Non-Hodgkin malignant lymphoma of gastrointestinal tract detected by ultrasonography

Introduction: The gastrointestinal tract is the most frequent location for primary extra-nodal non-Hodgkin lymphomas. Primary NHLs located in the gastrointestinal tract account for only 1–4% of gastrointestinal malignancies. The complaints are very varied and often atypical depending on the different locations, which makes the diagnosis difficult.
