Q. A 30-year-old patient presents with a prominent, raised scar on the shoulder, which has been gradually enlarging over the past year. The scar developed following a minor surgical procedure. The patient reports the scar is sometimes itchy and painful, and expresses concern about its appearance. There is no history of similar lesions elsewhere on the body. On physical examination, there is a firm, rubbery, and raised scar extending beyond the original wound margins, measuring approximately 5 cm in diameter. The scar has a shiny surface and is reddish-purple in color. What is the most appropriate initial treatment for this patient?
