Histologic examination revealed a large, symmetric neoplasm consisting of digitated epidermal hyperplasia with hypergranulosis (Figure 2). In the dermis, there were collections of small epithelial cells with uniform nuclei and scant cytoplasm, in which there were occasional small ductal and tubular structures (Figure 3). There were prominent anastomoses between the epithelial collections of cells and the epidermis. The stroma was vascular and slightly edematous. The lesion was fully excised, with no recurrence noted after 2 years.
