Early gastric mixed neuroendocrine‐non‐neuroendocrine neoplasm with early poor prognosis after endoscopic submucosal dissection: A case report [PDF]

DEN Open, 2022
Early gastric mixed neuroendocrine‐non‐neuroendocrine neoplasms (MiNENs) are rare diseases, with no data on their incidence and prognosis. We report the case of intramucosal gastric MiNENs for endoscopic submucosal dissection (ESD) treatment.

Gastric mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) with pancreatic acinar differentiation: a case report [PDF]

Diagnostic Pathology, 2019
Background Gastric mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) are infrequently encountered in routine practice. Some gastric neuroendocrine carcinomas (NECs) have a variety of differentiation patterns; however, pancreatic acinar ...

Case report: A challenging case of stage IVB mixed neuroendocrine-non-neuroendocrine neoplasm of the gallbladder treated with extended radical resection including portal vein reconstruction [PDF]

Frontiers in Oncology
BackgroundGallbladder cancer is a highly lethal biliary tract malignancy. Among them, mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN), particularly those containing large cell neuroendocrine carcinoma (LCNEC) components, are extremely rare and ...

Mixed Neuroendocrine Non-Neuroendocrine Neoplasm of the Ampulla of Vater: Report of a Rare Location [PDF]

Ochsner Journal
Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) are rare tumors of the gastrointestinal tract with neuroendocrine and non-neuroendocrine components. Ampullary MiNENs are extremely rare, with few cases reported to date.A 41-year-old male was diagnosed incidentally with a dilated common bile duct and intrahepatic biliary radicles while being ...

Mixed Neuroendocrine-Non-Neuroendocrine Neoplasms of the Rectum: A Case Report

Case Reports in Oncology
Introduction: Mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN) represent roughly 1–2% of all colorectal malignancies. Given the rareness and heterogeneity of these mixed tumors, recognition and accurate diagnosis remain a challenge.

Do neuroendocrine carcinomas and mixed neuroendocrine–non-neuroendocrine neoplasm of the gastrointestinal tract have the same prognosis? A database analysis of 12,878 cases [PDF]

Therapeutic Advances in Endocrinology and Metabolism, 2020
Background: Neuroendocrine carcinomas (NECs) and mixed neuroendocrine–non-neuroendocrine neoplasm (MiNEN) in the gastrointestinal (GI) tract are both rare and malignant; however, it is unclear whether their prognosis is the same.

Retrospective study on mixed neuroendocrine non-neuroendocrine neoplasms from five European centres [PDF]

World Journal of Gastroenterology, 2019
Mixed neuroendocrine non-neuroendocrine neoplasm (MiNEN) is a rare diagnosis, mainly encountered in the gastro-entero-pancreatic tract. There is limited knowledge of its epidemiology, prognosis and biology, and the best management for affected patients is still to be defined.To investigate clinical-pathological characteristics, treatment modalities and

When Immunophenotype Is Not Identity: A Clinicopathological Review of Neuroendocrine Differentiation in Tumors of the Female Genital Tract [PDF]

Diagnostics
Neuroendocrine differentiation in tumors of the female genital tract is an uncommon but diagnostically consequential finding. Its interpretation is challenging because neuroendocrine marker expression does not necessarily define a neuroendocrine neoplasm.
