A 62-year-old African American woman with history of type 2 diabetes mellitus and psoriasis presented with a tender, pruritic, 1.5 × 1.5-cm, ulcerative nodule with peripheral hyperpigmentation and associated hyperkeratotic core on the right lateral lower extremity (Figure). The lesion had been present for approximately 2 months, and the patient could not recall any inciting event.
