Prostaglandins, local hormones, are produced by almost every tissue and organ in the body (except for erythrocytes). They are active at the site of their production or next to the cells that secrete them. Prostaglandins play an important biological role, because they are involved in many physiological and pathological processes. Some of their effects are still unknown. They are involved in inflammatory process of the skin. They have been implicated as possible mediators of contact allergic dermatitis and among others, act in immune response. The use of prostaglandin in dermatology is still experimental. In the near future, they might be use in therapy for systemic scleroderma, aberration of extremity circulation with ulcers, vasculitis, etc. An overview is provided of prostaglandins in dermatology.
