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 .
Barrett's esophagus is a condition in which there is an abnormal (metaplastic) change in the mucosal cells lining the lower portion of the esophagus, from stratified squamous epithelium to simple columnar epithelium with interspersed goblet cells that are normally present only in the small intestine and large intestine.
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.
Metastases to the liver can be treated by several types of hepatic artery treatments based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70–80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the ...
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 ]
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]
Goblet cell-rich type: Elongated, fat crypts and little to no serration. Filled with goblet cells, extending to surface, which commonly has a tufted appearance. [11] Tubular adenoma: 2% at 1.5 cm [12] Low to high grade dysplasia [13] Over 75% of volume has tubular appearance. [14] Tubulovillous adenoma: 20% to 25% [15] 25–75% villous [14 ...
