Key Points
Immunosuppression and chronic pulmonary disease are predisposing factors, but up to 30% of patients have no preexisting disease. Pneumonia is typical, but skin and central nervous system infections are common; hematogenous spread can involve almost any organ. Treat withtrimethoprim/sulfamethoxazole (or one of the numerous alternatives) for a prolonged duration.
