case_images: The outer surface was irregular with a fungating mass (8 x 4.5 x 4 cm) infiltrating the underlying soft tissue (Figure 1(a)). The cut surface was solid, heterogeneous with firm white as well as soft, necrotic, and hemorrhagic areas (Figure 1(b)).
case_images: Histology sections using hematoxylin and eosin staining. (a) Tumor cells interconnecting to epidermis. (b) Luminal spaces and cuticles (black arrow). (c) Brisk mitotic figures (black arrow). (d) Lymphatic invasion. (e) Positive lymph node. (f) Epithelial membrane antigen (EMA) positivity in rim of ductules (black arrow).

case_images: fig2-2050313X241256868
case_images: Histopathological examination shows broad, anastomosing cords, solid columns, and nests of polygonal basaloid cells with hyperchromatic nuclei, prominent nucleoli, and mitotic figures, with spread from the epidermis into the papillary and reticular dermis (Figure 2(a)-(c)). Lymphovascular invasion was also noted (Figure 2(d)). The lymph node was positive for tumor cells (Figure 2(e)).
