Synchronus Multicentric Small Intestinal Adenocarcinomas: Report of a Case

Abstract

Small intestinal tumor is rare; even multiple adenocarinomas limited to the small intestine are extremely uncommon. Adenocarcinoma together with carcinoid tumours are the most common histological types of cancer of the small intestine but patients may present with other primary malignant tumours, including lymphoma and leiomyosarcoma. We report a case of multicentric synchronus small intestinal adenocarcinomas involving from duodenum to jejunum in a 50 year-old man. The patient is well in the past and no family history of malignancy. Chest X-ray had revealed mass lesion in the right upper lung. The pathology examination of echo guide aspiration showed negative. Capsule endoscope and push small intestinal endoscopy was performed and revealed three tumors from duodenum to jejunum. The pathology examination showed moderately differentiated adenocarcinoma. Surgical resection of all three tumors and the patient's abdomen symptoms subsided hence after. No tumor recurred during the follow up to three years after discharge.
