Seven patients with adeno-carcinoma of the small intestine were seen over a period of five years. Four were localized to the duodenum, the jejunum was involved in two and the ileum in one. Abdominal pain, weight loss, anemia and obstruction were the most common presenting complaints. Endoscopy was the primary diagnostic modality for the duodenal tumours. Diagnostic accuracy of barium contrast examination was 83%. Curative resections were performed in two patients and palliative surgery in the rest.

Sarcomatoid carcinoma of the small intestine is an extremely rare malignant neoplasm that usually has a poor prognosis. We report a case of sarcomatoid carcinoma arising in the small intestine in a 62-year-old man who was hospitalized for abdominal pain. Computed tomography revealed wall thickening of the small intestine. The resected specimen showed a gray-whitish solid mass with hemorrhage and necrosis. Microscopically, the tumor was composed of pleomorphic spindle and discohesive polygonal cells with frequent mitosis. No carcinomatous component was recognized. Immunohistochemistry revealed coexpression of cytokeratin and vimentin by the tumor cells, whereas expressions of C-kit, CD34, HMB-45, smooth muscle actin, and desmin were negative. The diagnosis was sarcomatoid carcinoma of the small intestine.

A 41-year-old female was admitted into hospital due to recurrent abdominal pain with bloating. An enteroscopy was carried out and stenosis in the lower jejunal lumen was identified. This led to a diagnosis of small bowel obstruction caused by inflammation. During the laparotomy, the resection and anastomosis of a narrow segment of small intestine was performed. In combination with the results of immunohistochemical analysis, the postoperative pathology indicated the presence of a poorly differentiated/undifferentiated carcinoma of the small intestine, which was considered to have arisen from breast cancer. Postoperative examination showed bilateral breast masses, and the pathology of the right breast tumor biopsy prompted the diagnosis of invasive lobular carcinoma. A breast MRI was reviewed following five cycles of XT chemotherapy and the evaluation was stable disease (SD). Since the mass was not sensitive to chemotherapy, a bilateral modified radical mastectomy was performed, and postoperative pathology confirmed the mass to be primary bilateral invasive lobular carcinoma.
