[33], The patient with antral tumor and liver metastases (case 3) declined surgical treatment and chose the medical therapy. Neuroendocrine tumors of the gastrointestinal tract. Given concern for type 1 GNET, she underwent a gallium-68 DOTATATE positron emission tomography scan, which was negative. In the head of the pancreas, a small nodule, well-demarcated, grey tan, of 25 mm in size, was identified. [46]. Epub 2014 Aug 22. The cytomorphology of carcinoid tumor (low-grade neuroendocrine carcinoma) is similar to that of the tumor at different sites. [27]. Neuroendocrinology. Malignancies of the stomach and esophagus remain devastating for the patient and challenging for the treating physician. Endoscopic polypectomy of the largest tumor (10 mm diameter) was performed, and targeted biopsies from the other polypoid lesions and from the surrounding mucosa were obtained, including distinct fragments from the antrum and corpus. [53,54] As concern the gastric tumor, there have been reported few cases of prostate adenocarcinoma metastatic to the stomach. 2018;89(8-S):1003. MIB1 immunohistochemical stain showed a Ki-67 proliferation index of less than 3% within these aggregates, which was pathologically suggestive of a type 1 microneuroendocrine tumor (Figure 2). The histological diagnosis and tumor grading according to standard terminology is important in estimating tumor behavior and in adopting the best therapeutic decision. Intern Med.

Printed from Surgical Pathology Criteria: WHO 2010 has changed back to neuroendocrine cell from endocrine cell for these lesions, Endocrine cell hyperplasia and neoplasia are equivalent terms to those used below, Gastric carcinoids and neuroendocrine cell proliferations arise in three settings, Hyperplasia, dysplasia and neoplasia are not uncommon, Most carcinoids are <1 cm and are not aggressive, May not progress even if not resected, Without MEN1, generally only neuroendocrine cell hyperplasia is seen, With MEN1, may have neuroendocrine cell dysplasia and neoplasia, Such carcinoids may behave aggressively, Over half may invade deeply and metastasize, Types of neuroendocrine cell proliferations, Chromogranin and/or synaptophysin stains are necessary for evaluation of neuroendocrine cells, Scattered individually, primarily in the basal crypt epithelium, Linear or micronodular clusters of at least 5 cells, Micronodular clusters 150 microns in greatest dimension, At least 2 linear chains / mm or 1 micronodule / mm, Enlargement and fusion of five or more micronodules, >150 microns in greatest dimension, Microinfiltration of lamina propria, Nodule with formation of new stroma, Nodules 0.5 mm to 0.5 cm have been termed microcarcinoids, Gastric endocrine cell proliferations typically show features seen in other GI tract well differentiated endocrine proliferations, Occasional reports of scattered larger atypical nuclei, Trabecular, acinar, pseudo glandular architecture, Variable positivity for neuroendocrine markers, It has been proposed that type A and B hyperplasia and dysplasia may progress to carcinoid (Berna 2008, Annibale 2001), This is not universally accepted for hyperplastic lesions (Solicia 1995), It would appear that both merit followup, The behavior of carcinoids is dependent upon size, proliferation rate and the setting in which it arises (see, Well differentiated processes including carcinoids, Duodenum NOS and proximal jejunum, Ileum and distal jejunum WHO International Histological Classification of Tumours 2nd edBerlin: Springer; 2000.

The classic carcinoid syndrome consisting in cutaneous flushing, tachycardia and secretory diarrhea rarely occurs, but is observed most frequently in patients with liver metastases. [2830] The possibility of vascular invasion and metastases endorses the role of endoscopic ultrasonography in the assessment of the depth of tumoral invasion and lymph nodes involvement, especially in tumors greater than 10 to 20 mm in size.
