Remarkable improvement of clinical status in a patient with multiple lymphomatous polyposis of the gastrointestinal tract after repetitive chemotherapy.

The effect of repeated courses of chemotherapy on gastrointestinal tumors seen in a 43 year-old male patient with multiple lymphomatous polyposis involving the entire gastrointestinal tract was presented. Numerous polypoid lesions from the stomach to the rectum were the characteristic finding in this case. The biopsied specimens from polyps either of the stomach or large intestine showed diffuse lymphocytic accumulation in the submucosa, which is consistent with multiple lymphomatous polyposis of the gastrointestinal tract. Remarkable regression of the large masses in the gastrointestinal tract was obtained by two courses of VEMP therapy, along with improvement of hypoalbuminemia and a positive CRP. Recurrence of gastrointestinal masses in the cecum and rectum was also eliminated by six courses of CHOP therapy, and a total of nine courses of CHOP therapy led to complete disappearance of masses in the gastrointestinal tract. The present case is different from the others in terms of the following viewpoints that first the ensuing large masses favorably responded to repetitive chemotherapy, secondly the histopathological findings remained benign despite the fact that large nodular masses had recurred in the cecum and rectum, and thirdly the pathological changes were still confined to the gastrointestinal tract without developing systemic malignant manifestations.
