  • Bullae evolve over weeks to months

Clinical Presentation

  • Bullae commonly occur in the axillae, abdomen, inner thighs, flexural forearms, and lower legs[1]
  • May be intensely pruritic
  • Nikolsky sign negative
  • Involves mucosa in 10-25%, may limit PO intake

Differential Diagnosis

Vesiculobullous rashes




  • Antihistamine for pruritis
  • Anti-inflammatory agents options
    • Oral Corticosteroids such as Prednisone 50mg PO daily
    • Tetracycline 1.5-2 g/day with Nicotinamide 1.5-2 g/day
    • Topical high potency steroids such as Clobetasol
  • Immunosuppressants (eg, azathioprine, methotrexate, mycophenolate mofetil, cyclophosphamide).
  • Most will require therapy for 6-60 months, mortality asso w disease usually secondary to medications

Topical corticosteroids may offer similar treatment effect as oral steroids with less systemic effects.[2][3][4]
