[Stephanofilariasis in humans: occurrence and transmission mechanisms].

This work describes the occurrence of the helminth Stephanofilaria spp in ulcerative nodular dermatitis in humans. The ulcers observed presented a variety of sizes and some years of existence. It is believed that the presence of this parasite, which affects several domestic and wild animal species, may harm human health through lesions produced in venous and lymphatic vessels that reduce blood circulation and retard the healing process. The cycle of this parasite in humans is also described.
