ABSTRACT

Introduction: The prevalence of gastric cancer in Mexico has increased in recent years, with a predominance in men. Risk factors are alcohol, tobacco, and Helicobacter pylori infection, considered in our population as of a moderate risk. Although adenocarcinoma continues to predominate as the most frequent gastric malignancy, according to the WHO, a non-negligible percentage (7-8%) is occupied by extra-nodal non-Hodgkin's lymphoma and leiomyosarcomas. Appropriate diagnostic approach and differentiation between adenocarcinoma and lymphoma are crucial since prognosis and treatment depend on it. Case report: A 79-year-old man with asthenia, malignant hypercalcemia and an incidental gastric thickening found by tomography. Endoscopic ultrasound was performed and the diagnosis of gastric lymphoma of a diffuse variety (Ann Arbor modified II2) was established. Literature review: Endoscopic ultrasound is considered a tool for the diagnosis of gastric carcinoma in all variants, mainly where the disease is in deep layers. Conclusion: Endoscopic ultrasound is a method that leads to high diagnostic accuracy in gastric lymphoma allowing biopsies of total wall thickness for immunohistochemistry.
