A man in his 80s presented with a 2-year history of an asymptomatic, expanding eruption on the trunk and extremities. He denied any systemic symptoms. Physical examination revealed a serpiginous, erythematous eruption with a peripheral scale resembling wood grain (Figure). Histologic findings showed a perivascular lymphohistiocytic infiltrate with no deposition noted on a direct immunofluorescence assay. A workup for malignancy revealed a mass in the prostate with bilateral para-aortic and inguinal lymphadenopathy and an elevated level of prostate-specific antigen. The patient declined surgery and was lost to follow-up.
