Macular Rash, Thrombocytopenia, and Hyperbilirubinemia in a Preterm Infant

Area of Science:

• Endocrinology
• Neonatology
• Immunology

Background:

• Neonatal hyperthyroidism is a rare condition typically resulting from maternal thyroid receptor antibodies crossing the placenta.
• It can manifest in newborns with symptoms such as cholestasis, prematurity, and cardiomegaly.

Observation:

• A preterm infant presented with clinical signs of cholestasis, cardiomegaly, and a macularpapular rash.
• The rash initially raised suspicion for congenital infection, highlighting diagnostic challenges.

Findings:

• The infant was diagnosed with neonatal Graves' disease, a form of neonatal hyperthyroidism.
• This diagnosis underscores the importance of considering autoimmune etiologies in neonates with suggestive symptoms.

Implications:

• Early recognition of neonatal Graves' disease is vital for timely intervention and management.
• This case emphasizes the need for heightened awareness among clinicians to differentiate Graves' disease from congenital infections in neonates.
