Plaque psoriasis—the most common type—is often characterized by raised, inflamed lesions with a silvery white scale on the scalp, trunk, and extensor surfaces of the knees and elbows. It is also known as "psoriasis vulgaris." Read more about plaque psoriasis here.

Guttate (eruptive) psoriasis is characterized by small erythematous to salmon-colored drop-like lesions. Guttate psoriasis is the second most common type of psoriasis. Read more about guttate psoriasis here.

Pustular psoriasis is uncommon, with small pustules overlying erythemic skin on the trunk and extremities, including the nail beds. Read more about pustular psoriasis here.

Inverse psoriasis—present in body folds (ie, retroauricular, groin, abdomen, underarm, breast, and genital areas)—exhibits much less scaling than other psoriasis types. Read more about inverse psoriasis here.
