A Case of Gastric MiNEN Arising from the Heterotopic Gastric Glands. Intern Med. 2020 Aug 22;: Authors: Tanaka Y, Tokubayashi Y, Fujii S, Kusaka T, Shibuya S, Kokuryu H Abstract An 80-year-old woman presented with a 30-mm protruding lesion-like submucosal tumor with a central depression located at the anterior wall of the upper gastric body. The depressed area had a well-demarcated margin, while the other area was covered by a non-neoplastic mucosa. A biopsy specimen revealed neuroendocrine carcinoma. Endoscopic ultrasonography revealed a heterogeneous mass with a clearly distinguished border in the submucosal layer. The mass had two distinct areas adjacent to each other. In addition, a hypoechoic zone was observed on the margin of the mass. Distal gastrectomy was performed. The final diagnosis was a mixed neuroendocrine-non-neuroendocrine neoplasm arising from the heterotopic gastric gland. PMID: 32830181 [PubMed - as supplied by publisher]
