Vitamin E deficiency and thrombocytosis in Caffey's disease

Area of Science:

• Pediatrics
• Hematology
• Genetics

Background:

• Infantile cortical hyperostosis (ICH), also known as Caffey disease, is a rare disorder characterized by bone overgrowth.
• The etiology of ICH is not fully understood, but genetic factors and inflammatory processes are suspected.
• Ocular manifestations such as ptosis and periorbital edema can occur in infants with ICH.

Observation:

• This report details an infant presenting with ptosis and periorbital edema.
• Clinical examination revealed signs suggestive of infantile cortical hyperostosis.
• Associated laboratory findings were noted.

Findings:

• The infant was diagnosed with infantile cortical hyperostosis.
• Laboratory investigations revealed thrombocytosis (elevated platelet count).
• Elevated immunoglobulin M (IgM) levels and vitamin E deficiency were also identified.

Implications:

• This case highlights a unique presentation of infantile cortical hyperostosis with specific hematological and biochemical abnormalities.
• The co-occurrence of thrombocytosis, raised IgM, and vitamin E deficiency in ICH warrants further investigation.
• Understanding these associations may lead to improved diagnostic approaches and targeted therapies for affected infants.
