[Exanthem and painful leg in a 72-year-old female patient].

The case of a 72-year-old female patient with exanthem and concomitant neuropathy of the instep of the foot and progressive ipsilateral lower leg pain is reported. Sonographically, a superficial vein thrombosis with extension into the deep venous system originating from the exanthem was observed. On the basis of the clinical picture as well as the serological and electrophysiological findings, a rare diagnosis of acrodermatitis chronica atrophicans with peripheral neuropathy was made, which could significantly promote the local development of venous thrombosis.
