case_images: Cytospins [Figure 1a-b] and cell block [Figure 1c] were hypercellular, with numerous large, single and pleomorphic cells with an epithelioid appearance, eccentrically located and convoluted nuclei. Immunohistochemical studies performed on the cell block showed positivity of the malignant cells with vimentin, epithelial membrane antigen [EMA, Figure 1d], desmin [cytoplasmic, Figure 1e] and cytokeratin AE1/AE3.
