CLT Lymphedema Pathology & Staging 2

Question 1

Which tissue change in chronic lymphedema results from macrophage activity digesting accumulated proteins?

Accepted Answer

Fibrosis from chronic inflammatory response and protein degradation

Answer

Chronic protein accumulation triggers macrophages and inflammatory cells that stimulate fibroblasts, leading to progressive fibrosis that hardens the tissue.

Question 2

The Stemmer sign is a clinical test for lymphedema that involves what assessment?

Accepted Answer

Attempting to pinch and lift a fold of skin at the base of the second toe (or finger)

Answer

A positive Stemmer sign occurs when skin at the base of the second digit cannot be lifted into a fold due to subcutaneous fibrotic changes, indicating lymphedema.

Accepted Answer

Breast cancer

Answer

Breast cancer treatment, particularly axillary lymph node dissection and radiation, is the most common cause of secondary lymphedema in the United States.

Question 4

What is the estimated lifetime risk of lymphedema for breast cancer survivors who undergo axillary lymph node dissection (ALND)?

Accepted Answer

20–40%

Answer

Studies report approximately 20–40% of breast cancer survivors who undergo ALND will develop lymphedema, with risk increasing when radiation is added.
