Primary non-Hodgkin's lymphoma of the esophagus.

Squamous cell carcinoma and adenocarcinoma constitute the majority of malignancies of the esophagus. Although lymphoma may involve any part of the gastrointestinal tract either primarily or secondarily, esophageal involvement is rare. We describe two cases of primary esophageal non-Hodgkin's lymphoma and review the literature, with particular attention to roentgenographic studies, esophagoscopic findings, and endoscopic biopsy results.
