Examples of "parapsoriasis"
Pityriasis lichenoides chronica (also known as "Chronic guttate parapsoriasis," "Chronic pityriasis lichenoides," "Dermatitis psoriasiformis nodularis," "Parapsoriasis chronica," and "Parapsoriasis lichenoides chronica" "PLC") is an uncommon, idiopathic, acquired dermatosis, characterized by evolving groups of erythematous, scaly papules that may persist for months.
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 or larger in diameter. They can be very thin plaques that are symptomatic or mildly pruritic. Large-plaque parapsoriasis is a common associate of retiform parapsoriasis, can be accompanied by poikiloderma vasculare atrophicans, and can in rare occasions be a precursor to cutaneous T-cell lymphoma.
Pityriasis lichenoides et varioliformis acuta (also known as "acute guttate parapsoriasis", "acute parapsoriasis", "acute pityriasis lichenoides", "Mucha–Habermann disease", "parapsoriasis acuta", "parapsoriasis lichenoides et varioliformis acuta", and "parapsoriasis varioliformis") is a disease of the immune system. It is the more severe version of pityriasis lichenoides chronica. The disease is characterized by rashes and small lesions on the skin. The disease is more common in males and usually occurs in young adulthood, although it has been seen in every age group and every race. It is possible for the disease to go into remission for short periods of time or forever.
PVA fits within this updated view of parapsoriasis as a syndrome often associated with large plaque parapsoriasis and, or including its variant form, retiform parapsoriasis. Additionally, it may be considered a precursor or variant of the lymphomatous skin disorder mycosis fungoides, which is also associated with large plaque parapsoriasis. Large plaque parapsoriasis consists of inflamed, oddly discolored (such as yellow or blue), web-patterned and scaling plaques on the skin, or larger in diameter. When the condition of the skin encompassed by these plaques worsens and becomes atrophic, it is typically considered retiform parapsoriasis. PVA can occur in either the large plaque or retiform stage, but it can only be considered PVA when its three constituents (poikiloderma, telangiectasia, atrophy) are present. PVA is therefore considered an independent syndrome identified by its constituents, wherever it occurs.
Neoplasms can develop from parapsoriasis. For example, it can develop into cutaneous T-cell lymphoma.
PVA also has common names that include parapsoriasis-related terminology (i.e. parapsoriasis variagata, or "variegated" parapsoriasis). Parapsoriasis is a term first used by Brocq in 1902, intended to represent a group comprising a number of uncommon skin disorders, under a once used, now antiquated classification scheme for all inflammatory dermatoses (skin diseases known to be associated with or cause inflammation). Brocq chose the term "parapsoriasis" to illustrate that the dermatoses placed in this group had or would have commonalities with psoriasiasis, including appearance and chronicity (lifelong or indefinite duration). This poorly designated grouping has led to confusion in establishing a nosology (a method of classifying diseases and disorders) that associated or distinguished these disorders, and through the years differing opinions and uses regarding parapsoriasis by both authors and physicians has caused further confusion. In more recent times, after much discussion and growing consensus, parapsoriasis and its terminology has been revisited and re-examined often. Newer thought on parapsoriasis, such as by Sutton (1956) all the way to that by Sehgal, "et al." (2007) has cleared much of the confusion and has sparked increased understanding of parapsoriasis and its constituents.
PVA may be considered a rare variant of cutaneous T-cell lymphoma, a non-Hodgkin's form of lymphoma affecting the skin. It may also be included among a number of similar conditions that are considered as precursors to mycosis fungoides. PVA is believed to be a syndrome closely associated with large-plaque parapsoriasis and its cohort retiform parapsoriasis; including PVA, all three conditions fit within an updated view of the once ambiguous classification scheme known as parapsoriasis.
Retiform parapsoriasis is a cutaneous condition, considered to be a type of large-plaque parapsoriasis. It is characterized by widespread, ill-defined plaques on the skin, that have a net-like or zebra-striped pattern. Skin atrophy, a wasting away of the cutaneous tissue, usually occurs within the area of these plaques.
