Previous immunof luorescent studies (1) revealed that the gastric mucosaspecif is epithelial glycoprotein distributed in mucoid cells and secreted mucus in the normal gastric mucosa as well as even in the diffusely and invasively proliferated gastric cancer cells in the mucosal, submucosal and muscular layer.Krukenberg tumor, which metastasizes frequently not only to the ovary but also to other various organs, is generally characterized by mucin-producing epithelial cells having a signet ring form. Its primary tumor is recognized to be most often in the gastrointestinal tract (2-5).The present investigation dealt with the immunofluorescent staining of such cancer cells which metastasized to different organs apart from the primary gastric lesion.
