A 78-year-old woman presented with an abdominal mass diagnosed by ultrasound and computed tomography. The patient underwent a laparotomy, during which a retroperitoneal tumor adherent to the cecum wall was identified. Microscopically, it showed spindle-cell proliferation in whorls, with low mitotic count (2 per 50 high-power fields) and was strongly positive for S-100 protein and vimentin. The final diagnosis was benign schwannoma of the cecum and no further treatment was required. Large intestine schwannomas are extremely rare tumors and only a few cases of schwannoma of the cecum have been reported to date.

Appendiceal tumours encompass a wide spectrum of differential diagnoses and frequently present with clinical features of appendicitis. We report the case of a 43-year-old woman who presented with epigastric pain, dyspepsia and bloating. An atypical right para-iliac mass was detected on abdominal ultrasound, and computed tomography (CT) identified an appendiceal tumour.

Evidence Acquisition: The neoplastic proliferation of the Schwann cells, although benign, may rarely degenerate into a malignant neoplasm, thus denoting the importance of diagnosis.
Laparoscopic-Endoscopic "Rendezvous" Procedure in Pediatric Gastrointestinal Surgery-Case Series.

Laparoscopic-endoscopic "rendezvous" procedures were introduced in surgery for common bile duct stone treatment but are now widely used in other fields of abdominal surgery. An endoscopist navigates a surgeon during the same operative procedure and, thus, enables a better visualization of the location, resection margins, bleeding control, less thermal damage, etc. Here, we present case series of 11 patients that were treated using a "rendezvous" procedure for gastrointestinal lesions on different parts of the gastrointestinal tract such as juvenile polyps on the colon (transversum, ascendens, cecum, sigma), leiomyomatosis of the stomach, Peutz-Jeghers intestinal polyposis, hyperplastic gastric polyp, ectopic pancreatic tissue in the stomach, gastric trichobezoar, and gastric schwannoma.
