Retroperitoneal paraduodenal unicentric Castleman disease: case report and review of the literature.

Castleman disease is a rare and benign disorder, characterized by enlarged lymph nodes and angiofollicular lymphoid hyperplasia. We report a case of a 57-year-old male, who was admitted to our surgical department because of a retroperitoneal nodular mass measuring about 4 cm in maximum diameter, incidentally discovered on a radiologic exam performed for the onset of vague abdominal pain with posterior irradiation. The patient was subdue to laparoscopic removal of the mass and no intra- and post-operative complications were recorded.

An unusual association between pancreatic cancer and Purtscher-like retinopathy: Presentation of a unique case.

Introduction: Purtscher's retinopathy causes sudden loss of vision of varying severity, secondary to head injury or chest compression. Its pathophysiology is unclear. Purtscher's-like retinopathy has more attenuated clinical and objective features and can be associated with many non-neoplastic pathologies.

Appendicular schwannoma Review of the literature on a rare benign tumor often mistaken for hyperplasia.

Introduction: Appendicular schwannoma is a rare benign neoplastic proliferation of the appendicular Schwann cells. It is often asymptomatic until it occludes the appendicular lumen thus causing appendicitis-like symptoms.

Evidence Acquisition: The neoplastic proliferation of the Schwann cells, although benign, may rarely degenerate into a malignant neoplasm, thus denoting the importance of diagnosis.

Offending staple as an unusual but preventable cause of internal hernia with bowel obstruction Case report and review of the Literature.

In the laparoscopic era, the use of the stapler is a common practice and it adds to the possible causes of post-operative bowel adhesions with obstruction. In this study, we reviewed the Literature in order to study the pathogenesis and the incidence of bowel obstruction after using the laparoscopic stapler. Furthermore, we report a case of a woman who went to our observation for incoming bowel obstruction after laparoscopic ileal resection.

Ergonomics in laparoscopic surgery.

Background And Objectives: Laparoscopic surgery is a widely used surgical technique, whose benefits either for patients or for surgeons are well-recognized. Despite the rise in the use of this technique, the ergonomics of the operating room is still very low. The consequence is that injuries and illness related to laparoscopic surgery are present.
