Psoriasis is an autoimmune disease that causes raised, red, scaly patches to appear on the skin. Plaque psoriasis is the most common form of the disease and appears as raised, red patches covered with a silvery white buildup of dead skin cells. Guttate GUH-tate psoriasis is a form of psoriasis that appears as small, dot-like lesions. It can cause severe itching and pain, and make the skin come off in sheets. However, approximately 30 percent of people with psoriasis will eventually develop psoriatic arthritis.

Plaque psoriasis (psoriasis vulgaris), the most common form of the disease, is characterized by small, red bumps that enlarge, become inflamed, and form scales. Removing these scales exposes tender skin, which bleeds and causes the plaques (inflamed patches) to grow. The lesions are well-defined, dry, nonpruritic papules or plaques overlaid with shiny silver scales, and they heal without scarring. Diseases that promote scale include fungal infections, psoriasis, and seborrheic dermatitis. Psoriasis is a chronic (long-lasting), non-contagious disease characterized by open sores in the skin that become covered with silvery-white scabs.
Psoriasis is a long-lasting autoimmune disease characterized by patches of abnormal skin. These skin patches are typically red, itchy, and scaly. They may vary in severity from small and localized to complete body coverage. Plaque psoriasis typically appears as raised areas of inflamed skin covered with silvery-white scaly skin. These areas are called plaques and are most commonly found on the elbows, knees, scalp, and back. They may develop anywhere in the body, except the soles of the feet and palms of the hands. Inverse psoriasis is characterized by inflamed, bright red, smooth patches of skin. Erythrodermic psoriasis the most uncommon form of psoriasis. As the disease progresses, eventually separate patches may join together to form larger areas. This is known as geographic plaques because the skin lesions resemble maps. This is a rare and severe form of psoriasis, in which the skin surface becomes scaly and red.
But in psoriasis, it lasts only a few days. The cells can’t shed fast enough, so they start to build up on the surface of the skin. Eventually, they form gray, white, or silvery lesions–creating the scaly-looking skin characteristic of psoriasis. Symptoms include, itching in groin, thigh skin folds, or anus, with red, raised, scaly patches that may blister and ooze. The patches often have sharply-defined edges and are often redder around the outside with normal skin tone in the center or abnormally dark or light skin. It is unusual for lesions to form on the face, but they may appear on the cheeks or at the hairline. Skin rapidly accumulates at these sites which gives it a silvery-white appearance. Commonly known as shingles, Herpes Zoster is a viral disease characterized by a painful skin rash with blisters in a limited area on one side of the body, often in a stripe. They look like fish scales under a microscope and present as a crusted or scaly patch of skin with an inflamed, red base. Every year, more than 9,000 people die from melanoma making melanoma the deadliest form of skin cancer. They are characterized by rough dry lesions or patches that appear on sun-exposed areas of the skin, such as the face, back of hands, arms, scalp or shoulders. The lesions may be red, pink, gray or skin colored. Psoriasis is a skin condition that creates red patches of skin with white, flaky scales.
Actinic Keratoses (AK’s) are common skin lesions caused by years of sun exposure and are considered the earliest stage in the development of skin cancer. An atypical or dysplastic nevus (mole) is a benign growth that may share some of the features of a melanoma, but is NOT a melanoma or any other form of cancer. The type of disease depends upon what level of the skin the blisters form and where they are located on the body. Granuloma annulare is a raised skin lesion that may be pearly white, skin-colored, red, or purple. Dry, itchy, flaky patches occur on the scalp, especially around the hair margins in the front and on the sides and in the back. The true cause of this scalp disease is not known, but stressful events and situations definitely aggravate it and make it get worse. With repeated rubbing and scratching, the skin can become thickened and darkened so that another condition called lichen simplex chronicus is present. Psoriasis belongs to a group of scalp diseases that are characterized by thick silvery scaly areas developing on various parts of the body. Mucha-Habermann disease, also known as pityriasis lichenoides et varioliformis acuta or PLEVA, is a rare skin disorder. Eventually, FUMHD may transform into the less severe form of Mucha-Habermann disease. Pityriasis rosea is a self-limited, mild, inflammatory skin disorder characterized by scaly lesions that follow a pattern on the skin. Create a free account to save it. Pneumonia is the most common complication of influenza; bacterial pneumonia is the most common form. Pityriasis rosea is a relatively mild skin disorder characterized by a salmon or pink colored, scaly rash. Researchers believe that pityriasis rosea is caused by an infectious pathogen, but they have been unable to isolate and identify such a pathogen. (For more information on this disorder, choose psoriasis as your search term in the Rare Disease Database.). They group together to form a flat red patch, which becomes brown and then slowly fades away over weeks to months. Cat Scratch Disease. CSD is a benign self-limited zoonotic infection, characterized by a primary skin or eye lesion, following cat scratches or contact with a cat and subsequent tender lymph nodes. It presents with an itchy, scaly rash, although there may be small blisters if the reaction is acute. Psoriasis is a disorder of the skin, which typically consists of red plaques covered by silvery-white scales.
11 Ways To Beat Psoriasis
Nonmalignant lesions account for most dermatologic disorders seen by urologists. Although rare in the United States and minimally emphasized in medical schools, some infectious diseases are showing resurgence because of increased world emigration and the spread of resistant forms of disease. Patch: This is a larger (1 cm) area of color change that is nonpalpable (ie, level with the skin). Like papules, they can be any color or texture. Often, this represents a confluence of papules. A distinct characteristic is that the vesicle collapses when it is incised and the fluid is removed. The only way to know if your skin is healthy and intact is to look at it regularly. Take part in activities that distract from the itching during the day and make you tired enough to sleep at night. Psoriasis is a chronic disorder of the skin characterized by reddish, scaly patches of inflammation, most commonly affecting the elbows, knees, scalp, and/or groin. Lesions are most commonly found on the tongue and the buccal mucosa; they are characterized by white or gray streaks forming a linear or reticular pattern on a violaceous background (see the image below).
