Summary
Hyper-IgM syndrome causes low IgG, IgA, and IgE but normal or high IgM. This case highlights recurrent diaper area ulcers in a child with this rare immunodeficiency.
Area of Science:
- Immunology
- Pediatrics
Background:
- Hyper-IgM syndrome is a rare primary immunodeficiency.
- Characterized by defective immunoglobulin class switching, leading to low IgG, IgA, and IgE with normal or elevated IgM.
Observation:
- A 14-month-old girl presented with recurrent cutaneous ulcers.
- Ulcerations were exclusively localized to the diaper area.
Findings:
- The patient was diagnosed with Hyper-IgM syndrome.
- This case presents an unusual manifestation of cutaneous ulcers in the diaper area.
Implications:
- Highlights the diverse clinical presentations of Hyper-IgM syndrome.
- Suggests considering Hyper-IgM syndrome in pediatric patients with unexplained recurrent cutaneous ulcers, even if localized.
