Psoriasis is a common skin rash that affects almost 1 in 20 people in North America. Classically, psoriasis is seen on the skin as erythematous, well-demarcated plaques with silvery-white scale. However, there are other types of psoriasis as well: guttate, inverse, erythrodermic and pustular. Nail changes are also very common in all types of psoriasis and can help provide a clue to the diagnosis. Oftentimes, arthritis can coexist with psoriasis and cause major morbidity in psoriatic patients.
