The goblet cell carcinoid (GCC) is a rare biphasic gastrointestinal tract tumour that consists of a neuroendocrine component and a conventional carcinoma, histologically arising from Paneth cells. [1]
A carcinoid (also carcinoid tumor) is a slow-growing [1] type of neuroendocrine tumor originating in the cells of the neuroendocrine system. In some cases, metastasis may occur. Carcinoid tumors of the midgut ( jejunum , ileum , appendix , and cecum ) are associated with carcinoid syndrome .
Goblet cells are simple columnar epithelial cells, having a height of four times that of their width. The cytoplasm of goblet cells tends to be displaced toward the basal end of the cell body by the large mucin granules, which accumulate near the apical surface of the cell along the Golgi apparatus, which lies between the granules and the nucleus.
appendix, [19] including well differentiated NETs (benign); well differentiated NETs (uncertain malignant potential); well differentiated neuroendocrine carcinoma (with low malignant potential); mixed exocrine-neuroendocrine carcinoma (goblet cell carcinoma, also called adenocarcinoid and mucous adenocarcinoid) Hindgut GEP-NET [20] [21]
The two main types of hyperplastic polyps are microvesicular mucin-rich type and goblet cell-rich type. [1] A mucin-poor type with eosinophilic cytoplasm, which is rare, was previously described. [4] However, the mucin poor type is no longer considered a distinct subtype. [1]
Barrett's esophagus - Wikipedia
A microscopic view of stomach lining containing goblet cells, parietal cells, chief cells, and enteroendocrine cells. [ 9 ] Unfortunately, the early anatomical changes in the lining of the stomach that lead to cancer are rarely noticeable.
It is characterized by the appearance of goblet cells and expression of intestinal cell markers such as the transcription factor, CDX2. Although H. pylori infection can cause gastrointestinal metaplasia, its eradication does not reverse the process. [1]
