a H&E; Patient's primary esophageal mass-invasive moderately to poorly differentiated adenocarcinoma (x100). Note the dysplastic glands underlying the squamous epithelium. b H&E; High power view of primary esophageal mass (x400). Note the enlarged, hyperchromatic nuclei with frequent mitoses and necrosis. c H&E; Spinal intradural tumor-metastatic poorly differentiated adenocarcinoma (x100). d H&E; High power view of spinal tumor (x400). Note the similar cytological features-enlarged, hyperchromatic nuclei, increased mitoses and necrosis, to the esophageal primary
