Plaque psoriasis presents as dry, red, raised lesions covered in silvery white scales that may shed. A rare form of the disease, psoriasis annularis produces a distinct circular lesion. The irritation and nasty symptoms of psoriasis can be treated at Good Skin Care Clinic in Melbourne. As a rare form of the disease, this produces a distinct circular lesion. Psoriasis is most common in fair-skinned people and extremely rare in dark-skinned individuals. Plaque psoriasis (psoriasis vulgaris), the most common form of the disease, is characterized by small, red bumps that enlarge, become inflamed, and form scales. This disease is characterized by smooth, inflamed lesions and can be debilitating. Age, general health, lifestyle, and the severity and location of symptoms influence the type of treatment used to reduce inflammation and decrease the rate at which new skin cells are produced. Psoriasis annularis.
Meaning of psoriasis universalis medical term. Etretinate, for example, produces fetal abnormalities and should never be used by women of childbearing age. Psoriasis annularis. Psoriasis characterized by small distinct lesions that generally occur over the body. Some of the types include annular erythema (deep and superficial), erythema perstans, erythema gyratum perstans, erythema gyratum repens, darier erythema (deep gyrate erythema) and erythema figuratum perstans. – forms an expanding annular lesion with a distinct red border and partially clearing middle at the bite site (bulls-eye). ANNULARIS or PSORIASIFORM-like rash that develops most commonly on the face definition and epidemiology – young, black women lesions – different from DLE: the lesions are ACUTE and BENIGN. – generalized pustular (lifethreatening) (C) ERYTHRODERMIC: – very rare, occurs in those with unstable plaque psoriasis therefore lesions not clearly defined. – trunk: only in diffuse type 5) GVHD, scleroderma diabeticorum, porphyria, scleromyxedema, phenylketonuria – connective tissue diseases that produce Raynaud’s phenomenon: lupus and rheumatoid arthritis 6) generally difficult to treat.
A punch biopsy within the interior of the lesion is also additionally helpful, especially if the lesional skin seems deeply involved (indurated). There is an important differential diagnosis list of other things like hand dermatitis, including: atopic dermatitis involving the hand, tinea (superficial dermatophyte fungus infection), allergic contact dermatitis, psoriasis, lichen planus, scabies, herpes simplex, pityriasis rubra pilaris, and cutaneous lymphoma. Erythema elevatum diutinum (EED): a rare chronic form of fibrosing vasculitis. Linear psoriasis, an extremely rare form of generalized psoriasis, presents with asymptomatic, sharply demarcated plaques that are erythematous and scaly; the lesions are arranged in a linear distribution. Schamberg disease usually presents as asymptomatic and persistent purpuric lesions, discrete or confluent, on the lower legs of adult patients; the lesions are non-blanching and nonpalpable. 9 Lastly, lichen aureus, although rarely occurring in a segmental distribution, has a distinct golden colour, papular component, chronic course, and band-like dermal inflammatory infiltrate that makes its differentiation from ULC possible. The familial form tends to be more protracted and severe and presents in erosive, linear, or ulcerative patterns or with atypical features affecting young adults and children.
Acanthosis nigricans, a skin disorder that has been linked to insulin resistance and a propensity to develop type II diabetes, has an increased incidence among children with excess body weight, whose numbers are growing in epidemic proportions in the United States. Several etiologies are incriminated but the hyperandrogenism-insulin resistance-acanthosis nigricans syndrome is rare. 5kg/m2) girl with a history of polycystic ovarian syndrome and pre-diabetes who presented with psoriatic plaques in her scalp and, subsequently, in areas mostly confined to where she had characteristic lesions of acanthosis nigricans. Erythrodermic sarcoidosis is a cutaneous condition and very rare form of sarcoidosis. Like Paget’s disease, DCIS is a rare form of male breast malignancy. CHAPTER 5 Diagnosis of Skin Disease N.H. Cox1 & I.H. Coulson2 1 Department of Dermatology, Cumberland In rmary, Carlisle, UK 2 Dermatology Unit, Burnley Genera. 5.6 Shape of lesions, linear and annular lesions, 5.8 Pattern of lesions, 5. Even common and important diseases such as psoriasis have no strict and unique diagnostic criteria; indeed, some feel (and genetic studies are perhaps starting to support the thesis) that what has been accepted as psoriasis should actually be more tightly classi ed morphologically 1 in order to help understand phenotypic heterogeneity 2; it may be that this common dermatosis is several different diseases or is expressed according to different pathomechanisms. Psoriasis: A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. Erythema: Redness of the skin produced by congestion of the capillaries. The lesions may be discrete or coalesce to form plaques. Eruptions are both psoriatic and lichenoid in appearance, but the diseases are distinct from psoriasis, lichen planus, or other recognized dermatoses. When a patient complains of a lesion of the genitor-anal area, a venereologist thinks at once of the possibility of a venereal disease, and tries to confirm or exclude it. Hence a brief mention of the lesions will be made, leaving aside the venereal diseases and lesions resulting from then and their various manifestations. It begins as pin-head size spots of dark brown or red-brown colour and spreads slowly to form large patches. Psoriasis punctata, psoriasis guttata, annularis and gyrate often involve scrotum, penis, genito-crural folds.
