Summary
Bullous pemphigoid (BP), a rare blistering disease in children, presented atypically with herpetiform lesions in a pediatric patient. Diagnosis was confirmed by immunofluorescence and autoantibodies targeting the BP180 antigen.
Area of Science:
- Immunodermatology
- Pediatric Autoimmune Diseases
Background:
- Bullous pemphigoid (BP) is an acquired autoimmune blistering disease typically affecting the elderly.
- Pediatric bullous pemphigoid is rare, and herpetiform presentations are even less common, posing diagnostic challenges.
Observation:
- A 16-year-old African-American male presented with generalized vesicular eruptions.
- The patient's lesions were distinctly herpetiform, mimicking other vesicular dermatoses.
- Initial diagnosis and therapy were complicated by the unusual morphology of the lesions.
Findings:
- Direct and indirect immunofluorescence confirmed the diagnosis of bullous pemphigoid.
- Immunoblotting and ELISA identified autoantibodies against the BP180 antigen.
- These autoantibodies targeted the immunodominant NC16A domain of BP180, consistent with typical BP autoantibody profiles.
Implications:
- This case highlights the importance of considering bullous pemphigoid in the differential diagnosis of pediatric patients with unusual vesicular eruptions.
- The herpetiform presentation underscores the variability of BP morphology, even in pediatric cases.
- Accurate diagnosis through immunofluorescence and serological testing is crucial for appropriate management of pediatric bullous pemphigoid.
