Erosive pustular dermatosis of the leg: report of three cases.
Erosive pustular dermatosis of the leg is a distinct form of spongiform amicrobial pustulosis. The disorder typically affects the lower limbs of elderly patients presenting with chronic venous insufficiency and stasis dermatitis, and has a chronic course. Three elderly patients with chronic venous ulcers are described, who developed pustules and moist eroded lesions on the leg. The clinical and histological features were typical for erosive pustular dermatosis. The lesions rapidly responded to topical treatment with either tacrolimus or corticosteroids. Of note, this condition was associated with a diverticular disease in two patients, while in another patient an epidermoid carcinoma of the tongue was present. Erosive pustular dermatosis of the leg is an uncommon but distinct skin disorder typically associated with trophic changes of the lower limbs. Our observations raise the question of the relation of erosive pustular dermatosis of the leg with the group of neutrophilic dermatoses. Topical immunotherapy with tacrolimus may constitute a novel therapeutic option for this frequently recalcitrant condition.
