A CASE OF MULTIPLE LYMPHOMATOUS POLYPOSIS (MLP) OF THE GASTROINTESTINAL TRACT: IS MLP A DISTINCT ENTITY?

Abstract

A 67-year-old woman was admitted to our hospital because of edema in the lower extremities in June, 1990. Cervical lymphadenopathy and marked lymphocytosis (leukocyte count of 20, 600/μl with 76.5% lymphoid cells) were noted. Endoscopic and radiologic examinations disclosed giant folds in the stomach, a cauliflower-like tumor in the ileocecal valve, and numerous polypoid lesions in the stomach, duodenum and entire ileum. The patient was diagnosed as having intermediate lymhoytic lymphoma with features of multiple lymphomatous polyposis of the gastrointestinal tract (MLP) on the basis of histologic and immunohistochemical examinations. The authors discussed by reviewing the literature whether MLP was a distinct clinicopathological entity or not.
