This condition occurs much more often in females than in males. Incontinentia pigmenti is characterized by skin abnormalities that typically evolve throughout childhood and young adulthood. Many affected infants have a blistering rash at birth and in early infancy. Though this blistering heals spontaneously, it can recur during illnesses with high fever. This blistering stage is followed by the development of wart-like (verrucous) lesions that also heal spontaneously. The blisters and wart-like lesions primarily occur on the arms and legs.  In infancy and early childhood, the skin develops grey or brown patches (hyperpigmentation) that occur in a swirled pattern. These patches, which can occur anywhere on the body, fade with time. Adults with incontinentia pigmenti usually have lines of unusually light-colored skin (hypopigmentation) on their arms and legs. These markings follow the paths along which cells migrate as the skin develops before birth (called the lines of Blaschko). Individuals with incontinentia pigmenti are at risk of stroke and vision loss, especially within the first year of life. These risks are due to abnormalities in blood vessels in the brain and  in the light-sensitive tissue that lines the back of the eye (retina). Affected individuals at risk often have developmental delays, intellectual disabilities, seizures, or other neurological problems. In the absence of stroke or another brain abnormality, most people with incontinentia pigmenti have normal intelligence.  Other signs and symptoms of incontinentia pigmenti can include hair loss (alopecia) on the scalp and other parts of the body, dental abnormalities (such as small teeth or few teeth), and lined or pitted fingernails and toenails. The features of incontinentia pigmenti may be mild or gone by the time affected individuals reach adulthood.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"5,000","Age_at_Onset_Snippet_Text__c":"as a Newborn","SourceID__c":"ORPHA:464","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0010631","ORPHANET_ID__c":"ORPHA:464","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Incontinencia pigmentaria","Spanish_Description_Source__c":"ORPHA:464","Spanish_Description__c":"Es una displasia ectodérmica multisistémica, sindrómica y ligada al cromosoma X, que se presenta en mujeres en forma de una erupción ampollosa que sigue las líneas de Blaschko (LB) seguida de placas verrugosas que evolucionan con el tiempo a unas máculas hiperpigmentadas de disposición arremolinada.
