Abstract:
Jejunum-ileum stromal tumors give diagnostic and therapeutical problems, especially with regard to histopathological identification and biological behavior. These tumors are very rare in all case report. After gastric stromal tumors these ones are the most frequent of all alimentary tract. They are often incidentally found; because of their potential transformation, they have to be treated by respecting oncologic eradication standards and observing prognostic criteria based on a correct histopathological evaluation (neoplasm localization and dimension, its structure, presence of cytological atypisms, mitotic index, ploidia, surgical resection). Then there has to be a good follow-up program.

The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...

Small Intestine
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique C-shape wraps...
