This disorder has a chronic course and is commonly resistant to treatment. There are two types of parapsoriasis; small plaque parapsoriasis (spp) and large.
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 bridged by pityriasis lichenoides, pityriasis lichenoides chronica, pityriasis lichenoides et varioliformis acuta, and lymphomatoid papulosis.

Small plaque parapsoriasis, large plaque parapsoriasis and pityriasis lichenoides have all been shown to be monoclonal t cell disorders. These t cells belong to the skin-associated lymphoid tissue (salt). [2] this abstract terminological confusion with benign dermatosis, such as parapsoriasis en plaques, makes it dif þ cult to diagnose mycosis.
* large plaque parapsoriasis should be treated because this may prevent progression to mf (ctcl). - therapy includes mid- to high-potency topical steroids (class 2-4), topical nitrogen mustard, and topical carmustine (bcnu). - phototherapy with either broad- or narrow-band uv-b or puva can be effective in inducing remission.
The term “parapsoriasis” covers a large group of idiopathic cutaneous diseases characterized by asymptomatic or mildly pruritic, erythematous, scaly patches, and a chronic course. The condition is roughly classified into two types: large plaque parapsoriasis and small plaque parapsoriasis.
Large-plaque parapsoriasis transforms into ctcl in about 10% of patients per decade. Symptoms and signs the plaques are usually asymptomatic; their typical appearance is thin, scaling, dull, pink patches and plaques with a slightly atrophic or wrinkled appearance.

This is known to be extremely difficult to diagnose, both clinically and via laboratory tests. 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.
Regarding the type of lesion, 45 (73%) had large plaques and 17 (27%) small plaques.
Large plaque parapsoriasis is a chronic inflammatory disorder, and the pathophysiology has been speculated to be long-term antigen stimulation. This disorder is associated with a dominant t-cell clone, one that may represent up to 50% of the t-cell infiltrate.
Large plaque parapsoriasis large plaque parapsoriasis should be treated, because treatment may prevent progression to mf (cutaneous t-cell lymphoma [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.
Large plaque parapsoriasis 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 (4 in) or larger in diameter. They can be very thin plaques that are asymptomatic or mildly pruritic.
Nov 19, 2015 these patches, sometimes called plaques, usually itch or feel sore. They most often occur on the elbows, legs, scalp, lower back, face, palms.
About 80% to 90% of people with psoriasis have plaque psoriasis. Other, less common types of psoriasis include: inverse psoriasis appears in skin folds. Guttate psoriasis may appear after a sore throat caused by a streptococcal infection.

The prognosis of large-plaque parapsoriasis is dependent upon the outcome of mycoses fungoides, in most cases; who gets large-plaque parapsoriasis? (age and sex distribution) large-plaque parapsoriasis is a rare skin condition that is typically seen in middle-aged to older adults in the age group of 30-60 years.
To as large plaque parapsoriasis, on the basis of size, preferential distribution of lesions, and the presence or absence of atrophy and/or poikiloderma. 2 the skin lesions of both small-plaque parapsoriasis and large-plaque parapsoriasis are flat patches rather than infiltrated plaques, consistent with the fact that.
Sep 4, 2019 large plaque parapsoriasis should be treated, because treatment may prevent progression to mf (cutaneous t-cell lymphoma [ctcl]).
There are two types of parapsoriasis; small plaque parapsoriasis (spp) and large plaque parapsoriasis (lpp). Out of the two types, lpp is considered a premalignant dermatosis with a risk of progressing to mycosis fungoides or cutaneous t-cell lymphoma, while spp is a chronic benign condition.

Background: parapsoriasis en plaques (large-plaque type) is a premalignant condition capable of developing into cutaneous t-cell lymphoma (ctcl). However, it is not known whether the early stage of ctcl can be distinguished from parapsoriasis en plaques.

There are 2 general forms: a small plaque type, which is usually benign, and a large plaque type, which is a precursor of cutaneous t-cell lymphoma (ctcl). Treatment of small plaque parapsoriasis is unnecessary but can include emollients, topical tar preparations or corticosteroids, and/or phototherapy.
Large plaque parapsoriasis (lpp) is an idiopathic, chronic scaly dermatosis classified within parapsoriasis group of diseases, occurring commonly in middle aged patients of all races and geographic regions. Lpp and its variants are closely related to the patch stage of mycosis fungoides.

Treatment will depend on the severity of the symptoms, which doctors may determine using grading scales.
There are separate observations of mixed parapsoriasis - teardrop and plaque, teardrop and lichenoid. Depending on the size of the plaques, the benign small-plaque and the large-plaque parapsoriasis prone to transformation into lymphoma are distinguished.
In the large-plaque form, plaques are greater than 2 inches (5 centimeters) in diameter. Sometimes the plaques of small-cell parapsoriasis develop on areas of skin served by specific nerves that come out from the spinal cord, especially on the sides of the back and abdomen.
There are two types of parapsoriasis: small plaque parapsoriasis (spp) and large plaque parapsoriasis (lpp), with lpp being considered a premalignant dermatosis (potentially cancerous). Diagnosis of parapsoriasis can be difficult, but usually requires a skin biopsy.
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.
In the united states, the term ‘parapsoriasis en plaque’ is usually used to refer to the entity that in the united kingdom is called chronic superficial dermatitis. 771 the term ‘parapsoriasis’ is also used for a condition with large plaques, which in 10–30% of cases progresses to a frank t-cell lymphoma of the skin.
The plaque form of psoriasis may look like parapsoriasis when you first notice it, but it eventually becomes thick patches of flaky skin, usually on your knees, elbows, scalp, and lower back.
Twelve patients with large plaque parapsoriasis (lpp) were investigated for the presence of predominant t‐cell clones, analyzing the t‐cell receptor (tcr) γ‐chain gene. The diagnostic and prognostic significance of tcr gene rearrangement status was assessed by a correlation with the long‐term clinical follow‐up.
