case_images: (a)-(d) Haematoxylin and eosin stained slides of tumour showing carcinomatous epithelial islands within sarcomatous elements ((a) 400x). Sarcomatous spindled cells with pleomorphic nuclei ((b) H&E, 400x). Immunohistochemistry: vimentin IHC showing diffuse positivity of spindled sarcoma cells ((c) 200x). Pan-cytokeratin IHC showing positivity of epithelial carcinoma cells ((d) 400x).

case_images: Hyaline globules, bone, or cartilage elements were looked for in tumor areas but were not demonstrable (Figures 1(a) and 1(b)). Immunohistochemically, cytokeratin decorated the neoplastic epithelial cell nests and mesenchymal spindled tumour cells were observed to be vimentin positive, with sharp areas of demarcation. (Figures 1(c) and 1(d)).
