In the second century AD, Claudius Galen, a Greek physician, surgeon and philosopher of the Roman Empire, utilized the term psoriasis for the first time, but his description was not consistent with the disorder that we now call psoriasis. He described psoriasis as a pruritic, scaly skin disease of the eyelids and scrotum. Although he used the term psoriasis, his description is now believed to most likely represent seborrheic dermatitis.
