Abstract
Several types of psoriasis have been classified based upon a combination of morphology, distribution, and pattern. Plaque psoriasis is the most common and well-recognized form of psoriasis, also known as psoriasis vulgaris. It affects more than 80 % of patients. Guttate psoriasis is common in children and young adults with a family history of psoriasis and follows streptococcal infection of the upper respiratory tract or acute stressful life events. Characteristic acute generalized small, usually less than 1 cm in diameter, erythematous scaly papules develop over the whole body surface. The pustular variants of psoriasis can be divided into generalized and localized forms. Erythrodermic psoriasis is an acute, severe form of psoriasis characterized by generalized inflamed erythema and widespread scaling which affects more than 90 % of the body surface area. Additionally, psoriasis commonly presents at specific locations such as the scalp, nails, and body folds.
