When population of mast cell accumulates in 1 tissue (eg skin, bone marrow, liver, GI, lymph node, spleen)
When mast cell is activated, it releases heparin and histamine into surrounding skin, causing inflammation that causes blood vessels to leak (resulting in localized itch, swelling,redness and at times blistering (this is a normal response in insect bites - mosquito triggers mast cell activation)

It’s a circulation problem (venous insufficiency), not a lesion. Not healing and pain due to edema or venous insufficiency or LipoDermatoSclerosis (fibrotic change in skin and subQ fat due to Venous insufficiency) (so see vascular surgeon to eval)
Tx: lymphedema clinic, vascular surgeon (Dr. D’Souza), hose and elevation
RTC 4-8 wks, add wound care and AQUAPHOR BID to soften scab if not healing
+ TRENTAL 400 TIC (Pentoxifylline): any h/o of bleeding or ulcers? Not a blood thinner, increases RBC flexibility and stimulates finrinolysis.

How to explain to pt upset that lesion wasn’t picked up 1 month ago during regular skin check
It looked like an SK (inflamm. Papule or lichenoid keratosis) and it’s not standard of care to bx a benign looking lesion (portal for infection). TOday the top has been scraped and irritated and can’t tell if there is a malignant process involved (papules can change). An iSK can’t be differentiated from SCC clinically. GUarantee that we look at all suspicious lesions carefulully with dermatoscope. At that time, it looked benign but today, it’s hard to tell what’s underneath - could still be just an irritated SK due to scratching so best to bx today
A month ago could have been a smaller SK and they can grow, causing irritation and itch.

- (the med that make RBCs more flexible TRENTAL (rental)
217
