Eczema What and Psoriasis? is
Guttate psoriasis is the second most common type. Far less common are pustular psoriasis, which is characterized by pus-filled bumps known as pustules, and erythrodermic psoriasis, a very serious form of the disease that affects about 3 percent of people with psoriasis.
Psoriasis typically responds to treatment. Most psoriasis therapies aim to stop skin cells from growing so quickly and to smooth out the skin. But the disease may never go away completely, and it tends to come back.
Another option is light therapy, or phototherapy, in which targeted light rays are delivered to the skin. Because psoriasis can look like other skin conditions that cause itchy, scaly rashes with inflammation, it is often confused with various disorders. These may include common skin conditions such as acne, eczema, or heat rash. Most of the time, psoriasis can be diagnosed with a physical examination. However, a skin biopsy may be needed to rule out other possibilities and arrive at a definitive diagnosis.
Do you know how to spot signs of psoriasis? Here are some things you can look out for. The images that follow are of real medical conditions and may, in some cases, be graphic. Plaque psoriasis is the most common form of the skin condition , affecting about 80 percent of people with psoriasis. Usually starting as small red bumps on the skin, plaque psoriasis pictured develops into red patches with a silvery, scaly coating — these raised patches are called plaques.
Plaques usually show up on elbows, knees, and the lower back, and they can last for months or even years without treatment. Guttate psoriasis pictured — the second most common type of psoriasis — is characterized by multiple small, round red spots on the skin, usually widespread across the trunk and limbs. Often resulting from a bacterial or viral infection in children, such as strep throat, these spots come on suddenly and sometimes require oral medication or injections. Mild cases, however, may clear up without treatment.
A psoriasis skin rash tends to itch, burn, and feel sore. Patches of psoriasis commonly occur on your knees, elbows, and on your scalp. It can occur on your scalp, where it may be called dandruff , or on your face and chest. While doctors don't know the exact cause of seborrhea, it occurs across the age spectrum, in babies as well as in adults, and is usually treated with creams and lotions.
Pityriasis rosea pictured causes a red skin rash that is scaly and can look like guttate psoriasis. This skin rash is common in children and young adults. Like psoriasis, this skin rash is not contagious. Doctors do not know the exact cause, but pityriasis rosea may be due to a viral or bacterial infection. You can take medication to relieve the itching, and the rash should go away after a few weeks to months. And unlike psoriasis, this skin rash rarely comes back.
Like psoriasis, eczema pictured is a very itchy skin condition. Scratching causes redness and inflammation of the skin, leading to a worsening of the eczema.
Scratching can also cause a secondary bacterial infection. The most common type of eczema is caused by a reaction to irritants like detergents, soaps, or household cleansers.
So if you have eczema, you should be careful to use mild soap and regularly moisturize your skin. Your doctor may prescribe a steroid cream or other medications if eczema is severe. Some forms of psoriasis appear as pus-filled blisters that may be confused with pimples. Pustular psoriasis forms white blisters that are filled with pus and surrounded by red skin. Far more common than psoriasis, acne pictured also causes a pus-filled pimple eruption.
However — unlike psoriasis — acne is caused by excess oil, blocked pores, and bacteria. Acne is common in teens and young adults and occurs on the face, neck, back, or chest. Pustular psoriasis is usually seen in adults and can occur anywhere on the body, but less likely on the face. Like guttate psoriasis, measles pictured also follow symptoms of an upper respiratory infection in children and cause a skin rash of small, red spots. However, the measles skin rash usually starts on the face and spreads down to cover the body and is accompanied by fever, cough, and a runny nose.
Measles is caused by a virus and is contagious, though the measles vaccination has made this a rare disease in the United States. Shingles pictured is another viral infection that shares some symptoms with psoriasis. Like psoriasis, shingles can make your skin burn and itch and produces a red, blistered skin rash. The prevalence of AD is increasing worldwide. Some of its features are shown in Table The etiology of AD is only partially defined, but there is a clear genetic predisposition.
A characteristic defect in AD that contributes to the pathophysiology is an impaired epidermal barrier. In many patients, a mutation in the gene encoding filaggrin, a structural protein in the stratum corneum, is responsible.
Patients with AD may display a variety of immunoregulatory abnormalities, including increased IgE synthesis; increased serum IgE levels; and impaired, delayed-type hypersensitivity reactions.
The clinical presentation often varies with age. The infantile pattern is characterized by weeping inflammatory patches and crusted plaques on the face, neck, and extensor surfaces. The childhood and adolescent pattern is typified by dermatitis of flexural skin, particularly in the antecubital and popliteal fossae Fig.
The distribution of lesions in adults may be similar to those seen in childhood; however, adults frequently have localized disease manifesting as lichen simplex chronicus or hand eczema see below. In patients with localized disease, AD may be suspected because of a typical personal or family history or the presence of cutaneous stigmata of AD such as perioral pallor, an extra fold of skin beneath the lower eyelid Dennie-Morgan folds , increased palmar skin markings, and an increased incidence of cutaneous infections, particularly with Staphylococcus aureus.
Regardless of other manifestations, pruritus is a prominent characteristic of AD in all age groups and is exacerbated by dry skin. Many of the cutaneous findings in affected patients, such as lichenification, are secondary to rubbing and scratching.
