[Bullous pemphigoid in an infant]

Area of Science:

• Dermatology
• Immunology
• Pediatrics

Background:

• Bullous pemphigoid is an acquired autoimmune blistering disease primarily affecting the elderly.
• It is exceptionally rare in infants, with only ten cases previously documented in medical literature.

Observation:

• A previously healthy six-month-old infant presented with a six-day history of erythematous, vesico-bullous cutaneous lesions.
• Clinical presentation suggested an autoimmune blistering disorder.

Findings:

• Histopathological examination and direct immunofluorescence studies confirmed the diagnosis of bullous pemphigoid.
• The infant exhibited characteristic immunopathological findings of the disease.

Implications:

• This case expands the limited literature on infantile bullous pemphigoid, highlighting its occurrence in very young children.
• Successful treatment with systemic and topical corticosteroids demonstrates therapeutic efficacy in this pediatric demographic.
• Further research into the specific triggers and long-term outcomes of infantile bullous pemphigoid is warranted.
