Keloids

The goal of this clinical trial is to learn how well intralesional 5 fluorouracil with cryotherapy works to treat keloids as compared to intralesional 5 fluorouracil alone on keloids. It will also learn about the safety of both these treatments. The main questions it aims to answer are: * What well does cryotherapy followed by intralesional 5 fluorouracil (5FU) work to treat keloids as compared to 5 fluorouracil (5FU) alone? * What is participant's satisfaction when treated with cryotherapy followed by intralesional 5 fluorouracil (5FU) as compared to 5 fluorouracil (5FU) alone? * What skin problems do participants have when treated with cryotherapy followed by intralesional 5 fluorouracil (5FU) and 5 fluorouracil (5FU) alone? Researchers will compare cryotherapy followed by intralesional 5 fluorouracil (5FU) with 5 fluorouracil (5FU) alone to see how well both work. Participants will be divided into two groups: For Group A: Cryotherapy will be done at lesion site followed by intralesional 5FU every 3 weekly. For Group B: Intralesional 5FU will be given at lesion site every 3 weekly. Keloids will be assessed at the start of trial and then after 12 weeks of treatment.

Keloids are non-cancerous (benign) growths on the skin. They form after an injury, when the skin makes too much connective tissue that thickens and hardens. These keloids cause big problems for people. They grow uncontrollably on their own, itch, hurt, and look bad. This is especially true if they're on visible areas like the head or neck-they harm both a person's physical comfort and mental well-being. 32P application is a popular treatment for keloids. It's simple, easy to use, quick, and doesn't have many limits on where or when it can be used. Besides keloids, it also works for surface skin issues like hemangiomas. Here's how 32P works: When it breaks down (decays), it releases beta rays. These rays create a local effect that changes the shape and function of the affected tissue. Blood vessel cells in the area swell, get inflamed, and shrink, eventually blocking the blood vessels. Beta rays also stop two key things from growing too much: fibroblasts (cells that make connective tissue) and new blood vessels. This is how the treatment works-with very low chances of the keloid coming back and few side effects. For these reasons, we think combining surgery with 32P application is an effective way to treat keloids. Its success rate is similar to, or even better than, surgery combined with low-dose radiation. Also, two factors matter a lot for how well the treatment works long-term: when 32P application is started, and the dose used.
