Light microscopic examination of the biopsy specimen revealed irregular epidermal hyperplasia associated with a dermal proliferation consisting ofaggregates of cells demonstrating a predominantly lobular growth pattern The constituent round and polyhedral cells were monotonous, with abundant eosinophilicgranular cytoplasm and distinct cell borders. Some cells demonstrated pustulo-ovoid bodies of Milian in the cytoplasm (Figure3). The nuclei were typically centrally placed, small, and often slightly hyperchromatic with inconspicuous nucleoli. Mitotic figures wereabsent.
