Abstract

Gastric carcinoid is a rare type of gastric malignancy accounting for around 7% of all gastrointestinal neuroendocrine tumours (NETs). While most gastric NETs (gNETs) are readily visible through direct visualisation by upper endoscopy, around 25% of gastric carcinoids are invisible because they are located in the submucosal gastric regions of the body and fundus. gNETs located in the intra-mucosal areas can be identified by gastric mapping; this can be done by taking random gastric biopsies from the antrum, body and fundus. We report a case of a well-differentiated gastric NET type 1 with atrophic gastritis diagnosed on upper endoscopy and pathological immunohistochemistry staining.

Learning points: The case highlights that not all gNETs are visible under direct endoscopic visualisation.It is essential to understand the different types of gNETs.Understand that both type and size of gNETs impact therapeutic implications and prognosis.

调查 B12 缺乏症，偶然诊断出胃癌类癌。

胃类癌是一种罕见的胃恶性肿瘤，约占所有胃肠道神经内分泌肿瘤（NET）的7%。大多数胃癌网（gNET）可通过上内镜直接观察到，但约有25%的胃类癌是看不见的，因为它们位于胃体和胃底的粘膜下区域。位于粘膜内区域的胃癌网可通过胃映射来识别；这可通过从胃窦、胃体和胃底随机取胃活检来实现。我们报告了一例经上内镜检查和病理免疫组化染色确诊的伴有萎缩性胃炎的分化良好的 1 型胃 NET 病例：本病例强调了并非所有 gNET 都能在内镜直视下看到。了解 gNET 的不同类型至关重要。

期刊介绍： The European Journal of Case Reports in Internal Medicine is an official journal of the European Federation of Internal Medicine (EFIM), representing 35 national societies from 33 European countries. The Journal''s mission is to promote the best medical practice and innovation in the field of acute and general medicine. It also provides a forum for internal medicine doctors where they can share new approaches with the aim of improving diagnostic and clinical skills in this field. EJCRIM welcomes high-quality case reports describing unusual or complex cases that an internist may encounter in everyday practice. The cases should either demonstrate the appropriateness of a diagnostic/therapeutic approach, describe a new procedure or maneuver, or show unusual manifestations of a disease or unexpected reactions. The Journal only accepts and publishes those case reports whose learning points provide new insight and/or contribute to advancing medical knowledge both in terms of diagnostics and therapeutic approaches. Case reports of medical errors, therefore, are also welcome as long as they provide innovative measures on how to prevent them in the current practice (Instructive Errors). The Journal may also consider brief and reasoned reports on issues relevant to the practice of Internal Medicine, as well as Abstracts submitted to the scientific meetings of acknowledged medical societies.
