Short answer · Medically reviewed summary · Last updated: 2026-05-08
Linear and whorled nevoid hypermelanosis (LWNH) is a rare pigmentary disorder most commonly referred to by its descriptive name or the synonym Linear and whorled nevoid hypermelanosis. While sometimes historically confused with other pigmentary mosaicisms, this term is the standard nomenclature used in modern clinical literature to describe the characteristic hyperpigmented macules arranged in streaks and whorls following the lines of Blaschko. What are the common synonyms for Linear and whorled nevoid hypermelanosis? In medical literature, Linear and whorled nevoid hypermelanosis is occasionally referred to by older or descriptive terms.

Linear and whorled nevoid hypermelanosis (LWNH) is a rare pigmentary disorder most commonly referred to by its descriptive name or the synonym Linear and whorled nevoid hypermelanosis. While sometimes historically confused with other pigmentary mosaicisms, this term is the standard nomenclature used in modern clinical literature to describe the characteristic hyperpigmented macules arranged in streaks and whorls following the lines of Blaschko.
What are the common synonyms for Linear and whorled nevoid hypermelanosis?
In medical literature, Linear and whorled nevoid hypermelanosis is occasionally referred to by older or descriptive terms. Because it is a form of pigmentary mosaicism, it may be referenced in older texts as "zosteriform hyperpigmentation." However, clinicians strongly prefer the term Linear and whorled nevoid hypermelanosis to distinguish it from incontinentia pigmenti or hypomelanosis of Ito. Using the precise name is essential for patients, as 6 people with Linear and whorled nevoid hypermelanosis in the DiseaseMaps community have found that using the standard name helps in coordinating care with dermatologists and geneticists.
How is the condition classified in medical systems?
Official medical databases utilize specific identifiers to ensure consistent tracking of Linear and whorled nevoid hypermelanosis. These classifications help standardize the diagnosis across global health systems:
- Orphanet: Recognized as ORPHA:90038.
- OMIM: Documented under the entry #600676.
- ICD-10/11: Generally categorized under codes for other specified disorders of skin pigmentation.
Why are there multiple names for this condition?
The naming of Linear and whorled nevoid hypermelanosis has evolved as our understanding of genetic mosaicism has improved. Historically, any skin condition following the lines of Blaschko was often grouped together. As researchers identified that Linear and whorled nevoid hypermelanosis is a distinct entity characterized specifically by hyperpigmentation (and typically lacking the extracutaneous involvement seen in other conditions), the terminology was refined to provide a more accurate clinical description.
Next steps
