[Endoscopic and histologic findings in malignant non-Hodgkin lymphomas of the stomach]

The authors have carried out a retrospective analysis of primary malignant Non-Hodgkin-lymphomas of the stomach verified histologically by surgical specimens, with the patients being submitted preoperatively to a gastroscopy with biopsy. The endoscopic and histological findings are outlined. Endoscopically the diagnosis of a malignant lymphoma was established only once, while an ulcerated carcinoma was diagnosed in almost two-thirds of the cases. The histological diagnosis of a malignant lymphoma was established in 10 cases, and a malignant lymphoma suspected in 6 cases. A carcinoma was diagnosed in 4 patients. The results are compared with the literature data and diagnostic problems discussed.
