Harlequin ichthyosis--difficulties in prenatal diagnosis

Area of Science:

• Dermatology
• Genetics
• Neonatology

Background:

• Ichthyoses are genodermatoses defined by epidermal hyperkeratosis and desquamation.
• Harlequin ichthyosis, the most severe form, is an autosomal recessive congenital disorder.
• Epidermal dysfunction in harlequin ichthyosis originates prenatally, often leading to severe neonatal conditions.

Observation:

• A case of harlequin ichthyosis is presented in a male infant born to healthy parents with no family history of congenital anomalies.
• Prenatal sonography at 26 weeks gestation identified fetal facial anomalies, but not the specific diagnosis of harlequin ichthyosis.
• The infant was born at 37 weeks gestation, exhibiting classic harlequin ichthyosis features at birth.

Findings:

• The neonate required intensive care following birth.
• The infant survived and was reported to be in good condition at 6 months of age.
• This case underscores the impact of advanced neonatal care on outcomes for infants with harlequin ichthyosis.

Implications:

• Improved neonatal care and treatment strategies can significantly enhance the quality of life and survival rates for infants with harlequin ichthyosis.
• This case contributes to the understanding of harlequin ichthyosis management and outcomes.
• Early recognition of potential congenital anomalies during prenatal screening is crucial, even if a definitive diagnosis is not immediately established.
