Cutaneous syncytial myoepithelioma: (a) this variant of myoepithelioma occurs predominantly in the superficial dermis (×25); (b) epithelioid and plasmacytoid cells are arranged in sheets with little or no intervening stroma (×200); (c) AE1/AE3 immunohistochemistry is most often negative or stains only scattered isolated cells (×100); (d) PS100 (×100) and (e) EMA immunohistochemistry stains various populations of cells (×100); (f) fluorescence in situ hybridization (FISH, break-apart) demonstrates clonal rearrangement of EWSR1 gene (×1000).
