World J Clin Cases. Grading scheme is based on the proliferative rate (mitoses and Ki67 index) as follows: Low grade or grade 1 (G1): mitoses 2/2 mm, Intermediate grade or grade 2 (G2): mitoses 2 - 20/2 mm, High grade or grade 3 (G3): mitoses > 20/2 mm, Mitotic count should be evaluated in a 2 mm, Ki67 index should be estimated in 500 cells in the hotspot regions (, If there is any discrepancy between mitotic index and Ki67 index, the higher should be considered for the classification (. //--> Clipboard, Search History, and several other advanced features are temporarily unavailable. SCLC and LCNEC are high-grade malignant tumors, AC is intermediate-grade, and TC is considered low-grade . Our case reports present clinical scenarios that may be encountered in practice, focusing on clinical and histopathological features of different types of g-NENs with their specific management. We wish to highlight the unusual occurrence of gastric neuroendocrine cell hyperplasia and type I neuroendocrine tumours within three hyperplastic polyps. MeSH These NENs precursor endocrine cells may vary from 1 site to the other, depending on the functional necessities of each site. The proliferative index Ki-67 was <2%. In our case series we presented different clinical scenarios that may be encountered in practice regarding gastric NENs. [25,27] Tumors are classified as G1 NETs, with proliferation marker (Ki-67 index) less than 2%. Gastrointestinal Pathology and Its Clinical Implications 2nd ed2014;190225.

[16], Some research focused on risk related to ECL cells changes, but it is difficult to define which type of proliferation has the greatest potential for neoplastic transformation. It is unclear whether the two pathologies occurred simultaneously or independently. A 61-year-old male with a history of peptic ulcer disease underwent upper gastrointestinal endoscopy for heartburn, abdominal pain, diarrhea, and mild iron deficiency anemia (hemoglobin = 11.82 g/dL). [24] The diagnostic work-up should comprise a screening for possible associated parathyroid and pituitary tumors, as well as the assessment of parathyroid hormone level, ionized calcium, and plasma prolactin. [19], Although ECL cells are not readily recognized on routine hematoxylin and eosin staining, they contain vesicular granules highlighted with immunohistochemical staining. [29]. Dis Colon Rectum.

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 Their morphology, histogenesis, and natural history.
