title: Primary histiocytic lymphoma of the esophagus.
abstract: Squamous cell carcinoma represents the most common primary malignant lesion of the esophagus (1). The initial manifestation of lymphosarcoma infrequently occurs in the gastrointestinal tract, and in one large series, there were no lymphosarcomas presenting in the esophagus (2). In the case described below, a primary histiocytic lymphoma (large cell lymphoma) was discovered in the distal esophagus.
