Pseudo-tumor of the scrotum, a rare clinical presentation of dirofilariasis: a report of two autochtonous cases due to Dirofilaria repens.

In Europe, human dirofilariasis refers to a group of autochtonous parasitic infections caused by tissue nematodes of the genus Dirofilaria, responsible for two distinct clinical presentations: Dirofilaria immitis usually presenting as pulmonary lesions and Dirofilaria repens as subcutaneous nodules. Rare in humans, genital involvement manifests itself as pseudotumor nodules affecting the scrotum, epididymis, or spermatic cord. We report on two cases of Dirofilaria repens infections, involving the spermatic cord and epididymis.
