Clinical Information
  • A group of chronic skin disorders in which fluid-filled blisters form on the skin and mucosa (the moist, inner lining of some organs and body cavities). Epidermolysis bullosa is inherited and usually starts at birth. Patients with epidermolysis bullosa may be at increased risk of squamous cell cancer of the skin.
  • An autosomal recessive inherited skin disorder caused by mutations in the genes encoding keratins 5 and 14, collagen vii or laminin 5. It is characterized by skin fragility and the formation of blisters. The blisters may become large and ulcerated, resulting in skin infections and loss of body fluids.
  • Group of genetically determined disorders characterized by the blistering of skin and mucosae. There are four major forms: acquired, simple, junctional, and dystrophic. Each of the latter three has several varieties.
  • Inherited chronic noninflammatory skin disease manifested by vesicles, large bullae (blisters), and skin erosions which often result from trauma.
