Small intestine: the intestinal epithelium is focally moderately thickened by a cauliflower-like 3 mm in diameter mass. This mass is composed of glands lined by a one cell-thick columnar epithelium supported by a small amount of fibrovascular stroma. Neoplastic cells are columnar, with indistinct cell borders and a moderate amount of amphophilic cytoplasm. Neoplastic cells do not contain mucin droplets. Mitoses are numerous. There is no evidence of invasion in the stroma or in the submucosa. |
