Signet ring cell carcinoma is a specific histological subtype of gastric adenocarcinoma. The tumor name is due to the characteristic type of malignant cells nuclei, that take the form of a ring. Such cells contain a large amount of intracellular mucin, which shifts the nucleus to the periphery creating a typical microscopic appearance. Currently, there is no single point of view, regarding the treatment strategy of such patients, as well as the prognosis of the disease. Modern endoscopic technologies allow not only to detect signet ring cell carcinoma of the stomach at an early stage, but can also be the method of choice in the radical treatment of such patients. This clinical observation aims to demonstrate the results of endoscopic diagnosis of early signet ring cell carcinoma in two patients with different treatment approaches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
