The CT scan confirmed the local extension, demonstrating the absence of distant or nodal metastasis, while a solid lesion of the right ureter close to the right iliac cross, suggestive for urotelial neoplasm was incidentally founded (Fig. 2).
Squamous epithelial cells in the context of glandular mucosa infiltrating the submucosa. The simple tubular glands show superficial hyperkeratinization. Evidence of extensive infiltration of lympho-monocytic cells in the submucosa (hematoxylin-eosin x20).
