Psoriasis is a chronic, complex, multisystem, inflammatory skin disorder that is multifactorial and noncontagious. Overall, about 2%-3% of people are affected worldwide. Genetic predisposition combined with environmental, immunologic, and still unknown triggers ultimately increase epidermal cell turnover rate.

Treatment of psoriasis is individualized according to type, severity, location, and distribution and extent of coverage on the body. Treatments include phototherapy, topical treatments (corticosteroids, salicylic acid, vitamin D analogues, coal tar 0.5%-33%, retinoids, and calcineurin inhibitors), and oral or injectable systemic medications (retinoids, methotrexate, cyclosporine, and biologics [including Th17, interleukin-12/23 and interleukin-23 inhibitors, and tumor necrosis factor inhibitors]). Adjunct therapies include stress reduction, moisturizers, and oatmeal baths. Combinations of agents and adjunct treatments may be necessary in some patients.

Psoriasis is generally divided into five main types: plaque, inverse, guttate, erythrodermic, and pustular psoriasis. Knowledge of psoriasis types leads to early recognition, diagnosis, and management of the physical, psychological, and social impact that patients experience.
