Elephantiasis, often incorrectly called elephantitis, is the enlargement and hardening of limbs or body parts due to tissue swelling (edema).[1][2] It is characterised by edema, hypertrophy, and fibrosis of skin and subcutaneous tissues, due to obstruction of lymphatic vessels (lymphedema).[2] It may affect the genitalia.[2] The term elephantiasis is often used in reference to (symptoms caused by) parasitic worm infections,[1][2] but may refer to a variety of diseases that swell parts of the subject's body to exceptionally massive proportions.[2]
Cause
[edit]Some conditions that present with elephantiasis include:
- Elephantiasis nostras, due to longstanding chronic lymphangitis.[citation needed]
- 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.[3]
- Nonfilarial elephantiasis (or podoconiosis), an immune disease affecting the lymph vessels[citation needed]
- Leishmaniasis[2]
- Elephantiasis, Grade 3 lymphedema which may occur in people with breast cancer[4]
- Genital elephantiasis, result of lymphogranuloma venereum[citation needed]
- Proteus syndrome, a genetic disorder best known as the condition possibly experienced by Joseph Merrick, the so-called "Elephant Man"[citation needed]
Other causes may include:
- Repeated streptococcal infection[2]
- Lymphadenectomy[2]
- Hereditary birth defects[2]
- Pretibial myxedema
Other diseases, such as the rare Klippel–Trénaunay syndrome, can initially be misdiagnosed as elephantiasis.
