Area of Science:

  • Dermatology
  • Autoimmunology
  • Immunodermatology

Background:

  • Bullous pemphigoid (BP) is an autoimmune blistering disease primarily affecting the elderly.
  • It typically presents with tense blisters on erythematous or normal-appearing skin.
  • Clinical variants of BP are recognized, but atypical presentations can occur.

Observation:

  • Two cases of bullous pemphigoid are presented, initially mimicking subacute prurigo.
  • Patients exhibited intensely pruritic, excoriated papules for months without developing blisters.
  • Histopathology revealed chronic dermatitis, not typical blistering lesions.

Findings:

  • Indirect immunofluorescence detected antibodies binding to the roof of artificial blisters in patient sera.
  • Perilesional skin biopsies showed linear IgG or C3 deposits in the basement membrane zone.

  • Immunoblotting confirmed antibody binding to the 230-kD major bullous pemphigoid antigen.

    • Implications:

    • These findings suggest that bullous pemphigoid can manifest with pruritic papules, challenging traditional diagnostic criteria.
    • Recognition of this variant is crucial for accurate diagnosis and timely management of BP.
    • The study expands the understanding of the clinical spectrum of bullous pemphigoid.
