Disease Profile

Papular mucinosis

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.

Age of onset





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.


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.


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.

Papular mucinosis is a rare skin disorder characterized by deposits of mucin in the skin. The terms "papular mucinosis" and "lichen myxoedematosus" are generally used interchangeably to describe the occurrence of this condition as a localized and less severe form, while the term scleromyxoedema refers to a generalized, more severe form.[1][2] Signs and symptoms of the condition include the presence of small, firm, waxy papules on the skin that are confined to a few sites on the body.[1] Affected individuals are typically otherwise healthy.[2] The cause of the condition is unknown, but it is commonly associated with monoclonal gammopathy. It has also been reported in association with bone marrow cancers as well HIV infection, hepatitis C, exposure to toxic oil and contaminated L-tryptophan.[1] Localized papular mucinosis typically does not require therapy, but topical corticosteroids and oral isotretinoin may help to reduce hardening of the skin.[1]
