==Cause==
Some conditions that present with elephantiasis include the following:
* [[Elephantiasis nostras]], due to longstanding chronic [[lymphangitis]].{{Citation needed|date=June 2018}}
* [[Elephantiasis tropica]] (known as lymphatic filariasis), caused by a number of parasitic worms, particularly ''[[Wuchereria bancrofti]]''. More than 120 million people, mostly in Africa and Southeast Asia, are affected.<ref>{{cite web|last1=Carlson|first1=Emily|title=Taking the 'Bite' Out of Vector-Borne Diseases - Inside Life Science Series - National Institute of General Medical Sciences|url=https://publications.nigms.nih.gov/insidelifescience/vector-borne-diseases.html|publisher=publications.nigms.nih.gov|access-date=29 November 2016|date=27 March 2013|archive-date=28 July 2018|archive-url=https://web.archive.org/web/20180728010133/https://publications.nigms.nih.gov/insidelifescience/vector-borne-diseases.html|url-status=dead}}</ref>
* [[Nonfilarial elephantiasis]] (or podoconiosis), an immune disease affecting the lymph vessels{{Citation needed|date=June 2018}}
* [[Leishmaniasis]]<ref name=":1" />
* Elephantiasis, Grade 3 [[lymphedema]], which may occur in people with [[breast cancer]]<ref>{{cite web|title=Lymphedema|url=https://www.cancer.gov/about-cancer/treatment/side-effects/lymphedema/lymphedema-pdq |publisher=National Cancer Institute|access-date=29 November 2016|date=29 May 2015}}</ref>
* Genital elephantiasis, result of [[lymphogranuloma venereum]]{{Citation needed|date=June 2018}}
* [[Proteus syndrome]], a genetic disorder best known as the condition possibly experienced by [[Joseph Merrick]], the so-called Elephant Man{{Citation needed|date=June 2018}}

Other causes may include the following:
* Repeated streptococcal infection<ref name=":1" />
* Lymphadenectomy<ref name=":1" />
* Hereditary birth defects<ref name=":1" />
* [[Pretibial myxedema]]

Other diseases, such as the rare [[Klippel–Trénaunay syndrome]], can initially be misdiagnosed as elephantiasis.
