We report the case of a 66-year-old white man with a 6-month history of a blue-gray plaque of the glans. The patient was heterosexual, with 2 sexual partners in the last 6 months, and denied condom use. There was no personal or family history of melanoma. Physical examination of the uncircumcised penis found a round, well-demarcated, smooth, blue-gray plaque measuring 83 10 mm, arising within an erythematous background plaque of the glans (Fig 1). The remaining physical examination was unremarkable, including the oral cavity.
