Rationale for change
I suggest moving the cloze to "ulcerations" instead of "skin." "Skin" being the cloze seems kind of silly. What could reasonably undergo ulceration in vericose veins other than skin? However, asking what *happens* to the skin (moving the cloze to 'ulcerations') better tests understanding, as it requires the learner to specifically remember what *happens* (or, can happen) to the skin of patients with VV.

Skin ulcer depicted below:
- Chronic tissue ischemia due to venous hypertension leads to venous stasis dermatitis by way of an overactive inflammatory response; chronic release of inflammatory markers leads to an increase in vascular permeability → edema, proteolytic enzymes cause chronic ulceration
- Extravasation of RBCs into the tissues lead to iron deposition and characteristic brawny discoloration (depicted below)
