HISTORY
Hippocrates and his school (460โ377 BCE) provided meticulous descriptions of many skin disorders. In their classification, dry scaly eruptions were grouped together under the heading โlopoiโ. This group probably included psoriasis and leprosy.
Between 129 and 99 BCE, the word โpsoraโ (meaning a desquamative condition) was first used by Galen to describe a skin disorder characterized by a scaliness of the eyelids, corners of the eyes, and scrotum.

The condition was pruritic and excoriations were present. Although called psoriasis, this affliction was probably a type of eczema.
It was not until the nineteenth century that psoriasis was recognized as an entity distinct from leprosy. Although Robert Willan (1809) was the first to give an accurate description of psoriasis, it would be another 30 years before Hebra (in 1841) definitively separated the clinical features of psoriasis from those of leprosy. In 1879, Heinrich Koebner described the development of psoriatic plaques at sites of skin injury. The World Health Organization (WHO) passed a resolution in 2014 recognizing psoriasis as a โchronic, noncommunicable, painful, disfiguring and disabling disease for which there is no cureโ.
