A 4-mm skin punch biopsy was performed, and the pathology report revealed a well circumscribed dermal tumor made of irregularly shaped, differently sized nests of epithelial cells, with moderately dense inflammatory infiltrates (Figure 1).
High power: the epithelial nests are composed of basaloid cells with some peripheral palisading and lymphohistiocytic infiltrates. Neither atypia, mitosis nor refraction artifacts are present (hematoxylin-eosin staining).
