Hyperpigmented nodule on a young Black man

Abstract

A 32-year-old Black man without a significant medical history presented to the emergency department with a 2-year-old nonhealing lesion that was associated with recurrent bleeding on the left portion of the postauricular region of his scalp. He had no family history of malignancy. A physical examination revealed a 2.3 × 3.1-cm2 hyperpigmented nodule associated with a brown patch with a hyperpigmented border. Clinically, there was no regional lymphadenopathy. Histopathology revealed nests and irregularly shaped strands of basaloid cells with scant cytoplasm and round, dark nuclei.
