Epidermolytic Ichthyosis

Epidermolytic Ichthyosis (EI) presents at birth with erythroderma, blisters or erosions, and larger areas of denuded skin. While skin fragility decreases with age, severe hyperkeratosis with a verrucous, ridged or cobblestone surface develops over time. Palms and soles may be severely involved or completely spared. There is a mosaic form of the disease, likely due […]

Epidermolytic Ichthyosis (EI) presents at birth with erythroderma, blisters or erosions, and larger areas of denuded skin. While skin fragility decreases with age, severe hyperkeratosis with a verrucous, ridged or cobblestone surface develops over time. Palms and soles may be severely involved or completely spared. There is a mosaic form of the disease, likely due to somatic mutation during embryonic development, in which the affected individual has features of the disease limited to certain areas of the skin, and often following the lines of Blaschko (so called ‘linear epidermolytic hyperkeratotic nevus’). A mild variant of EI with superficially peeling or denuded areas described as ‘molting’ or ‘Mauserung’ is known as superficial epidermolytic ichthyosis (SEI; previously termed ichthyosis bullosa of Siemens).
