• Pulmonary actinomycosis occurred in a patient who was believed to have either tuberculosis or malignant neoplasm. Rapid clinical and roentgenographic improvement followed two weeks of therapy with isoniazid and rifampin. This case demonstrates that the improvement that may occur when pulmonary actinomycosis is treated with rifampin may erroneously reinforce the suspicion of tuberculosis.
