Why Elephantiasis mostly appear in legs? Is there any specific reason for that ?

Answer 1

A tricky question that is not as straightforward as it seems at first! Clearly the swelling results from blockage of lyphatics and other circulation, and this is most often the result of filarial infection. BUT- the filaria do not enter the feet like so many other worms, instead they are tranmitted by mosquito bites. So, there is no clear reason why filarial infection should result in the preferential swelling of the lower extremities.

Unless- 1. it is only a matter of the hydrostatic pressure on the obstructed lymphatics which increases the swelling- this may be the case in dependent areas. OR 2. Other challenges to lymphatic drainage of the lower extremeities combines with the filarial obstruction of lymphatics to produce more backup of the lower extremities. This latter idea is recently supported by studies on the red clay in parts of Africa which abrades the foot and must be carried up the lymphatics to clear- it also predisposes to Staph infection which furhter clogs lymphatics.

Answer 2

There is no specific reason why Elephantiasis appears mostly in legs. Actually, it is wherever the mosquito harboring the parasite Wuchereria bancrofti or Brugia malayi bites. Some even have it in the genital area.According to research in some parts of Africa where Elephantiasis is commom, they say the red soil containing the parasite may enter the person's lymphatic system through traumatic entry on their foot ( most of the natives are barefooted) thus explaning why most of them have it on their legs.

Answer 3

bacause of increased of lymphatic vessels in the legs

Answer 4

there's no specific reasons,, the site where the mosquito bit you is the site where it will enlarge
