Primary non‐Hodgkin's lymphoma in the esophagus

Lymphoma is a malignant neoplasm classically involving the lymph and reticuloendothelial tissues. According to the World Health Organization classification (2000) for non‐Hodgkin's lymphoma (NHL), there are over 20 different subtypes, each with its own characteristics and behavior. Gastrointestinal lymphoma is a less common type of NHL, usually affecting the stomach, colon and small intestines. The esophagus, however, is rarely involved. Here the investigators report a case of primary NHL of the esophagus so that this may be of help to physicians in future encounters.
