Invasive tracheobronchial aspergillosis in an immunocompetent person.

Tracheobronchial involvement is an uncommon form of invasive pulmonary aspergillosis and is found mainly in immunocompromised individuals such as patients with leukemia and prolonged granulocytopenia due to cytotoxic therapy, organ transplant recipients receiving high-dose corticosteroids, or patients with chronic granulomatous diseases. Rarely, such a pattern can also be seen in immunocompetent persons or can involve atypical sites such as the paranasal sinuses, skin, and the tracheobronchial tree. Occasionally, these patients require a prolonged course of antifungal agents. We report a case of aspergillosis involving the tracheobronchial tree in an immunocompetent young male that presented a diagnostic dilemma.
