Laparoscopic resection of signet ring cell gastric cancer resembling infiltrating subepithelial tumor

OpenAlex İngilizce

To the Editor, Gastric cancers exhibit different gross appearances, ranging from well-defined protuberant to diffuse infiltrating tumors (1). Multiple biopsies, usually 6 or more, are required to minimize the false-negative rate. However, endoscopy alone does not allow sufficient histopathologic diagnosis of submucosal tumors of the stomach. We present a case of signet ring cell gastric cancer that was not obtained by histopathological diagnosis by multiple endoscopic biopsies.
