Abstract

A wide variety of pulmonary lesions may be caused by coccidioidomycosis. Suspicion of coccidioidomycosis may be substantiated by careful clinical-epidemiological histories. The first laboratory procedure should be a coccidioidin skin test. If the reaction to the test is positive, serological tests are next. Also, if there is no reaction to coccidioidin, serological tests are still indicated if dissemination is suspected. The more severe the infection, the greater the probability of establishing a diagnosis serologically. In only three-fifths of patients with coccidioidal cavities can the diagnosis be fixed serologically. In such patients if differential skin tests are not conclusive, attempt should be made to recover the fungus. However, this is accompanied by great risk of laboratory infection. Eosinophilia and accelerated erythrocyte sedimentation are only circumstantial items of evidence, as is the appearance of the pulmonary roentgenogram.
