GENERAL HISTOLOGY

Detailed explanation-1: -Lymphedema refers to tissue swelling caused by an accumulation of protein-rich fluid that’s usually drained through the body’s lymphatic system. It most commonly affects the arms or legs, but can also occur in the chest wall, abdomen, neck and genitals. Lymph nodes are an important part of your lymphatic system.

Detailed explanation-2: -While the most common cause of lymphedema worldwide is filariasis caused by infection by Wuchereria bancrofti, in developed countries, most secondary lymphedema cases are due to malignancy or related to the treatment of malignancy.

Detailed explanation-3: -Primary and secondary lymphedema are the two main types of lymphedema. In both cases, missing or damaged lymph vessels or lymph nodes cause a blockage of the lymphatic system. The protein-rich fluid called lymph or lymphatic fluid is unable to drain properly and collects in the tissues.
