Abstract
Carcinoma of the small intestine is a rare entity, especially mucinous type. This is a case report of mucinous carcinoma of the small intestine.
A 90-year-old woman was admitted to our hospital because of abdominal pain and abdominal distension. An abdominal X-P showed dilatation of the small intestine and niveau formation. An ileus tube was inserted. It revealed stenosis of the ileum about 5cm proximal to the ileum end. Stenosis caused by adehesion after appendectomy was the most likely diagnosis. After trans endoscopical dilatation, her symptoms disappeared. One month later, the same symptoms developed and chest CT scan showed multiple lung metastasis. Operation was performed with a diagnosis of malignant tumor of the ileum. Ileo-cecal dissection was done, when a tumor was found in the ileum 5cm proximal to the Bauhin valve. Histological findings of the resected tumor were consistent with villous adenocarcinoma at the muscle layer and carcinoma cells in large mucous lakes infiltrated to the subserosal layer and lymphatic metastasis were shown.
