This 44-year-old man presented to a clinic with multiple dark lesions on his lower extremities. When the lesions first appeared eight months ago, they were slightly raised, pink in color, and intensely itchy, but after repeated excoriation, they have become increasingly dark. The patient reports that a biopsy was inconclusive and creams and an oral medication have not helped his condition. In addition to his leg lesions, there is some involvement of the thigh, buttocks, and penis. He denies any past medical history or other medications. What condition does this man have?
