Introduction: Although major portion of intestinal length is contributed by small intestine, neoplastic processes involve it less commonly as compared with large intestine. Yet a variety of tumors can occur and the study was done to study their histomorphology.

Methods: This study is carried out in the department of pathology, Sardar Patel Medical College and associated group of hospitals, Bikaner for a period of 28 months.

Results: Only one case (8.33%) of benign tumor (hamartomatous polyp) is recorded out of total 12 cases. Among malignancies adenocarcinoma comprised highest percentage (66.67%). Gastrointestinal stromal tumor (GIST), carcinoid and secondary malignancy recorded as single cases (8.33%) for each. 8 cases were male and 4 were female (M:F = 2:1). Numbers of cases were same (3 for each) in 5^th, 6^th and 7^th decade of life in this study.

Conclusion: In small intestine majority were adenocarcinomas and duodenum was the commonest site.
