Psoriasis is a chronic inflammatory dermatosis, which in addition to the skin, can also and rarely affect the mucous membranes, which may include the oral, genital and ocular mucosa and whose particular surface anatomy may influence the clinical presentation. In this article, we will present the different clinical aspects of psoriasis of the ocular, genital, and especially oral mucosa. Each compartment of the eye may be affected, but the eyelid and conjunctiva are the main sites of involvement, whereas uveitis in the context of psoriasis is a therapeutic emergency. The genitals are very often affected during reverse psoriasis, however, this location is rarely examined systematically. Oral involvement is underestimated, although its prevalence would be much higher if psoriatic patients underwent a thorough oral examination. Indeed, in oral psoriasis, the clinical aspects are divided into two major categories: specific clinical aspects whose lesions have a parallel evolution and a common histology with skin lesions, and nonspecific ones that include the majority of oral involvement in psoriasis such as fissured tongue and geographic tongue.
