Phenotypic Heterogeneity in Bullous Congenital Ichthyosiform Erythroderma

Non-bullous congenital ichthyosiform erythroderma.

A 4-day-old neonate was brought with complaints of fissuring and peeling of skin involving almost the whole body. The neonate had generalized desquamation not even sparing the palms, soles and face. The parents informed that the baby was born, enclosed in a constricting parchmentlike membrane (collodion baby) that had gradually comeoff. There was a past history of a child born with similar pres...

Bullous ichthyosiform erythroderma

Bullous ichthyosiform erythroderma (BIE) is a rare disorder of keratinization (mutations in either keratin 1 or 10). It typically presents with fragile skin, which gives way to gradual evolutionof hyperkeratosis. Flaccid blisters, peeling, and superficial erosions at sites of minor trauma or friction are apparent within the first few hours of life. Yellow-brown, waxy, ridged or corrugated...

Phenotypic heterogeneity in bullous congenital ichthyosiform erythroderma: possible somatic mosaicism for keratin gene mutation in the mildly affected mother of the proband.

BACKGROUND Bullous congenital ichthyosiform erythroderma (BCIE) shows phenotypic variability. An epidermal nevus may represent somatic mosaicism for keratin gene mutation, which produces generalized BCIE in the next generation. This fact provides evidence that a postzygotic mutation can be passed on to the next generation in BCIE. We hypothesized that the same phenomenon occurred in a family wi...

Bullous congenital ichthyosiform erythroderma: safe and effective topical treatment with calcipotriol ointment in a child.

Sir, Bullous congenital ichthyosiform erythroderma (BCIE), or epidermolytic hyperkeratosis (MIM# 113.800), is a rare disorder of keratinization associated with blistering in its early phase. It was first described by Jean-Louis Brocq in 1902 as érythrodermie congénitale ichthyosiforme avec hyperépidermotrophie. Although most cases are sporadic, familial cases show an autosomal dominant pattern ...
