[Werner syndrome with torpid trophic ulcera cruris].

Werner's syndrome is a rare, autosomal recessive inherited disorder with a distinctive clinical picture. The characteristic physiognomy, shortness of stature with thin extremities, and large trophic ulcers are the key signs for the diagnosis. Premature greying of the hair and baldness, juvenile cataracts, a tendency to diabetes mellitus, hypogonadism, calcifications of the blood vessels, osteoporosis, metastatic calcifications of the soft tissue and an elevated incidence of neoplasms are further important features. We describe two patients with this disorder.
