Two cases of endobronchial actinomycosis that were cured by bronchoscopic removal and short-term antibiotic therapy / 대한내과학회지

ABSTRACT

Actinomycosis is an uncommon, chronic granulomatous, suppurative disease related to Actinomyces israelii, which is a natural inhabitant of the oropharyngeal cavity and the major human pathogen of actinomycosis. In the past, dramatic presentation of thoracic actinomycosis, in conjunction with prominent chest pain and cutaneous fistulas that discharge sulfur granules, has frequently been reported. However, more recent data indicate that chest wall or rib involvement is now much less common than was previously encountered. This could result in more favorable responses to short-term intravenous antibiotic therapy. Foreign-body-associated actinomycosis is a very rare type of thoracic actinomycosis. We report two cases of endobronchial actinomycosis associated with a foreign body. In both cases, the foreign body was successfully removed by bronchoscopy. Each patient was treated with antibiotics for about 70 days. The duration of antibiotic therapy was relatively short, as compared to conventional therapy. Nevertheless, there was no recurrence or complications over 1 year.
