A Case Report: Gastric Mixed Neuroendocrine-Nonneuroendocrine Neoplasm with Aggressive Neuroendocrine Component
Mixed neuroendocrine-nonneuroendocrine neoplasm (MiNEN) is defined as mixed epithelial neoplasms composed of both neuroendocrine and nonneuroendocrine components with variable proportions for each component. Neuroendocrine component can show morphological features including well- or poorly differentiated neuroendocrine neoplasms and nonneuroendocrine component can present different tumor types ...
متن کاملMixed Acinar-Neuroendocrine Carcinoma of the Pancreas with Neuroendocrine Predominance
Background. Pancreatic tumors are rare and could arise from either the exocrine (ductal and acinar cells) or the endocrine (neuroendocrine cells) components of the pancreas. In some instances, the occurrence of pancreatic tumors comprising both acinar cells and neuroendocrine cells, with neuroendocrine cells making up more than 30% of the tumor, has been identified. This unique entity has been ...
متن کاملNeuroendocrine liver metastasis in gastric mixed adenoneuroendocrine carcinoma with trilineage cell differentiation: a case report.
Mixed adenoneuroendocrine carcinoma (MANEC) is a rare disease, which mostly occurs in the gastrointestinal tract and pancreas. Here we report a case of gastric MANEC with tri-lineage differentiation in which only the neuroendocrine component had metastasized to the liver. Liver and gastric masses were detected by abdominal computed tomography, and the preoperative relationship between liver and...

متن کاملPedunculated gastric neuroendocrine tumor: a case report
Background and study aims: Gastric neuroendocrine tumors (NETs) are rare lesions that develop from neuroendocrine cells. NETs are classified into 3 types based on the rate of mitosis and Ki-67 labeling index; the NET G1 type is synonymously referred to as carcinoid. Gastric NETs are usually discovered as submucosal tumors during upper gastrointestinal endoscopic examination. This study reports ...
