nEDD Gene: MVD AD

Onset: Birth, infancy to adolescence

Pathway: Lipid synthesis and transport

Category Paper: nEDD Paper

Key Clinical Clues

Lesions with characteristic double-edge scales (cornoid lamella).

Additional Cutaneous Features

Lesions presenting at birth are linear, pink-to-red and scaly; disseminated lesions present in adolescence or later, primarily on sun-exposed areas and featuring round-to-oval flat lesions. Histopathology: Thickening of the stratum corneum with a parakeratotic column, cornoid lamella, at the margin of lesions.

Treatment

Topical cholesterol/lovastatin (Atzmony, 2020; Paller, 2011).
