[Primary bronchial actinomycosis and foreign body].

This paper presents the fourth case reported on the association of primary bronchial actinomycosis and foreign body. The pathogenesis of this rare association has been linked to the low respiratory tract and a foreign body (chicken bone); it depends on its characteristics and how long it has remained lodged into the bronchial tree. The diagnosis of this case was very difficult and late. Several endoscopy procedures were required in order to detect it. Our patient has been treated successfully with parenteral penicillin in association with an original bronchoscopic procedure using a laser technique to find the foreign body and take it out of the respiratory tract. We consider that it is necessary to remember this association in every patient who suffers from recurrent pneumonia, in those who are at risk of foreign body aspiration and when the presence of an endobronchial mass is suspected.
