Résumé : Plaque psoriasis is the most common and well-recognized disease type. It affects more than 80% of patients. Sebopsoriasis is a term used when lesions predominate on seborrhoeic areas. Guttate psoriasis is characterized by an acute generalized eruption of small, usually less than 1 cm in diameter, erythematous scaly papules, distributed as “droplets” over the body. It is common in children and young adults with a family history of psoriasis and typically follows streptococcal infection of the upper respiratory tract. Guttate psoriasis and chronic plaque psoriasis are genetically similar conditions with a strong association to the PSORS1 genetic locus. Pustular psoriasis is a group of inflammatory skin conditions characterized by infiltration of neutrophil granulocytes in the epidermis clinically manifested with sterile pustules. The three typical pustular forms are generalized pustular psoriasis, palmoplantar pustulosis, and acrodermatitis continua of Hallopeau. According to the European Rare and Severe Psoriasis Expert Network consensus each subtype of pustular psoriasis is subclassified on the basis of the presence/absence of associated features. Erythrodermic psoriasis is a severe form of psoriasis characterized by generalized inflammatory erythema and scaling involving at least 75% of the body surface area. Precipitating factors may include inappropriate use of potent topical and systemic corticosteroids. Other clinical variants of psoriasis are nail and inverse (flexural) psoriasis. In pediatric population, psoriasis presents the same clinical types. However, lesions may differ in distribution and morphology. In the future, a more clearly defined clinical classification of psoriasis is needed to provide more specific management of each psoriasis type.
