Podoconiosis is a form of lymphoedema (swelling) and is recognised as one of the WHO Neglected Tropical Diseases. This disease of the lymphatic vessels of the lower limb is caused by chronic exposure to irritant soils, such as volcanic red soil. It is most frequently seen in the highland areas of Africa, India, and Central America. The highest prevalence is seen in Uganda, Tanzania, Kenya, Rwanda, Burundi, Sudan, and Ethiopia and it is estimated to affect four million people worldwide. The incidence of podoconiosis increases with age, likely due to cumulative exposure to irritant soil. It is very rare to see podoconiosis in the 0-5 year old age group.
