Carcinoma of the stomach in childhood is exceedingly rare. We now report on a case of carcinoma of the stomach in a 7-year-old Japanese boy, the youngest with so-called adult-type carcinoma of the stomach in Japan. The tumour was located mainly in the cardial region. Total gastrectomy was performed and an oesophago-jejunostomy was constructed. Histological studies revealed an anaplastic adeno-carcinoma. The possibility of gastric malignancy should always be considered when gastro-intestinal symptoms persist, even in children.
In Japan, the results of histopathologic analyses on esophageal carcinomas have shown that almost all of them are squamous epithelial cancers. The abnormal epithelium that is difficult to differentiate by endoscopy can be easily visualized by chromoendoscopy with the use of iodine staining. Since the establishment of endoscopic mucosal resection (EMR), it has been used increasingly to treat mucosal cancers. It is necessary to diagnose accurately the depth of invasion of mucosal cancer when it is to be treated by EMR. In this article, we explain our routine techniques to visualize and interpret the lesions that are candidates for EMR. It is of great benefit to detect lesions at their early stage, which leads to the most desirable endoscopic treatment.
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.
