Bullous Pemphigoid

This is a chronic, acquired autoimmune, sub-epidermal blistering disease.

Presentation:

• Typically affects the elderly

• Severe itch and large, tense bullae (fluid-filled blisters), which rupture to form crusted erosions

• Usually involves flexor surfaces of limbs, and it may be localised to one area, or widespread on the trunk and proximal limbs

  
  

A biopsy is usually required for a diagnosis.

It's managed with systemic corticosteroids.
