A case of primary isolated non-Hodgkin's lymphoma of the esophagus in an immunocompetent patient.

Primary non-Hodgkin's lymphoma of the esophagus is a rare disease. A case of primary isolated non-Hodgkin's lymphoma of the esophagus in a 77-year-old man without acquired immunodeficiency syndrome is presented. We describe the clinical features and the imaging findings (barium swallow, endoscopic ultrasonography and CT) of a biopsy proven B-cell lymphoma with diffuse transmural involvement of the esophagus wall, which was discovered incidentally. We also briefly review the literature.
