[Primary retroperitoneal synovial sarcoma revealed by hemorrhagic shock].

Introduction: Primary retroperitoneal synovial sarcoma is a rare malignant neoplasm that typically arises in young adults. We report here an unusual presentation of this tumor during hemorrhagic shock and retroperitoneal hematoma.

Case: A 31-year-old man was admitted complaining of acute violent pain of the right lower abdominal quadrant.

[Spiegelian hernias. Report of 51 cases].

We describe 51 cases of Spiegel's hernias, and report a critical review of the relevant literature. The patients presented with an isolated mass in 17 cases, abdominal pain in 17 cases, and a complication in 14 cases (intestinal occlusion in 8, incarceration in 6). The hernia was discovered fortuitously by compute tomography in three cases.
