A Case of Infection in Man with Dirofilaria *

Abstract

Summary An adult female Dirofilaria tenuis was removed by biopsy from the subcutaneous tissue of the right thigh of a 39-year-old white man of McComb, Mississippi. The diagnosis was made preoperatively on the basis of peripheral-blood eosinophilia, a history of a migrating lesion, and presence of anti-filarial antibodies. The worm was found to contain microfilariae. It is unknown whether the multiple lesions successively noted by the patient represented the effects of a single migrating worm or of two or more. There has been no recurrence since surgical removal of the single worm.
