title: [Endoscopic semeiotics of malignant lymphoma of the stomach].
abstract: The authors analyse 7 cases from their own experience and literature data. Among the characteristic signs of malignant gastric lymphoma is multicentric growth of the neoplastic nodes which may be partly covered with the mucosa. An important sign is the presence of multiple ulcerations or erosions which may occur both on the surface of the tumor and on the mucosa of parts of the stomach which are still not affected. A polypiform, cushion-like thickening of the folds is often seen against the background of the infiltrated mucosa. The color of the mucosa is bright and rich, ranging from crimson the bluish. In growth of malignant lymphoma into the stomach from affected abdominal lymph nodes endoscopy reveals a characteristic inward depression of the wall in the zone of involvement and extension of the neoplastic tissue on the mucosa.
