Psoriasis is a long-lasting autoimmune disease characterized by patches of abnormal skin. These skin patches are typically red, itchy, and scaly. Psoriatic arthritis is a form of chronic inflammatory arthritis that has a highly variable clinical presentation and frequently occurs in association with skin and nail psoriasis. Skin characteristics typical for psoriasis are scaly, erythematous plaques, papules, or patches of skin that may be painful and itch. A chronic dermatosis of unknown origin, with erythematous, papular, and scaling lesions appearing in persistent and often enlarging plaques. The group includes acute and chronic lichenoid pityriasis and large and small plaque parapsoriasis. A chronic skin disease characterized by dry red patches covered with scales; The formation or presence of a salivary calculus (concretion formed in any part of the body). The skin is often a window to systemic disease. 1) is a common chronic, superficial inflammatory disease of the scalp, face (especially the eyebrows and nasolabial folds), ears, and central chest, affecting 2 to 5 of the population. Clinically, the disease is characterized by thin erythematous plaques, often with a fine, greasy scale. Differential diagnosis includes psoriasis, atopic dermatitis, allergic or irritant contact dermatitis, and dermatophyte (tinea) infections.
Psoriasis is a chronic inflammatory skin condition that is often associated with systemic manifestations. Diagnosis is based on the typical erythematous, scaly skin lesions, often with additional manifestations in the nails and joints. Approximately 90 percent of affected patients have plaque psoriasis, characterized by well-defined round or oval plaques that differ in size and often coalesce6 (Figure 1). Psoriasis is a complex, chronic, multifactorial, inflammatory disease that involves hyperproliferation of the keratinocytes in the epidermis, with an increase in the epidermal cell turnover rate (see the image below). Worsening of a long-term erythematous scaly area. Dermatologic: Most commonly, scaling erythematous macules, papules, and plaques; area of skin involvement varies with the form of psoriasis. Subsequently, poorly adherent stratum corneum is formed leading to the flaking, scaly presentation of psoriasis lesions, the surface of which often resembles silver scales. Psoriasis is a chronic inflammatory skin disease characterized by the formation of scaly and erythematous plaques. A Th1-cell mediated process is believed to be involved in the pathogenesis of psoriasis.
Any inflammatory disease of the sebaceous, or oil, glands of the skin. A chronic, generalized skin disorder characterized by an eruption of serum-filled vesicles (blisters). Localized redness and swelling of the skin, together with the formation of vesicles (blisters) in more severe cases, caused by skin contact with irritating chemical substances. Erythema may arise from a great variety of causes and disease. Psoriasis. The skin is affected by a vast number of insults and diseases, including genetic and metabolic abnormalities as well as infections and yet there is a limited number of ways in which it can respond. Erythema is red skin due to increased blood supply and it will blanch on pressure. A plaque is a palpable flat lesion greater than 0.5 cm in diameter. A granuloma is a histological term referring to chronic inflammation in which there are several types of inflammatory cells including giant cells. Psoriasis (PsO) Is a Chronic Inflammatory Disease of the Skin Inflammation is a tightly regulated, naturally occurring part of the body’s protective response to injury or infection, intended to prevent damage to surrounding tissue. The most common form of psoriasis, plaque psoriasis, manifests as well-demarcated, raised, scaly, erythematous skin lesions. Psoriasis plaque formation is thought to be caused by dysregulated immune activity within the skin. Pertaining to, characterized by, causing, resulting from, or becoming affected by inflammation.
Psoriasis is a chronic, multifactorial, inflammatory disease, characterized by circumscribed, scaling, erythematous macules, papules and plaques. Psoriasis is a chronic disorder that is relatively common. Psoriasis is a chronic inflammatory skin disease characterized by alterations in cytokines produced by both Th1 and Th17 pathways. The predominant clinical presentation of psoriatic lesions is characterized by the formation of scaly, well-demarcated erythematous plaques due to hyperproliferation of keratinocytes 6, 7. Psoriasis is a common, relapsing inflammatory skin disease characterized by erythematous scaly plaques. Psoriasis is a common chronic inflammatory skin disease that involves dysregulated interplay between immune cells and keratinocytes. Langerin(neg) conventional dendritic cells produce IL-23 to drive psoriatic plaque formation in mice. A skin and mucous membrane disease characterized by an eruption of macules, papules, nodules, vesicles, and/or bullae with characteristic bull’s-eye lesions usually occurring on the dorsal aspect of the hands and forearms. A vascular reaction of the skin characterized by erythema and wheal formation due to localized increase of vascular permeability. A chronic inflammatory disease of the skin with unknown etiology. The lesions develop as erythematous scaly patches that progress to crusted, pruritic, erythematous plaques. The Papulosquamous Diseases or Scaly Skin Diseases written by Charles Camisa, MD, FAAD. Psoriasis is a common inflammatory scaling dermatosis with a bilateral symmetric distribution that may be associated with a seronegative spondyloarthropathy. Clinically, it is characterized by groups of tiny sterile pustules that develop on a background of bright red skin. It usually develops during the course of chronic plaque-type psoriasis in adults.
