A routine visit

A 40-year-old male presents to the office for a routine visit. When

questioned by the NP about any changes in skin lesions the patient reports he has a lot of “moles” but the one on his back is itchy at times and feels like it’s raised. He reports working in construction but using sunscreen regularly. On examination, there is a 0.5 cm lesion that is raised, shiny, flesh-colored, with pearly borders on the neck above the shirt collar.
Discuss the differential diagnosis, diagnostics, and treatment plan.
