Erythromelalgia and psoriasis

Abstract

Psoriasis is a common, chronic devastating skin disease. Erythromelalgia is a rare disease characterized by episodic attacks of burning pain and inflammatory vasodilation in the distal extremities, especially after increased temperature. We are reporting 66year-old Japanese man diagnosed as erythromelalgia secondary to psoriasis. Although intravenous lidocaine, ketamine and oral steroid did not control his lesions and pain, low-dose aspirin successfully improved his pain. In addition, psoriatic macules were also dramatically healed at the same time. Low-dose aspirin is an old drug for the treatment of psoriasis, but still usable.
