Erythrodermic psoriasis: generalized involvement with loss of definition

Idiopathic erythroderma is sometimes called the ‘red man syndrome’. Generalised erythema and oedema affects 90 or more of the skin surface. Thick scaling may develop on scalp with varying degrees of hair loss including complete baldness. Psoriasis is a long-lasting autoimmune disease characterized by patches of abnormal skin. The development of generalized pustular psoriasis is often caused by an infection, abrupt withdrawal of topical corticosteroid treatment, pregnancy, hypocalcemia, medications, or following an irritating topical treatment for plaque psoriasis. Some of these genes are also involved in other autoimmune diseases. 15 52 The stratum granulosum layer of the epidermis is often missing or significantly decreased in psoriatic lesions; Erythroderma, or generalized exfoliative dermatitis, is a disease characterized by erythema and scaling of greater than 90 of the body’s surface. Some patients may experience involvement of their palms and soles, with hair loss and nail shedding. 16 Hyperkeratosis, parakeratosis, acanthosis and a chronic perivascular inflammatory infiltrate, with or without eosinophils, are examples.

Erythrodermic psoriasis: generalized involvement with loss of definition 2Psoriasis is a chronic skin disorder in which there are sharply defined red patches on the skin, covered by a silvery, flaky surface. Generalized Erythrodermic Psoriasis (also called psoriatic exfoliative erythroderma). The spine can be involved in many patients with PsA, even though stiffness and burning sensations in these areas are not the primary symptoms. It is generally believed to be caused by damage to factors in the immune system, enzymes, and other substances that control skin cell division. Plaque psoriasis accounts for 90 of all people with psoriasis. Sunlight: there is usually a decrease in severity during periods of increased sun exposure (ie it often improves in the summer and is worse in the winter) but a small minority has an aggravation of symptoms during strong sunlight and sunburn can also lead to an exacerbation of plaque psoriasis. Any systemic upset, such as fever and malaise, which are common in unstable forms of psoriasis such as erythroderma or generalised pustular psoriasis. Tools such as the Psoriasis Area and Severity Index (PASI) may be used to express disease severity, based on severity of lesions and extent of skin involvement. Generalized pustular psoriasis in pregnancy is also known as impetigo herpetiformis. Erythroderma is defined as a scaling pruritic, erythematous inflammatory skin eruption that involves over 90 of the body surface. Early recognition and intervention is important as PsA may lead to loss of function.

Generalized pustular psoriasis is also known as Von Zumbusch pustular psoriasis. Generalized pustular psoriasis is also known as Von Zumbusch pustular psoriasis. The nails may become deformed, and the disease can damage bone in the affected area. The severity of the disease may range from a minimal cosmetic problem to total body surface involvement. Moderate-to-severe psoriasis is typically defined as involvement of more than 5 to 10 percent of the body surface area (the entire palmar surface, including fingers, of one hand is approximately 1 percent of the body surface area 7 ) or involvement of the face, palm or sole, or disease that is otherwise disabling. Therapeutic approaches to generalized pustular psoriasis and psoriatic arthritis are discussed separately. Most patients will show a rapid decrease in inflammation with such therapy, but complete normalization of skin or lasting remission is unpredictable.


Erythroderma (Generalized Exfoliative Dermatitis). Author: Sanusi H Umar, MD, FAAD; Chief Editor: Dirk M Elston, MD more. Pustular psoriasis is an uncommon form of psoriasis consisting of widespread pustules on an erythematous background, as shown in the image below. Note the clearly defined, raised bumps on the skin that are filled with pus (pustules). The acute generalized type is also termed von Zumbusch variant. A minority of patients develop systemic involvement, most commonly hepatic, renal, and pulmonary systems. Szary syndrome is characterized by peripheral blood involvement of Szary cells. Erythroderma is defined as generalized erythema and scaling of at least 90 percent of the patient’s skin surface. Heat loss is a major concern secondary to the defective skin barrier. Change From Baseline in Body Surface Area (BSA) of Involvement of Lesion for Erythrodermic Psoriasis (EP) Over Time Time Frame: Baseline, Week 1, 2, 4, 6, 8, 16, 28, 36, 48 and 52 Designated as safety issue: No Calculation of BSA involvement in dermatological lesion is used to measure disease severity and treatment responses for participants with EP. Generalized pustular psoriasis is an unusual manifestation of psoriasis which may be gradual or acute in onset. Patients also experience weight loss, muscle weakness, hypocalcemia, leukocytosis, and increased ESR. Treatment success, as defined by the Division, is the proportion of subjects who achieve a score of 0 or 1 on the OLA at week 12. Generalized pustular psoriasis can also cause fever, chills, severe itching and diarrhea. Although the disease usually isn’t as crippling as other forms of arthritis, it can cause stiffness and progressive joint damage that in the most serious cases may lead to permanent deformity.

If control becomes difficult or if psoriasis is generalized, the patient may benefit from phototherapy, systemic therapy and referral to a physician who specializes in the treatment of psoriasis. Because localized plaque psoriasis is the most common form, the algorithm focuses on the treatment of this type of psoriasis. 4 Psoriasis is characterized by red, scaling plaques, ranging from only a few lesions to total involvement of the skin. Localized psoriasis can be defined as disease that is limited to such a degree that topical therapy controls it. Erythrodermic psoriasis is a particularly inflammatory form of psoriasis that often affects most of the body surface. It generally appears on people who have unstable plaque psoriasis, where lesions are not clearly defined. Erythrodermic psoriasis throws off the body chemistry, causing protein and fluid loss that can lead to severe illness. Pustular psoriasis also can be generalized, covering most of the body. Erythrodermic Psoriasis is also known as psoriatic erythroderma which is a generalized form of psoriasis or generalized redness of the skin that is affecting 90 of your body surface, including face, hands, feet, nails, trunks and extremities. It should be treated as a dermatological emergency due to the fact that a generalized redness signifies failure to the skin’s function that is manifested to many complications such as, dehydration, impaired thermoregulation and hypothermia, cardiac failure, anemia, protein loss and edema, death.
