A new kind of skin lesion in Behçet's disease: extragenital ulcerations.

Abstract

A new skin lesion was encountered in 29 of 970 Behcet's patients. The lesions resembled oral aphthae clinically, were recurrent and left a scar tissue like genital ulcers but were located extragenitally. Skin biopsies could be done in only 4 cases and they all showed vasculitis.
