case_images: The smears were moderate-to-highly cellular in a hemorrhagic background with small basaloid cells in cohesive clusters or as pseudopapillary projections with focal peripheral palisading [Figure 1].

case_images: Foci of loosely arranged, spindle-shaped cells with ovoid nuclei mimicking stellate reticulum-like cells were also seen [Figure 2].

case_images: Out of the four smears, one showed squamous epithelial cells with abundant cytoplasm and central nucleus adjacent to the cluster of basaloid cells [Figure 3].
