Can You Identify This Lesion Seen in a Patient With Melanoma?

As Mr. V., a 52-year-old male, was getting his hair cut, his barber noticed a dark bump in an area on the side of his scalp, where the hair was thinning. At Mr. V.’s next haircut, his barber indicated that the area was getting larger and that it looked like it had bled. Mr. V. made an appointment with his primary care doctor, who then sent Mr. V. to a dermatologist. The dermatologist biopsied the lesion, which was found to be a 2.8-mm Breslow depth nodular melanoma. Additional characteristics included positivity for angiolymphatic invasion, a positive deep margin, and 12 mitoses/mm2.
