Bullous congenital ichthyosiform erythroderma (BCIE), also known as epidermolytic hyperkeratosis (EHK), is characterized by erythema and skin blistering of the newborn. The erythema is replaced with thick scaling later. Neonates with BCIE have higher risk of developing severe infection, such as sepsis.

Ichthyosis hystrix, Curth-Macklin type (IHCM) Ichthyosis hystrix, Lambert type (IHL)
Description
Ichthyosis hystrix is a rare autosomal dominant skin disorder characterized by spiky, verrucous hyperkeratosis of palms and soles. Diagnosis is supported by specific ultrastructural abnormalities such as perinuclear tonofibril shells of keratin intermediate filaments in binucleated suprabasal keratinocytes. It has been postulated that mutations in KRT1 result in a phenotype with the presence of palmoplantar keratoderma, the Curth-Macklin type (IHCM), while mutations in KRT10 cause the Lambert type (IHL), in which palmoplantar keratoderma is absent.

Striate palmoplantar keratoderma (SPPK) is an autosomal dominant genodermatosis characterized by linear hyperkeratosis of volar aspects of the fingers and on the palm as well as by focal hyperkeratosis on the soles. SPPK is a heterogenous group of disorders caused by mutations in either desmoglein 1 (DSG1), desmoplakin (DSP), or keratin 1 (KRT1).

Epidermolytic palmoplantar keratoderma (EPPK) is an autosomal dominant dermatosis that presents within the first year of life. Patients have diffuse thickening of the skin on the palms and soles with yellow discoloration and erythematous margins. Mutations are identified in KRT9. Mild form of EPPK is linked to KRT1.

Annular epidermolytic ichthyosis (AEI), also known as cyclic ichthyosis with epidermolytic hyperkeratosis (CIEHK), is a rare phenotypic variant of bullous congenital ichthyosiform erythroderma. AEI is an autosomal dominant disorder characterized by intermittent development of polycyclic, erythematous, scaly plaques on the trunk and proximal extremities. Mutations in keratin 10 or 1 have been identified in AEI.
