A 65-year-old farmer presents with a lesion on his face. He has noticed that the lesion occasionally bleeds when he towel dries his face, and the lesion has slowly grown over time. He denies any medical problems and does not smoke. The lesion is about 1 cm by 2 cm and has an uneven border. It is slightly elevated, pink and translucent and has a few crusted areas of erosion within its borders. The lesion is located next to the base of the nose. What is the most likely diagnosis?
