Overview
Lymphatic filariasis must be differentiated from other causes of lower limb edema, such as chronic venous insufficiency, acute deep venous thrombosis, lipedema, myxedema, cellulitis and causes of generalized edema.
Differentiating filariasis from other diseases
Lymphatic filariasis must be differentiated from other causes of lower limb edema like chronic venous insufficiency, acute deep venous thrombosis, lipedema, myxedema, cellulitis and causes of generalized edema.
