CLT Lymphedema Pathophysiology & Staging 3

Question 1

Cellulitis in a lymphedematous limb is dangerous primarily because:

Accepted Answer

It causes permanent lymph node damage and worsens lymphedema

Answer

Repeated episodes of cellulitis further damage lymphatic vessels and nodes, progressively worsening lymphatic transport capacity and lymphedema severity.

Question 2

The protein-to-fluid ratio in lymphedema exudate compared to venous edema is:

Accepted Answer

Higher in lymphedema

Answer

Lymphedema fluid has a high protein concentration (>1.5 g/dL) compared to low-protein venous edema fluid, which is a key diagnostic distinction.

Question 3

Which condition is a known risk factor for developing breast cancer-related lymphedema (BCRL)?

Accepted Answer

Number of lymph nodes removed during surgery

Answer

The number of axillary lymph nodes removed is the strongest predictor of BCRL risk, with axillary lymph node dissection (ALND) carrying much higher risk than sentinel node biopsy.

Question 4

Lipolymphedema differs from classic lymphedema in that it involves:

Accepted Answer

Abnormal fatty tissue deposits combined with lymphatic dysfunction

Answer

Lipolymphedema involves abnormal subcutaneous fat deposition (lipedema) combined with secondary lymphatic insufficiency due to increased tissue volume.

Question 5

In the context of lymphedema, 'fibrosis' is best described as:

Accepted Answer

Replacement of soft tissue with dense collagen due to chronic protein accumulation

Answer

Lymphedema fibrosis is the progressive replacement of normal soft tissue with dense collagen matrix, driven by chronic protein-rich fluid and inflammatory mediators.
