ABSTRACT
Clinical evaluation, upper gastrointestinal endoscopy and electron microscopy of mucosal biopsies from antrum, body and fundus of stomach were performed in three control subjects and 17 habitual tobacco chewers. Electron microscopic abnormalities such as discontinuous, fragmented basement membrane with reduction in hemidesmosomes, and widened intercellular spaces filled with clusters of desmosomes were found in the gastric mucosa of habitual tobacco chewers; these were similar to those reported in experimental carcinogenesis and leukoplakia. It is concluded that habitual chewing of tobacco produces electron microscopic alterations in the human gastric mucosa which may be important precursors for gastric malignancy.
