Recurrent endobronchial actinomycosis following an interventional procedure.

Actinomycosis is an indolent, slowly progressive infection caused by anaerobic or microaerophilic bacteria, primarily from the genus Actinomyces. Thoracic involvement is observed in approximately 15% of cases of infection with actinomycosis. Here, we present a case of a 61-year-old male who presented with recurrent endobronchial actinomycosis. The case is being presented because of its rarity on three counts - endobronchial involvement, which is uncommon, recurrence in different sites in the bronchial tree, which is even rarer and development of the disease following an endobronchial procedure.
