To the editor: The dog heartworm (Dirofilaria immitis) can infest humans. Infestation is most frequent in the lung, and the disease usually presents as an asymptomatic nodule seen on a routine chest film (1, 2). All previously reported cases have been in patients with no known previous or concomitant malignancies. We report a case of pulmonary dirofilariasis in a patient who had sucessfully completed therapy for small-cell (oat cell) lung cancer, in whom the major issue was the benign or malignant nature of the lesion.
