Congenital reticular ichthyosiform erythroderma(IWC)

MedGen UID:
777141
Concept ID:
C3665704
Disease or Syndrome
Synonyms: ICHTHYOSIS WITH CONFETTI; IWC
SNOMED CT: Congenital reticular ichthyosiform erythroderma (703504006); Ichthyosis with confetti (703504006); Ichthyosis variegata (703504006); CRIE - Congenital reticular ichthyosiform erythroderma (703504006)
Modes of inheritance:
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

Ichthyosis with confetti (IWC), also known as congenital reticular ichthyosiform erythroderma (CRIE), is a rare skin condition characterized by slowly enlarging islands of normal skin surrounded by erythematous ichthyotic patches in a reticulated pattern. The condition starts in infancy as a lamellar ichthyosis, with small islands of normal skin resembling confetti appearing in late childhood and at puberty. Histopathologic findings include band-like parakeratosis, psoriasiform acanthosis, and vacuolization of keratinocytes with binucleated cells in the upper epidermis, sometimes associated with amyloid deposition in the dermis. Ultrastructural abnormalities include perinuclear shells formed from a network of fine filaments in the upper epidermis (summary by Krunic et al., 2003). [from OMIM]

Clinical features

From HPO
Palmoplantar keratosis
MedGen UID:
44017
Concept ID:
C0022596
Disease or Syndrome
Abnormal thickening of the skin localized to the palm of the hand and the sole of the foot.
Clubbing
MedGen UID:
57692
Concept ID:
C0149651
Anatomical Abnormality
Broadening of the soft tissues (non-edematous swelling of soft tissues) of the digital tips in all dimensions associated with an increased longitudinal and lateral curvature of the nails.
Short stature
MedGen UID:
87607
Concept ID:
C0349588
Finding
A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to "short stature" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).
Decreased body weight
MedGen UID:
1806755
Concept ID:
C5574742
Finding
Abnormally low body weight.
Erythroderma
MedGen UID:
3767
Concept ID:
C0011606
Disease or Syndrome
An inflammatory exfoliative dermatosis involving nearly all of the surface of the skin. Erythroderma develops suddenly. A patchy erythema may generalize and spread to affect most of the skin. Scaling may appear in 2-6 days and be accompanied by hot, red, dry skin, malaise, and fever.
Ectropion
MedGen UID:
4448
Concept ID:
C0013592
Disease or Syndrome
An outward turning (eversion) or rotation of the eyelid margin.
Hypertrichosis
MedGen UID:
43787
Concept ID:
C0020555
Disease or Syndrome
Hypertrichosis is increased hair growth that is abnormal in quantity or location.
Ichthyosis
MedGen UID:
7002
Concept ID:
C0020757
Disease or Syndrome
An abnormality of the skin characterized the presence of excessive amounts of dry surface scales on the skin resulting from an abnormality of keratinization.
Pruritus
MedGen UID:
19534
Concept ID:
C0033774
Sign or Symptom
Pruritus is an itch or a sensation that makes a person want to scratch. This term refers to an abnormally increased disposition to experience pruritus.
Congenital nonbullous ichthyosiform erythroderma
MedGen UID:
38180
Concept ID:
C0079154
Disease or Syndrome
The term collodion baby applies to newborns who appear to have an extra layer of skin (known as a collodion membrane) that has a collodion-like quality. It is a descriptive term, not a specific diagnosis or disorder (as such, it is a syndrome). Affected babies are born in a collodion membrane, a shiny waxy outer layer to the skin. This is shed 10-14 days after birth, revealing the main symptom of the disease, extensive scaling of the skin caused by hyperkeratosis. With increasing age, the scaling tends to be concentrated around joints in areas such as the groin, the armpits, the inside of the elbow and the neck. The scales often tile the skin and may resemble fish scales.
Scaling skin
MedGen UID:
472970
Concept ID:
C0237849
Finding
Refers to the loss of the outer layer of the epidermis in large, scale-like flakes.
Hypoplastic nipples
MedGen UID:
98156
Concept ID:
C0432355
Congenital Abnormality
Underdevelopment of the nipple.
Nystagmus
MedGen UID:
45166
Concept ID:
C0028738
Disease or Syndrome
Rhythmic, involuntary oscillations of one or both eyes related to abnormality in fixation, conjugate gaze, or vestibular mechanisms.
Strabismus
MedGen UID:
21337
Concept ID:
C0038379
Disease or Syndrome
A misalignment of the eyes so that the visual axes deviate from bifoveal fixation. The classification of strabismus may be based on a number of features including the relative position of the eyes, whether the deviation is latent or manifest, intermittent or constant, concomitant or otherwise and according to the age of onset and the relevance of any associated refractive error.
