title: Coccidioidomycosis: office diagnosis and treatment.
abstract: Although most patients with coccidioidomycosis are asymptomatic, up to 40 percent develop fatigue, cough, chest pain and fever. Erythema nodosum is often present. Chest radiographs may be normal or may show hilar adenopathy, infiltrates, pulmonary nodules or thin-walled cavities. The spherulin skin test is usually positive within three weeks of infection. Specific IgM [corrected] antibodies may be detected early in the course; IgG [corrected] antibodies develop after two to three months. In most patients, the disease has a self-limited course and requires no specific therapy. A few patients develop progressive pulmonary or disseminated disease. Extrapulmonary sites of disease include the skin, the skeleton and, rarely, the nervous system. Amphotericin B and ketoconazole are used to treat disseminated disease. Because coccidioidomycosis is caused by a fungus that is endemic in the Southwest, a travel history should be elicited from patients with persistent pulmonary symptoms.
