Erythematous scaly plaques differential diagnosis

Psoriasis is a clinical diagnosis that encompasses a wide spectrum of presentations often categorized by morphology. 4 Plaque psoriasis is the most common pattern, characterizing 90% of cases. 3, 4.. Signs include erythema, swelling, vesiculation and exudation, or erythematous scaling and lichenification, depending on severity. These appear about 1 week after first contact with allergen, if previously unsensitized, or within hours to 1-2 days if sensitized. This is a relatively uncommon cause of balanoposthitis The histological diagnosis of MF is based on nu-merous subtle changes that can be present to some degree in other inflammatory and neoplastic cuta-neous conditions. Although the histologic features of MF vary according to the clinical stage, there are significant diagnostic criteria including Pautri-er microabscesses, haloed lymphocytes, allaymen

In the differential diagnosis of psoriasis, Vulgaris should be thinking generally five dermatological diseases. 1.Nummular eczema, 2. MF, 3. Pityriasis rubra pilaris, 4. Duhring's disease (dermatitis herpetiformis), 5. Bowen'sdisease. In this review will be discussed clues of differential diagnosis of psoriasis Cutaneous T cell lymphoma. Slowly evolving slightly scaly annular and roundish patches, plaques and sometimes nodules. Various morphologies including erythroderma. Buttocks, breasts common initial sites. Dermatitis neglecta. Build-up of scale due to avoidance of washing Localised erythematous, scaly and hairless, scarred plaques; often multiple; May be isolated to scalp or involve other body sites; Check nose, cheeks, ear concha; Lichen planopilaris; Localised, sometimes erythematous bald plaques; Perifollicular scale; Lonely hairs; Discoid lupus erythematosus of scal

Other commonly affected areas include scalp, ears, glabella and brows, nasolabial folds, axillae, chest, back, and groin Diagnosis is based on clinical findings and supported by a recent history of potential exposure. The eruption can be differentiated from tinea by its lack of scale and distinctive migrating course. The cutaneous infestation is self- limiting in that humans are dead-end hosts Abstract: Background: Psoriasis is an inflammatory skin disease presenting with erythematous and desquamative plaques with sharply demarcated margins, usually localized on extensor surface areas.

Scaly lesions • Psoriasis: silvery, scaled, well-demarcated plaques on skin, usually over the extensor surfaces. It can be pustular and involve the nails (nail pitting). • Dermatitis and eczema: a pruritic, exudative, or lichenified eruption on the face, neck, upper trunk, wrists, and hands, and in the antecubital and popliteal fossae Syphilis is a 'great mimicker' and should not be overlooked as a differential diagnosis of erythematous scaly rashes, especially as its global prevalence and incidence remain high. The incidence in high-risk populations in Australia has recently been increasing Subacute lupus erythematosus — annular plaques (with or without scaling) on sun-exposed areas. Basis for recommendation The information on differential diagnoses is based on expert opinion in a dermatology textbook [ Sterling, 2016 ] and review articles [ Chuh et al, 2015 ; Eisman and Sinclair, 2015 ; Drago, 2016 ; Villalon-Gomez, 2018 ; BMJ Best Practice, 2019 ; Yüksel, 2019 ]

Psoriasis is a clinical diagnosis, and a skin biopsy is usually not necessary for classic presentations of the disease. The characteristic lesions are sharply demarcated, scaly, erythematous plaques. The plaques may be pruritic and/or painful. They can be ovoid, round, or irregular in morphology and are often symmetrically distributed Five of the 14 patients with scalp involvement were diagnosed as having scalp psoriasis or seborrheic dermatitis before progression of their disease or tissue examination revealed the diagnosis of dermatomyositis. In all patients, the scalp involvement was manifested as atrophic, erythematous, scaly plaques Tinea corporis is a superficial dermatophyte infection characterized by either inflammatory or noninflammatory lesions on the glabrous skin (ie, skin regions other than the scalp, groin, palms, and soles).

Pityriasis rubra pilaris (PRP) is a relatively uncommon skin disease characterized clinically by erythematous scaly plaques with islands of normal skin, follicular plugs, and palmoplantar hyperkeratosis [].Nevertheless, in atypical cases, PRP has to be differentiated from other erythemato-squamous dermatoses especially plaque psoriasis (PP), which may at times be a diagnostic challenge [] Diaper rash, or diaper dermatitis, is a general term describing any of a number of inflammatory skin conditions that can occur in the diaper area. These disorders can be conceptually divided into 3 categories: Rashes that are directly or indirectly caused by the wearing of diapers: This category includes dermatoses, such as irritant contact. Diagnosis is clinical, and treatment is with topical antifungal therapy. Atopic dermatitis/eczema: inflammatory skin disease that most frequently affects children but can also be present in adults. Eczema is a chronic condition that presents with dry, crusted, erythematous plaques that may be intensely pruritic A general physical examination was normal, and cutaneous examination revealed multiple, well-defined erythematous scaly plaques with collaret scaling on the trunk and extremities (Figure 1).
