What Is Lymphedema?

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.

Lymphedema Stages

Stage 0 (Latency stage) 

• The patient is considered “at-risk” for lymphedema development due to injury to the lymphatic vessels but does not present with outward signs of edema?.
• Includes patients with breast cancer who have undergone sentinel lymph node biopsy? and or radiation but have not yet developed swelling?.
• Lymphatic transport capacity has been reduced, which predisposes the patient to lymphatic overload and resultant edema?.

Stage 1 (Spontaneous)

• Reversible
• Has pitting edema?
• Swelling? at this stage is soft and may respond to elevation

Stage 2 (Spontaneously irreversible)

• Has tissue chronic? injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।" data-rx-term="fibrosis" data-rx-definition="Fibrosis means excess scar-like tissue formation after chronic injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।">fibrosis?/induration
• Swelling? does not respond to elevation
• Skin and tissue thickening occurs as the limb volume increases
• Pitting may be present but may be difficult to assess due to tissue and or skin chronic? injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।" data-rx-term="fibrosis" data-rx-definition="Fibrosis means excess scar-like tissue formation after chronic injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।">fibrosis?

Stage 3 (Lymphostatic elephantiasis)

• Show the following:

  • Pitting edema?
  • chronic? injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।" data-rx-term="fibrosis" data-rx-definition="Fibrosis means excess scar-like tissue formation after chronic injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।">Fibrosis?
  • Skin changes
  • During this stage, papillomas may form, infections/cellulitis may occur, and the skin becomes dry

The Stemmer sign may not be present in Stages 1 or 2.

Types of Lymphedema:

1. Primary Lymphedema: This occurs when there’s a problem with the lymphatic system that’s present from birth.
2. Secondary Lymphedema: This happens when something damages the lymphatic system later in life, such as surgery, infection?, or radiation therapy.

Pathophysiology

Primary lymphedema is associated with dysplasia of the lymphatic system and can also develop with conditions of other vascular abnormalities, including Klippel-Trenaunay-Weber syndrome,[rx], and Turner syndrome.[rx] Primary lymphedema is marked by hyperplasia, hypoplasia, or aplasia of the lymphatic vessels.

Secondary lymphedema develops due to damage or dysfunction of the normally functioning lymphatic system. Although cancer treatments, including oncologic surgical procedures such as axillary lymph node dissection and excision in breast cancer and radiation treatment, are the most common cause of lymphedema in the United States, filariasis is the most common cause of secondary lymphedema globally.[rx] Filariasis is the direct infestation of lymph nodes by the parasite?, Wuchereria bancrofti. The spread of the parasite? by mosquitos affects millions of people in the tropic and subtropic regions of Asia, Africa, the Western Pacific, and Central and South America.

Oncologic surgical procedures such as sentinel lymph node biopsy? and radical dissection that require excision of regional lymph nodes or vessels can lead to the development of secondary lymphedema. Other surgical procedures linked to secondary lymphedema development include peripheral vascular surgery, burn scar excision, vein stripping, and lipectomy.

Nonsurgical causes of lymphedema include recurrent tumors or malignancy that have metastasized to the lymph nodes; obstructive lesions within the lymphatic system; infected and/or traumatized lymphatic vessels; scar tissue obliterating the lumen of the lymphatic vessels. Edema? from deep venous thrombosis? (DVT) or nonobstructive causes of chronic? venous insufficiency at the extremities may lead to secondary lymphedema.

Although there is no definitive cure for lymphedema, with proper diagnosis? and management, its progression and potential complications can successfully be managed.[rx]

Causes of Lymphedema:

1. Surgery: Especially when lymph nodes are removed or damaged during surgery, like in cancer treatment.
2. Radiation Therapy: Used to treat cancer, but it can also damage the lymphatic system.
3. Infection?: Infections like cellulitis can block lymphatic vessels.
4. Injury: Trauma to the lymphatic system can cause swelling?.
5. Obesity: Excess weight can put pressure on lymphatic vessels.
6. Genetics: Some people may inherit a predisposition to lymphedema.
7. Filariasis: A parasitic infection? transmitted by mosquitoes, common in tropical regions.
8. Deep Vein Thrombosis? (DVT): Blood clots in the veins can obstruct lymphatic flow.
9. Inflammatory Conditions: Conditions like arthritis?: Rheumatoid arthritis is an autoimmune? joint disease causing infection?, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation?, pain, and swelling. সহজ বাংলা: রোগপ্রতিরোধ ব্যবস্থার ভুল আক্রমণে জয়েন্টের প্রদাহ।" data-rx-term="rheumatoid arthritis" data-rx-definition="Rheumatoid arthritis is an autoimmune joint disease causing inflammation, pain, and swelling. সহজ বাংলা: রোগপ্রতিরোধ ব্যবস্থার ভুল আক্রমণে জয়েন্টের প্রদাহ।">rheumatoid arthritis? or lupus can lead to inflammation that affects the lymphatic system.

Diagnostic Tests for Lymphedema:

History

• Thorough family history is essential if primary lymphedema is suspected. It is important to evaluate if other family members, usually from an earlier generation, suffer or have suffered from swollen feet, ankles, and legs due to an “unknown cause.”
• Cancer
• Injuries
• Severe burns
• Edema, especially of an extremity
• Hyperkeratosis: skin becomes scaly and thickens
• Lymphangioma: small blisters and bumps develop on the skin
• Lymphorrhea: lymph fluid leaks from the skin

Physical Exam

Skin

• Dryness, increased thickness, hyperkeratosis, lymphangiomas (blisters containing lymph fluid), abnormally warm or hot, unusually dark skin, and any nodules are all lymphedema indicators.
• Papillomatosis, a cobblestone appearance of the skin, may also be present; it results from dilated and distended lymph vessels enveloped in fibrotic tissue.[rx]
• Hyperkeratosis
• Lymphangioma
• Lymphorrhea
• Positive Stemmer’s sign: inability to pinch a fold of skin at the root of the second toe suggests lymphedema[rx]

Extremity

• Size: Less than a 20% difference in the affected extremity is considered mild or moderate, and greater than 20% is considered severe.[rx]
