Endobronchial nocardiosis associated with broncholithiasis.

Pulmonary nocardiosis is a rare respiratory infection which commonly affects immunocompromised patients but also in immunocompetent hosts. The clinical manifestation is variable and endobronchial nocardiosis is a very rare condition. We report a case of endobronchial nocardiosis associated with the presence of a broncholith. The pathogenesis and the treatment of this condition are discussed below.
