Collodion baby, sometimes referred to as ‘collodion fetus,’ is a common presentation of several congenital ichthyoses, most of which are inherited in an autosomal recessive manner, including lamellar ichthyosis (li), congenital ichthyosiform erythroderma (cie).
Commonly the li cases is caused by various genetic mutations including tgm1(commonest), nipal4, alox12b, aloxe3, abca12, cyp4f22, pnpla1 (omim 615024), (17) and cers3 (omim 615023).

Most cases (approximately 75%) of collodion baby will go on to develop a type of autosomal recessive congenital ichthyosis (either lamellar ichthyosis or congenital ichthyosiform erythrodema). Lamellar ichthyosis (li) is one of the autosomal recessive congenital ichthyoses and is more severe than congenital ichthyosiform erythroderma (cie). This membrane usually dries and peels off during the first few weeks of life, and then it becomes obvious that affected babies have scaly skin, and eyelids and lips that are turned outward. Infants with this condition are typically born with a tight, clear sheath covering their skin called a collodion membrane.

Infants affected by lamellar ichthyosis are generally born with a shiny, waxy layer of skin (called a collodian membrane) that is typically shed within the first two weeks of life. Lamellar ichthyosis a congenital, chronic form of ichthyosis present at birth, inherited as an autosomal recessive trait, in which the affected infant is born encased in a collodionlike membrane (see collodion baby) that is soon shed, the skin then becoming covered with large, coarse scales with involvement of all of the flexures as well as the palms and soles. Any of a group of chiefly genetic disorders that are characterized by dry, scaly, and often thickened skin.
Plus, they become more susceptible to infections of the skin.
This susceptibility occurs because of the slow shedding process of the collodion, which the baby is left with scaly skin that can create a deep space between them.

It is one of three genetic skin disorders called autosomal recessive congenital ichthyoses (arci).
Lamellar ichthyosis (li) is a rare genetic skin disorder that is present at birth.
The skin beneath the collodian membrane is red and scaly. Lamellar ichthyosis (il) is a condition in which infants are born covered in a clear sheath called a collodion membrane.
