Definition / General
  • Bronchogenic cysts presenting in the skin are very rare, with fewer than 70 cases reported
  • Most are present at birth on the precordium or overlying the suprasternal notch
  • Occasionally occur near shoulder, back, scapula, neck, abdomen or chin or present at a later age
  • Believed to form from buds or diverticula that separate from foregut during development of the tracheobronchial tree
  • May be intrapulmonary or peripheral
  • Cutaneous bronchogenic cysts may result from subsequent sequestration outside the chest cavity following fusion of the mesenchymal bars of the sternum, or from active migration prior to fusion
Clinical Features
  • 80% males
  • Variable presentation as cutaneous cystic nodule, sinus or papillomatous growth
  • Usually asymptomatic but may be tender or painful
  • Rarely are multiple
  • Treatment is surgical resection, if clinically indicated

Micro Description
  • Cutaneous bronchogenic cyst occurs within dermis or subcutaneous tissue
  • Lining is usually thrown into small folds
  • Epithelium is invariably ciliated, pseudostratified cuboidal or columnar, with mucus secreting goblet cells in 50% of cases
  • May have nonciliated cuboidal, columnar and stratified squamous epithelium
  • Smooth muscle supports the mucosa in 8% of cases
  • Lymphoid follicles are found in 25% of cases, and appear to be part of a secondary inflammatory response
  • Occasionally seromucinous glands or cartilage are present
  • Cutaneous lung tissue heterotopia, in which fully developed bronchioles and alveoli are present, is considered a variant
