Psoriasis and psoriatic arthritis are complex and heterogeneous clinical entities, whose presentations comprise multiple combinations of subtypes. There are doubts even if they are distinct entities or merely variants of the same disease. Since 1964, when the relationship between psoriasis and psoriatic arthritis was recognized, many studies have been conducted to better understand the common mechanism of both diseases. Range in number from a few to many at any given time. Inverse psoriasis – A variant of psoriasis that spares the typical extensor surfaces and affects intertriginous areas (ie, axillae, inguinal folds, inframammary creases) with minimal scale. The diagnosis of psoriasis is almost always made on the basis of clinical findings. The distinctive, acute clinical presentation of guttate psoriasis characterized by small, droplike, 1-10 mm in diameter, salmon-pink papules, usually with a fine scale. Note characteristic lesions consisting of multiple, discrete, droplike papules with a salmon-pink hue. This variant of psoriasis primarily occurs on the trunk and the proximal extremities, but it may have a generalized distribution. Although episodes may recur, especially those due to pharyngeal carriage of streptococci, isolated bouts have commonly been described.
More specifically, the clinical spectrum of psoriasis includes the plaque, guttate, small plaque, inverse, erythrodermic, and pustular variants. Traditionally, psoriasis has been rightly taught to be rare. Genome-wide linkage scans have identified multiple loci linked to each disease and revealed overlap with psoriasis and atopic dermatitis susceptibility loci on chromosomes 1q21, 3q21, 17q25 and 20p12. Upper: comparison of clinical features seen in psoriasis and atopic dermatitis. Mutations in loricrin underlie the Mendelian skin disorder of Vohwinkel’s syndrome (113), but mutations or variants in other genes of the EDC have not yet been recognized in common skin disease.
Several clinical phenotypes of psoriasis are recognised, with chronic plaque (psoriasis vulgaris) accounting for 90 of cases. Five types of psoriatic arthritis have been proposed: distal interphalangeal joint only; Synonyms: acute generalised pustular psoriasis of von Zumbusch, pustular psoriasis von Zumbusch variant. Acute erythema is seen with a rapid spread of multiple sterile pustules over the body, concentrated in the flexures, genital regions and fingertips. Add notes to any clinical page and create a reflective diary. Recognised triggers 2 3. Older patients with the von Zumbusch-type variant have a poorer prognosis. Several psoriasis susceptibility loci are known, a number of which a. Here, we examined the role of these FLG variants in psoriasis using case:control association studies comparing Irish and UK psoriasis cohorts (combined n 691) to ethnically matched populations (combined n 2117).

Classifications have been proposed based on disease onset or the clinical course of psoriasis. Broadly, it has been classified into non pustular and pustular psoriasis. It is important to recognize precisely the clinical subtype as it has implications on the choice of treatment modality and also reflects upon the disease activity. Palmoplantar pustulosis, guttate and erythrodermic variants accounted for less than 2 of cases each. So, the results of various studies suggest that psoriasis is definitely a pruriginous disorder adding to the morbidity of this dermatosis. Numerous family studies have provided compelling evidence of a genetic predisposition to psoriasis, although the inheritance pattern is still unclear. In contrast, there are two localized variants termed palmoplantar pustulosis and acrodermatitis continua suppurativa (Figure 1H, depicting onychodystrophy in the latter condition). Infections, particularly streptococcal infections of the upper respiratory tract, have long been recognized as triggers of psoriasis.24 In addition, exacerbation or even initial manifestation of psoriasis has been observed in patients infected with the human immunodeficiency virus (HIV). The generation of psoriasis-like skin lesions has been described in animal models, by a process based on T-cell dysregulation without prior epithelial abnormalities. Many studies have documented the significant psychological impact of severe psoriasis. It has long been recognized that mental health conditions, including depression, anxiety, and suicidality, have been associated with psoriasis 4,10. This case describes a patient with long-standing psoriasis who presented acutely with both suicidal ideations and the erythrodermic variant of psoriasis, highlighting the need for depression screening and management in patients with severe dermatologic conditions. No interventions have been proven to reduce the risk of cancer developing in an area of leukoplakia, 6 but people are generally advised to stop smoking and limit alcohol consumption to reduce their risk. There are two main clinical variants of oral leukoplakia, namely homogenous leukoplakia and non-homogenous (heterogenous) leukoplakia, which are described below. The size and number of leukoplakia lesions in an individual is also correlated with the level of smoking and how long the habit has lasted for.
