Psoriasis – Definition
Psoriasis is a chronic, inflammatory skin disease. Knees, elbows, scalp, trunk, and nails are the most commonly affected areas. There are several types of psoriasis:
- Plaque — inflamed patches of skin topped with silvery, white scales (most common type)
- Guttate — small dot-like lesions
- Pustular — weeping lesions and intense scaling
- Inverse — in body folds (armpits, groin, under breasts)
- Erythrodermic — intense sloughing and inflammation of the skin
