title: Primary malignant lymphoma of the rectum with distant metastasis to the stomach: report of a case.
abstract: Primary extranodal malignant lymphoma frequently occurs in the gastrointestinal tract: however, it is rarely encountered in the rectum. We report herein the case of an 85-year-old man who underwent abdominoperineal resection for primary malignant lymphoma of the rectum, and 1 year later, developed hematemesis caused by gastric metastasis. To our knowledge this is the first case report of such distant metastasis developing from malignant lymphoma of the rectum.
