Snapshot A 50-year-old Caucasian man presents to his dermatologist for a scar that is hindering mobility in his right knee. A few weeks ago, he tripped and fell on a sharp rock, resulting in a 6 cm cut over his knee. Since then, his cut has healed and a raised pink scar has grown over the wound. On physical exam, it is exactly 6 cm without growing beyond the original wound and is pink and shiny. His right knee does not fully extend due to the scar. To prevent further contractures, the physician discuss the possibility of surgical excision.
