The authors report a rare case of jejunal Schwannoma which appeared as hematemesis and melaena. No preoperative test, even selective angiography, enabled a correct clinical diagnosis to be made. Only after explorative laparotomy and careful palpation of the small intestine was the bleeding lesion located. Resection and termino-terminal anastomosis were then performed. The preparation of immunohistochemical reactions now allow forms which were previously diagnosed in different terms to be precisely classified.

Schwannomas of gastrointestinal tract are rare, slow-growing tumors, usually benign, arising from gastrointestinal tract's neural plexus.

The incidence of small bowel schwannomas is extremely low. In the current literature, we found just a few reported small intestine schwannomas that were located in the duodenum, jejunum, or ileum. This study reports a surprising finding of a relatively large size ileal schwannoma in a patient whose preoperative magnetic resonance imaging described a tumour in the lesser pelvis probably derived from the right adnexa.

Clinical Presentation: A 31-year-old woman presented with impaired gastric emptying after gastrectomy for GS and was diagnosed with postoperative gastroparesis syndrome (PGS). The symptoms were slightly relieved after routine placement of the jejunal tube; however, symptoms such as dietary intolerance and impaired gastric emptying persisted.

Upper gastrointestinal bleeding (UGB) is a potentially fatal consequence of digestive disorders. There is a wide range of rare causes for UGB that can lead to misdiagnosis and occasionally catastrophic outcomes. The lifestyles of those who are afflicted are mostly responsible for the underlying conditions that result in the hemorrhagic cases.

Unlabelled: Small bowel tumours are rare, representing about 0.5% of all tumours and about 3% of gastrointestinal tract tumours. The low prevalence contrasts with the vast surface area of the small intestine, which accounts for over 90% of the surface area of the digestive tract.
