Coccidioides immitis is a causative agent of coccidioidomycosis, which is one of the most dreadful mycosis because of its infectious and pathogenic nature. The endemic areas are in the southwestern parts of the United States and other semi-arid regions throughout the Western Hemisphere. During the early 1990s, the incidence of coccidioidomycosis in California increased dramatically, resulting in recognition for this mycosis as a reemerging infectious disease in the United States. The patients included a large number of non-informed visitors from non-endemic countries. Our report is on an imported case of primary pulmonary coccidioidomycosis.
A 35-year-old Japanese male, after living in the United States for nine months, suffered from a combination of headache and fever. He was given a serological examination, and a chest radiograph in Phoenix, Arizona in the United States and was diagnosed as coccidioidomycosis. A daily dosage of 400mg of fluconazole was administered and he returned to Japan. His headache and skin rash persisted and he was admitted to our hospital to evaluate the severity of his disease. There were no fungi cultured from neither bronchoalveolar nor cerebrospinal fluid and he was discharged. The patient had been treated with fluconazole and his symptoms, high-resolution CT and serological antibody titer were monitored. After 18months, his clinical and radiological evolution was favorable and his serological IgM titer was below its sensitivity medication was stopped and there were no relapses.
