noun
psoriasis
suh-RY-uh-sis/səˈraɪəsɪs/
A chronic skin condition that causes scaly, inflamed patches.
Her psoriasis causes itchy, scaly patches on her elbows.
Etymology
Greek psōriasis described being itchy rather than this specific modern diagnosis. The name became attached to the chronic skin condition marked by red patches and dry flakes.
In context
psoriasis is a Th1 immune system reaction where the immune system comes to the surface of the skin, secretes inflammatory markers, and that causes the skin to overgrow, which then causes the skin to be red
