Dermato-Lymphangitis in Filariasis Resembles Infected Chronic Venous Insufficiency: Two Case Reports and Review of Literature

Abstract

Chronic lower limb swelling is frequently encountered in clinical practice. Secondary lymphoedema and chronic venous insufficiency are two frequent causes of chronic lower limb swelling. The most common form of secondary lymphoedema worldwide is filariasis, due to Wuchereria bancrofti. Chronic inflammation and fibrosis are histological hallmarks of lymphoedema. Chronic venous insufficiency refers to venous dilation and venous reflux of long duration. The classical signs include minimal superficial dilation with associated skin changes and ulceration. Both the conditions mimic each other although the treatment is different. The diagnosis need to be confirmed prior to institution of treatment. We present below two cases of chronic lower limb swelling with a review of literature.
