Synopsis

Psoriasis is a chronic inflammatory disease of the skin with a likely immunologic basis. Hyperproliferation of epidermal cells leads to thickened, often scaly skin. Lesions usually develop slowly but may have a sudden onset of growth. Psoriasis is commonly categorized as mild (covers less than 3% of the body), moderate (3%-10%), or severe (over 10%).

Genital psoriasis is rather common and usually is comparable to psoriasis found elsewhere on the body. It can be isolated to the genitalia but is frequently part of more generalized involvement. There are 2 types of psoriasis that involve the penis: inverse psoriasis is found on the scrotum and the inguinal folds, and penile psoriasis is found on the glans and under the foreskin. Some individuals have tenderness during sexual intercourse.
