[Delayed-type pressure urticaria].

Delayed pressure urticaria (DPU) is a rare disease of unclear pathophysiology and difficult to treat. Its typical manifestations are reddish, not itching swellings on parts of the body previously exposed to pressure and mostly only appearing 3 to 6 hours later. About 50% of the patients have general symptoms like fever, nausea and arthralgies. We report the case of a 36-year-old man who has suffered from DPU for 7 years. The incidence, symptoms and therapy of DPU are summarized and discussed in a short review of the existing literature.
