Malignant tumors of the small bowel (SB) represent 1-2% of the neoplasms of the digestive system, and 30 to 50% are adenocarcinomas, more frequently located in the duodenum [1,2]. Other primary tumors of the SB are lymphoma (15-20%), carcinoid tumors (5-24%) and sarcoma. The four mentioned tumors account for 95% of the malignant SB lesions [3]. Kanthan et al. [2] conclude that malignant and benign lesions of the duodenum are rare, and there could be coexistence of those types of tumors, stressing the importance of early diagnosis of malignant lesions for an adequate patient management [2].
