title: Bronchomalacia occurring in monozygotic twins--further information about its inheritance.
abstract: We report left main-stem bronchomalacia occurring in monozygotic twins that became symptomatic during infancy. This phenomenon has not previously been reported to occur in twins. Little is known about the aetiology of primary bronchomalacia, but this occurrence suggests that there may be a significant genetic component in some cases.
  
  
  CONCLUSIONS
  Left main-stem bronchomalacia occurring in monozygotic twins suggests that there may be a significant genetic component in some cases and provides further information about the inheritance of this condition.
