    An 84-year-old Filipina with no personal or known family history of skin cancer presented to the dermatology clinic with a lesion on her lower back that had been present for the past 5 years. She reported insidious growth and mild pruritus associated with the lesion over the past few months. Physical examination demonstrated a 7.5 × 4.5-cm sharply defined erythematous plaque with scattered scale and interspersed nodular areas on the woman’s medial lower back (Figures).
