Covering the entire human body, the skin is considered to be one of the most important organs,\nsince it is the first line of protection against chemical and biological external agents. Although the\nskin protects tissues and organs against external aggression, it can still be unbalanced by various\nskin diseases, such as psoriasis. This non-contagious inflammatory dermatosis is characterized by\nthe occurrence of erythematous lesions of various sizes covered with whitish scales. This scaling\nof the skin is the result of a rapid renewal of the epidermis, occurring over five to seven days instead\nof 28 days. Psoriasis vulgaris, or plaque psoriasis, is the most common form of this disease\nand is therefore commonly referred to by the term ââ?¬Å?psoriasisââ?¬Â. This work is a review of the literature\non plaque psoriasis, aiming at a better comprehension of the pathology at the histological\nlevel, but also to understand the genetic and environmental factors associated with this inflammatory\ndermatosis.
