Pulmonary coccidioidomycosis after a renal transplant in a nonendemic region.

Coccidioidomycosis is a fungal infection caused by the Coccidioides species, endemic to the southwestern United States. In healthy people, manifestations range mainly from asymptomatic to mild influenza-like signs, whereas in immunosuppressed patients (eg, transplant recipients) this infection is often a severe disseminated disease. We report a case of primary pulmonary coccidioidomycosis in a 61-year-old man with a renal transplant 7 months earlier. The patient had nonspecific symptoms of pulmonary infection, including weakness, anorexia, and weight loss. Both spherules and endospores of Coccidioides immitis were seen histologically after a transbronchial biopsy of a cavitary lesion. The patient was treated with amphotericin B. At the time of this writing (8 months), he remains disease free.
