Plaque psoriasis: Plaque psoriasis is the most common form and produces dry, raised, red patches on the skin (lesions) covered with silver scales. Plaques may itch or be tender, and there may be few or many. They usually appear on the elbows, knees, lower back, and scalp.

Nail psoriasis: Nail Psoriasis can affect fingernails and toenails, causing pitting, abnormal growth, and color changes. Psoriatic nails can loosen and separate from the nail bed (onycholysis). Severe cases can cause nails to chip.

Droplet psoriasis: This type mainly affects children and young adults. Generally, it is triggered by a bacterial infection, such as strep throat. It is marked by small, drop-shaped, scaly lesions on the trunk, arms, or legs.

Inverse psoriasis. This mainly affects the skin folds of the groin, buttocks, and breasts. Inverse psoriasis causes soft patches of red skin that are made worse by friction and sweating. Fungal infections can trigger this type of psoriasis.

Pustular psoriasis. This rare form of psoriasis causes clearly defined, pus-filled lesions that occur in generalized patches (generalized pustular psoriasis) or smaller areas on the palms of the hands or soles of the feet.

Erythrodermic psoriasis. Erythrodermic psoriasis, the less common type, can encompass the entire body with a red, scaly rash, which can cause severe itching or burning.
