The topic Bullous Recurrent Eruption you are seeking is a synonym, or alternative name, or is closely related to the medical condition Epidermolysis Bullosa (EB).

Quick Summary:

  • Epidermolysis Bullosa (EB) is a group of disorders in which there is blister formation or severe fragility of the skin and/or mucosal membranes after minimal trauma. It is usually inherited from the family (passed on to children)
  • In Epidermolysis Bullosa, mutations of the genes encoding proteins that bind the outer skin layer (epidermis) to the lower layer (dermis) is defective or nonfunctional, which leads to skin fragility. Hence, a minor injury, such as friction or rubbing, can separate the skin layers easily, resulting in painful skin tearing or blistering
  • Epidermolysis Bullosa is not a preventable condition. However, blistering and complications can be prevented to a certain extent. There is also no cure for EB. The treatment offered is symptomatic including blister wound care, use of painkillers, nutritional support, and supportive care
  • There are many variable forms of Epidermolysis Bullosa. The prognosis depends on the type of EB. Children with junctional EB usually succumb to the condition within the first year. Children with other forms of EB can expect to have normal lifespans with appropriate care

Many types of Epidermolysis Bullosa have been identified; of which, the following 3 are the major types:

  • Epidermolysis Bullosa Simplex:
    • It is the most common type, accounting for over 90% of EB individuals (in the US)
    • The condition is inherited in an autosomal dominant manner
    • It is milder compared to other EB types, and usually no scarring is seen
    • Separation involves the epidermis of the skin
    • The mutated genes encode proteins Keratin 5, Keratin 15, and Plectin
    • It is usually present at birth or during infancy
    • The condition commonly affects the palms of the hands and soles of the feet
  • Dystrophic Epidermolysis Bullosa:
    • It can be inherited in an autosomal dominant or autosomal recessive manner. Recessive inheritance is more severe
    • The mutated genes encode collagen (type VII) proteins
    • It can be mild to severe in presentation
    • Separation involves the very uppermost dermis of the skin
  • Junctional Epidermolysis Bullosa:
    • It is the most severe form of EB
    • Separation involves the junction of epidermis and skin
    • The mutated genes encode proteins Plectin, Laminin 332, and a6b4 Integrin
    • The condition presents itself at birth
  • Epidermolysis Bullosa Acquisita is an acquired form of EB. It is a rare condition that is considered to occur due to autoimmune mechanisms (when the body immunity fights against its own tissues)
