Large plaque parapsoriasis (also known as parapsoriasis en plaques) are skin lesions that may be included in the modern scheme of cutaneous conditions described as parapsoriasis. These lesions, called plaques, may be irregularly round-shaped to oval and are 10 cm (3.93700787 in) or larger in diameter The term parapsoriasis refers to a heterogeneous group of uncommon dermatoses occurring mainly in older adults and characterized by erythematous and scaly patches of variable size, chronic course, and resistance to treatment [ 1,2 ]. It is broadly divided in two main types: small plaque parapsoriasis (SPP) and large plaque parapsoriasis (LPP)
Depending on the size of the plaques, the benign small-plaque and the large-plaque parapsoriasis prone to transformation into lymphoma are distinguished. The surface of some lesions may appear atrophic, wrinkled, resembling crumpled tissue paper. There may be telangiectasia, de-and hypopigmentation, which gives the foci similarity to poikilodermia Large plaque parapsoriasis should be treated, because treatment may prevent progression to MF (cutaneous T-cell lymphoma [CTCL]). Therapy includes mid- to high-potency topical steroids (class 2-4. No significant differences were observed between the patients' parapsoriasis and contralateral healthy skin or between large- and small-plaque parapsoriasis. Notable interpersonal variation was demonstrated. These results suggest that parapsoriasis is not associated with significant alterations in the cutaneous bacterial microbiome , scaly patches, and a chronic course. The condition is roughly classified into two types: large plaque parapsoriasis and small plaque parapsoriasis. Large plaque parapsoriasis is considered a premalignant condition that can progress t
Large plaque parapsoriasis, also called parapsoriasis en plaques, causes larger (more than 2 inches) scaly plaques than does SPP. In LPP, the trunk, legs, and arms have large oval or irregular-shaped, yellow-orange to red plaques. Just like SPP, LPP has a higher incidence in men past their middle age Parapsoriasis en Plaque Brocq, Large-Plaque Type, Parapsoriasis en Plaque Brocq, Large Focal Type, Parapsoriasis en Grandes Plaques, Premalignant Form of Parapsoriasis en Plaque.

Parapsoriasis is a peculiar reaction pattern of the skin that appears to have a spectrum with small plaque parapsoriasis at one end and large plaque at the other. The spectrum between is. At the present time, two clinically different forms of plaque type parapsoriasis have been identified: large-plaque parapsoriasis and small-plaque parapsoriasis. The link between MF and large-plaque parapsoriasis has been clearly established. The link between small-plaque parapsoriasis and MF has been rejected by most authors but is upheld by.
The large-heart inflammatory parapsoriasis en plaques is to be regarded as initial cutaneous T-cell lymphoma. The small-spot parapsoriasis is generally classified as indiopathic, benign, chronic dermatitis (some authors doubt the absolute benignity of small-spot parapsoriasis - see on this under Parapsoriasis en plaques benign small-spot form. Plaque psoriasis is the most common type. About 80% to 90% of people with psoriasis have plaque psoriasis. Other, less common types of psoriasis include: Inverse psoriasis appears in skin folds. It may look like thin pink plaques without scale. Guttate psoriasis may appear after a sore throat caused by a streptococcal infection. It looks like. Background: Parapsoriasis en plaques (large-plaque type)isa premalignant condition capableof developing intocutaneous T-cell lymphoma (CTCL). However, it isnotknown whether the early stage of CTCL can be distinguished from parapsoriasis en plaques. Objective: Our purpose was to determine whether parapsoriasis en plaques candevelop into CTCL Large plaque and small plaque parapsoriasis Current terminology of parapsoriasis refers to 2 disease processes that are caused by T-cell-predominant infiltrates in the skin . Small plaque parapsoriasis is defined by lesions less than 5 centimeters in diameter, whereas large plaque parapsoriasis lesions are often greater than 6 centimeters in diameter.

Small plaque parapsoriasis is a skin condition of unknown etiology that is part of a group of chronic, idiopathic dermatoses known as the parapsoriasis group, so-named for the presence of scaly plaques that clinically resemble psoriasis. Along with small plaque parapsoriasis, this group includes large plaque parapsoriasis, lymphomatoid. The role of the skin microbiome in parapsoriasis remains uncertain, but it would be important to further define how the microbiome changes during disease progression and to undertake metabolomics studies. Thus, as a further study we propose to compare the skin microbiome of large-plaque parapsoriasis with that of manifest cutaneous T-cell lymphoma

Like psoriasis, parapsoriasis is also marked by pink, scaly patches on the skin ranging from 1 cm to 5 cm in diameter, however, the plaques in parapsoriasis are often asymptomatic. There are two types of parapsoriasis: small plaque parapsoriasis (SPP) and large plaque parapsoriasis (LPP), with LPP being considered a premalignant dermatosis. Large plaque parapsoriasis, a disease of the middle-aged, and with no racial and geographical predilection, can be regarded as the clinically benign end of the mycosis fungoides disease spectrum.

Plaque psoriasis is the most common form of psoriasis. Treatment will depend on the severity of the symptoms, which doctors may determine using grading scales. In this article, we provide pictures. Large plaque parapsoriasis consists of inflamed, oddly discolored (such as yellow or blue), web-patterned and scaling plaques on the skin, 10 cm (3.9 in) or larger in diameter. When the condition of the skin encompassed by these plaques worsens and becomes atrophic, it is typically considered retiform parapsoriasis
