Appendiceal GIST: report of an exceptional case and review of the literature.

Gastro-intestinal stromal tumors (GISTs) of the appendix are a rare entity. To date, only eight cases has been described in the literature, most of which have been of the benign type. We report a new case of an appendiceal GIST in a 75-year-old man.

Meckel's diverticulum: an exceptional cause of vesicoenteric fistula: case report and literature review.

Unlabelled: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can cause complications in the form of ulceration, hemorrhage, intussusception, intestinal obstruction, perforation and, very rarely, vesicodiverticular fistulae as noted in six previously reported cases. 66-year-old woman was presented with an enterovesical fistula.

Huge desmoid tumor of the anterior abdominal wall mimicking an intraabdominal mass in a postpartum woman: a case report.

Desmoid tumors are benign neoplasms that most often arise from muscle aponeurosis and have been associated with both trauma and pregnancy. The etiology of desmoids has not been determined. We report the case of anterior abdominal wall desmoid tumor in a female patient with previous history of cesarean section.

Gastrointestinal bleeding due to an erosion of the superior mesenteric artery: an exceptional fatal complication of pancreatic pseudocyst.

The erosion of a pancreatic pseudocyst into an adjacent artery is a rare and highly lethal complication of pancreatitis with reported death rates of 12% to 40%. The majority of patients had bleeding from the splenic artery, the gastroduodenal artery and the anterior pacreaticoduodenal artery. Exceptionally, some cases with bleeding from the superior mesenteric artery, or hepatic artery were reported.

Histopathologic characteristics and short-term outcomes of colorectal cancer in young Tunisian patients: one center's experience.

Introduction: Colorectal carcinoma (CRC) is generally a disease of persons older than 40 years. Concerning younger patients, controversies still exist regarding features and prognosis of CRC. We performed this study to characterise CRC in young patients (≤ 40 years) as well as to evaluate short-term outcome in comparison with older patients (>40 years) with CRC.

A wandering spleen presenting as a hypogastric mass: case report.

Wandering spleen is a rare condition characterized by the absence or underdevelopment of one or all of the ligaments that hold the spleen in its normal position in the left upper quadrant of the abdomen. It is an uncommon clinical entity that mainly affects children. Among adults it most frequently affects women of reproductive age, in whom acquired laxity of the splenic ligaments is usually the cause.

Internal supravesical hernia - a rare cause of intestinal obstruction: report of two cases.

Supravesical hernias develop at the supravesical fossa between the remnants of the urachus and the left or right umbilical artery. They are exceptional and are often the cause of intestinal obstruction. We report two cases of surgically proven internal supravesical hernias presenting with small bowel obstruction.

Exceptional cause of bowel obstruction: rectal endometriosis mimicking carcinoma of rectum--a case report.

Endometriosis with intestinal serosal involvement is not uncommon in women of childbearing age. However, endometriosis presenting as colon obstruction is rare and occurs in less than 1% of cases. The Lack of pathognomonic signs makes the diagnosis difficult, mostly because the main differential diagnosis is with neoplasm, even during the intervention.

Intussusception caused by an inverted Meckel's diverticulum: a rare cause of small bowel obstruction in adults.

Adult intussusception due to Meckel's diverticulum is an uncommon cause of intestinal obstruction. However, the surgeon should still be suspicious of this condition since the non specific symptoms and the rarity of it make a preoperative diagnosis uncertain. Considering the secondary nature of adult intussusception and the necessity of early surgical intervention to avoid morbidity and mortality, we report one case of intussusception due to Meckel's diverticulum in an adult.

A rare cause of proximal intestinal obstruction in adults - annular pancreas: a case report.

Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the descending part of the duodenum. It is one of the few congenital anomalies of the gastrointestinal tract which can produce symptoms late in life. In adults, the factors initiating symptoms are recurrent pancreatitis, duodenal stenosis at the site of the annulus, or duodenal or gastric ulceration.

[Abscess of obturator internal muscle].

The abscess of obturator internal muscle is a rare disorder. The literature states only sporadic cases. Because of its rarity, the diagnosis is often late.