Parapsoriasis treatment consists primarily of light therapy (more specifically PUVA therapy or UVB therapy) possibly in combination with topical steroids.
The parapsoriasis groups, described and debated for nearly a century, has spawned a confusing nomenclature. There are some authors who prefer to limit the term "parapsoriasis" to large- and small-plaque variants only. However, the following classification scheme is now generally accepted:
Parapsoriasis refers to one of a group of skin disorders that are characterized primarily by their resemblance to psoriasis (red, scaly lesions), rather than by their underlying cause.
Small plaque parapsoriasis (also known as chronic superficial dermatitis) characteristically occurs with skin lesions that are round, oval, discrete patches or thin plaques, mainly on the trunk.
Poikiloderma vasculare atrophicans (PVA), sometimes referred to as parapsoriasis variegata or parapsoriasis lichenoides is a cutaneous condition (skin disease) characterized by hypo- or hyperpigmentation (diminished or heightened skin pigmentation, respectively), telangiectasia and skin atrophy. Other names for the condition include prereticulotic poikiloderma and atrophic parapsoriasis. The condition was first described by pioneer American pediatrician Abraham Jacobi in 1906. PVA causes areas of affected skin to appear speckled red and inflamed, yellowish and/or brown, gray or grayish-black, with scaling and a thinness that may be described as "cigarette paper". On the surface of the skin, these areas may range in size from small patches, to plaques (larger, raised areas), to neoplasms (spreading, tumor-like growths on the skin).
PUVA (psoralen and ultraviolet A) is an ultraviolet light therapy treatment for eczema, psoriasis, graft-versus-host disease, vitiligo, mycosis fungoides, large-plaque parapsoriasis and cutaneous T-cell lymphoma using the sensitizing effects of the drug psoralen. The psoralen is applied or taken orally to sensitize the skin, then the skin is exposed to UVA.
A French study by Binet et al., 1979, compared 0.1% Amcinonide ointment to equal strength Fluocinonide ointment, a similar corticosteroid already on the market. A double-blind comparative analysis was conducted to determine if Amcinonide was bioequivalent for the treatment of psoriasis and eczema. Each group contained both males and females of varying ages (mean = 54.8) and compared objective criteria (crust, scales, swelling, etc.) and subjective criteria (itching, burning, pain). It was found that treatment of dermatitis with Amcinonide achieved significant improvement over the one week trial period, thus demonstrating adequate efficacy in treating psoriasis, eczema, and even parapsoriasis.
Brocq provided early, comprehensive descriptions of numerous skin disorders, including keratosis pilaris, parapsoriasis and a form of dermatitis called "Duhring-Brocq disease" (named with Louis Adolphus Duhring and sometimes referred to as dermatitis herpetiformis). Other eponymous skin diseases named after him are "Brocq's pseudopelade", a condition involving progressive scarring of the scalp, and "Brocq-Pautrier angiolupoid", a specific type of sarcoidosis of the skin named in conjunction with Dr. Lucien-Marie Pautrier (1876–1959). With Pautrier he also described "Brocq-Pautrier syndrome" ("glossitis rhombica mediana"), characterized by rhomboid and shiny lesions on the midline of base of the tongue. Brocq is also credited for developing a tar solution used for the treatment of psoriasis.
PVA usually has an underlying cause, attributed to existing skin diseases and disorders associated with a cutaneous lymphoma or inflammation. Mycosis fungoides is the common lymphoma believed to cause PVA, although it may be considered a precursor when the lymphoma is occult (hidden) and undiagnosed. Large plaque parapsoriasis is another common causes of PVA. Less common causes include autoimmune-related connective tissue diseases such as lupus, dermatomyositis and scleroderma. Dermatoses and those that are genetically inspired, called genodermatoses, may also be an underlying cause of PVA. Among them, xeroderma pigmentosum and Rothmund-Thomson syndrome (poikiloderma congenita) are thought to be the most prominent. Ingestion of substances containing arsenic, such as arsphenamine, has also been suggested as a least common cause. PVA can also be idiopathic (of unknown cause), as seen in a small number of cases.
