Disease Profile
Lymphomatoid papulosis
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance
Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.
Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.
X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.
X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.
Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.
Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary
Lymphomatoid papulosis (LyP) is a non-contagious, chronic skin condition characterized by the eruption of recurring, self-healing bumps (lesions) on the skin.[1] The lesions typically begin small and then become larger, and they may bleed or ulcerate before becoming scaly and crusty.[1][2] They often develop a red-brown color.[1] Symptoms associated with lesions may include itching and/or pain, which may be debilitating.[1][2] The frequency of eruptions varies over time and from person to person. Lesions may be very persistent, or they may go away for long periods of time before coming back.[1] They may occur anywhere on the body, but they typically develop on the trunk, arms, and legs, and may develop on the hands, face, and genitalia.[2][3] They generally go away on their own over a period of weeks to months (usually between 3 and 8 weeks), with or without scarring.[2] LyP is not contagious.[1][2] The cause of LyP is not known, but there is no evidence that it is hereditary.[1] Stress is often reported to trigger eruptions of lesions.[1] The duration of the condition varies from person to person and may last months, years or decades.[2]
A diagnosis of LyP requires evaluating the symptoms and having a skin
Treatment for LyP may speed up the healing of existing lesions or prevent new lesions from forming, but it does not change the overall course or duration of the condition.[2] People with only a few lesions or with no major symptoms or cosmetic concerns may opt to forego treatment. If treatment is desired, topical
