A 25 year old bartender (or celery farmer or child playing in a wild parnsip field) presents with the rash shown above. He normally sleeps during the daytime and works at night and doesn't have the rash. Last weekend, however, he went out sailing and developed erythema, edema, and bullae on his hands a day later. They are painful but not pruritic. After the acute rash resolves, the patient has some hyperpigmentation of the skin lasting for months.
