Bronchopleural cutaneous fistula due to Eikenella corrodens.
OBJECTIVE
The aim of this paper is to review the subject and to report on and discuss a case of bronchopleural cutaneous fistula due to Eikenella corrodens.


METHODS
A 16-year-old girl was brought to our hospital with fever and blood-tinged sputum 2 weeks prior to her admission. She suffered from neurologic sequelae of herpetic encephalitis and had been bed-ridden since 5 years of age. A longitudinal paraspinal soft mass had been noted in the previous week by her mother. She had been given oral feeding despite frequent choking for the past few years. On palpation, the mass can be squeezed to follow the least resistance of subcutaneous space longitudinally extending to the lower thoracic region. Chest computed tomography scan revealed right lower lobe necrotizing pneumonitis and a pleuro-cutaneous fistula leading to the subcutaneous air locules. A protracted course of antibiotics was prescribed and subcutaneous air trapping decreased in size over 8 weeks.


CONCLUSIONS
Eikenella corrodens has increasingly been implicated as a potential causative pathogen in pleuropulmonary infections. Pleuro-cutaneous fistula and abscess formation complicating empyema and necrotizing pneumonitis due to E. corrodens infection have not been reported. A bulging thoracic subcutaneous lesion waxes and wanes with respiration suggest the possibility of a pleruo-cutaneous fistula. Treatment of Eikenella empyema using antibiotics without surgical decortication requires a prolonged course of antibiotic therapy.
