title: Intermediate lymphocytic lymphoma massively involving the gastrointestinal tract.
abstract: A case is presented of intermediate lymphocytic lymphoma seen in a 53 year old male, which extensively infiltrated systemic organs, including the entire digestive tract from the esophagus to the rectum. Peyer's patch invasion was evident. Multiple intestinal perforations caused death 5 months later. Surface marker studies suggested the marginal zone origin for this CD20+ B cell malignancy.
