Beyond Helicobacter pylori: gastric T-cell lymphoma as an unusual cause of gastrointestinal bleeding.

<title>Abstract</title> Primary gastric T-cell lymphoma is a rare and aggressive neoplasm with nonspecific clinical presentation. We report the case of a 75-year-old patient who presented with upper gastrointestinal bleeding secondary to a gastric mass, with histological analysis confirming a high-grade T-cell lymphoma. This case highlights the importance of considering this entity in the differential diagnosis of hemorrhagic gastric lesions.
