A 60-year-old temporary Israeli resident travelled to Arizona, developed an influenzalike infection, and returned with a space-occupying lesion in the lung. Since the patient was a heavy smoker, lung cancer was suspected and he was operated on. A granuloma was reported on frozen sections, and Coccidioides immitis was revealed on stained preparations and by microbiological investigation. Coccidioidomycosis is unusual in Israel; therefore, it is important to be aware of this mycosis in patients who have a history of recent visits to areas of endemicity in North America, Central America, and South America.
