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
Differntiating Signs/Symptoms Lesions with slight erythema, slight to moderate scaling, and often perifollicular or frank follicular involvement. 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. Objective: To describe the common di erential diagnosis of plaque psoriasis classiﬁed accordin
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 ]
. 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).  Three anamorphic (asexual or imperfect) genera cause dermatophytoses: Trichophyton, Microsporum, and Epidermophyton.Dermatophytes may infect humans (anthropophilic) or nonhuman mammals.

Overview. Lupus erythematosus can be divided into three main subtypes: discoid lupus erythematosus (DLE), subacute cutaneous lupus erythematosus (SCLE) and systemic lupus erythematosus (SLE), all of which are photosensitive.DLE classically presents with erythematous-to-violaceous scaly plaques on the face and scalp with prominent follicular plugging, which often results in scarring and atrophy Actinic keratosis (AK) lesions are skin-colored, yellowish, or erythematous, ill-defined, irregularly shaped, small, scaly macules or plaques localized in sun-exposed areas of the body.
