Bronchogenic cyst of the ileal mesentery: a case report and a review of literature.

Introduction: Bronchogenic cyst is a rare clinical entity that occurs due to abnormal development of the foregut; the majority of bronchogenic cysts have been described in the mediastinum and they are rarely found in an extrathoracic location.

Case Presentation: We describe the case of an intra-abdominal bronchogenic cyst of the mesentery, incidentally discovered during an emergency laparotomy for a perforated gastric ulcer in a 33-year-old Caucasian man.

Conclusions: Bronchogenic cyst should be considered in the differential diagnosis of subdiaphragmatic masses, even in an intraperitoneal location.

Unicentric Castleman's disease approached as a pancreatic neoplasm: case report and review of literature.

Castleman's disease is a rare lymphoproliferative disorder. Most cases occur in the mediastinum and the pancreatic localization is uncommon; currently there are only nine reported cases in the literature about peripancreatic localization. We report a case of a 62 years old man with a Castleman's disease mimicking a pancreatic neoplasm.

Mesenteric chylous cysts simulating a pelvic disease: a case report.

Mesenteric chylous cysts, also known as retroperitoneal chylomatous cysts, mesenteric lymphangiomas or chyloma of the mesentery, are extremely rare and their aspecific clinical presentation can mimic other diseases. In addition, imaging techniques, which are rarely helpful in the correct diagnosis, can demonstrate aspecific features. The Authors report the case of a 62-year-old woman admitted to the hospital for two incidental abdominal masses diagnosed during a yearly monitoring examination and considered to be large adnexal masses.

Preliminary study on radioguided sentinel node identification in colon cancer.

The purpose of this study was to prove the prognostic value of the sentinel node (SN) in colon tumors, and to validate radioguided surgery in identifying the SN. Nodal metastases are a strong prognostic factor in patients operated on for colon or rectal cancer, decreasing the 5-year survival rate by approximately 20 per cent and dropping it to 30 per cent. Unfortunately, of 50 per cent of patients judged to be nodal disease-free at surgery, about 20 to 30 per cent will die from a local tumor relapse or distant metastases within 5 years of diagnosis.
