Firm, ulcerated nodule with peripheral scale on the arm

A 46-year-old previously healthy woman originally presented to the dermatology clinic for a full skin examination and was incidentally noted to have a nodule on her right arm. The patient stated that the lesion had been present for several months and began as a small pink papule that had been slowly increasing in size. She denied any itching, tenderness, pain, or bleeding. The physical examination revealed a 1.0-cm firm, ulcerated pink nodule with peripheral scale on the right proximal arm (Fig 1).
