Lymphatic filariasis is also known as elephantiasis. Other causes of lymphedema include Kaposi sarcoma, mycetoma, and elephantiasis nostras verrucosa. Additionally, surgical treatment may be helpful for issues related to scrotal elephantiasis and hydrocele. Arsenic was recommended for over 100 illnesses including anemia, diarrhea, hydrophobia, elephantiasis, and impotence. Although elephantiasis nostras resembles the elephantiasis caused by helminths, it is not a filarial disease. Elephantiasis results when the parasites lodge in the lymphatic system. This may lead to lymph stasis (obstruction of the lymph vessels) and elephantiasis. The skin condition the disease causes is called "elephantiasis tropica" (also known as "elephantiasis arabum"). It can also occur in acromegaly, elephantiasis, and podoconiosis. Elephantiasis resulting from "B. malayi" infection typically affects the distal portions of the extremities. Thus he discovered mosquitoes as a vector for elephantiasis. However, surgery is generally ineffective at correcting elephantiasis of the limbs. The disease was known in Ancient Greece as elephantiasis (elephantiasis graecorum).
