Bullous pemphigoid
Etiology, pathogenesis
  • autoimmune disease: circulating IgG antibodies bind to lamina lucida of basement membrane
  • antibody binding causes blister formation
Clinical signs
  • elder patients (over 70 years)
  • the trunk, extremities, seldom the head, mucous membranes
  • tense blisters on reddened skin
  • chronic urticarial lesions
  • pruritus, healing without scars

Histology

Subepidermal blisters, roof formed by almost normal epidermis. Vacuolar degeneration of the basal layer. Eosinophils variably admixtured in the superficial dermal infiltrate, often enter the epidermis and usually are present within the bulla (but not in cell poor variant). The base of the blister reepitelises quickly and the blister sometimes becomes intraepidermal. Immunofluorescence: linear deposits of IgG and C3 along the basement membrane.
