case_images: Microscopically, the tumour consisted of elongated, anastomosing tubules separated by lakes of mucin from a prominent spindle cell area. The tubules were composed of low cuboidal cells with an amphophilic to eosinophilic cytoplasm with low-grade nuclei. Foci of sarcomatoid differentiation were seen with pleomorphic high-grade nuclei without any evidence of vascular invasion. Haematoxylin and eosin, 10x.
