Disease Profile

Fournier gangrene

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.

Fournier's gangrene


Fournier gangrene refers to the death of body tissue of the genitals and/or perineum. Signs and symptoms of the condition include genital pain, tenderness, redness, and swelling with a rapid progression to gangrene.[1][2][3] Although the condition can affect men and women of all ages, it is most commonly diagnosed in adult males. Most cases of Fournier gangrene are caused by an infection in the genital area or urinary tract. People with impaired immunity (i.e. due to diabetes or HIV) have an increased susceptibility to the condition. Treatment generally includes surgery and medications such as antibiotics and/or antifungal therapy.[1][2]
