Human infection with Dirofilaria

Human infection with Dirofilaria is rare. Fewer than 100 cases have been reported in the world's literature. Among the cases reported in the United States, most of the patients have been from Florida and Louisiana. The majority of the patients had a single lesion that involved either the skin or the lung. The case presented here is unusual because the patient had two skin lesions, and because the condition occurred in a patient who lived in the North-Central portion of the United States (Upper Michigan).
