Bullous diseases are a subset of the large inflammatory skin diseases category. Dermatopathologists help diagnose it.

An introduction to skin pathology is in the dermatopathology article. An introduction to inflammatory skin lesions in the non-malignant skin disease article.

Bullous disease of the lung is dealt with in lung bullae.

  • AKA Hailey-Hailey disease. Was described by two brothers - that's why it is Hailey-Hailey.[12]

General

  • Genetic - autosomal dominant with incomplete penetration.[12]
    • Desmosomal defect - due to mutation in the gene ATP2C1.[12]

Porphyria cutanea tarda

General

Etiology:

  • Genetic, autosomal dominant.

Epidermolysis bullosa

General

  • A group of inherited, bullous disorders.
  • Bullae form due to slight mechanical trauma.

Three major groupings:[17]

  1. Epidermolysis bullosa simplex (intraepidermal disease).
  2. Junctional epidermolysis bullosa (separation at DE junction; specifically central portion (lamina lucida)).
  3. Dystrophic epidermolysis bullosa (separation at DE junction; specifically deep to lamina densa).

Microscopic

Depends on subtype - either intraepidermal or subepidermal.

Grover disease

  • AKA transient acantholytic dermatosis.

General

  • Cause not known.
  • Associated with sun damaged skin, hospitalization and fever.[18]

Clinical:[19]

  • Pruritis (itchy).
  • Usually self-limited.
  • Treatment for symptoms.

Gross

  • Usually small ~ 50% less than 2 mm.[20]
  • Typically chest and back.[21]
