[Dirofilariasis--Dirofilaria repens--first time described in Polish patients].

In this paper the first cases of human dirofilariasis in Poland are presented. The clinical manifestations were typical subcutaneous nodules with the adult worm (D. repens) in the center. Past medical history of the 5 patients revealed their trips to endemic countries, so the imported infection was considered. However 2 of these cases were difficult to interpret. It is unclear whether the infections should be considered endemic or imported, because of patients' short visits abroad which happened long time (10 years) ago.
