@cicihi4 Thank you once again for the helpful information! I did some more research to find that Intralesional 5-Fluorouracil is "an antimetabolite that inhibits DNA synthesis in rapidly dividing cells, including those in cancers. By disrupting DNA production, it causes these cells to undergo apoptosis (programmed cell death) and necrosis (tissue death). Additionally, 5-FU can stimulate the immune system to target cancer cells. When administered intralesionally [the spaces in between], it delivers a high concentration of the drug directly to the target area while minimizing systemic exposure and potential adverse effects". This has primarily been used in dermatology for specific skin conditions, including actinic keratosis - rough, scaly patches that can be pre-cancerous.

So in getting back to your original question, I'll put this out there: Has anyone been aware of receiving Intralesional 5-Fluorouracil as treatment for skin conditions -- and, if so, what has your experience been?
