Abdominal wall hernias after trauma have been recognized for more than a century, with the first case reported as occurring after a fall. Traumatic abdominal wall hernias (TAWHs) after blunt trauma are uncommon. The timing of definitive repair, early or delayed, is not clear. We report a case on TAWH and mesenteric avulsion, highlighting the reasons for immediate or delayed repair. A single case study can hardly be considered as a basis for profound changes in the management of post traumatic hernias. However, damage to all layers of the abdominal wall indicates high-energy trauma. In such cases, the damage is not, in all probability, limited to the integumentary system. For the moment, the timing of surgery in any TAWH should be considered differently according to the trauma, the wall defect, clinical and radiological findings, associated injuries, and the clinical status of the patient.

A primary hemangiopericytoma (HP) of the bone is rare, because the vast majority of these tumors arise in soft tissue. This report presents a case of a hemangiopericytoma in the sacrum (S1-S2) with extension to the retrorectal space. Only a few cases of osseous hemangiopericytomas in the sacrum and involving the retrorectal space have so far been reported. The difficult diagnosis of HP and the surgical strategy was chosen according to the location of the lesion in the sacrum and retrorectal space. A local excision was indicated. A sacral resection should be considered for tumors below S4. This report demonstrated the safety of this strategy. Adjuvant radiotherapy is useful in HP. The value of chemotherapy is still doubtful, although patients with high-grade tumors or metastatic spread seem to gain substantial benefit. Due to the often unpredictable behavior of this neoplasm, extended follow-up is strongly recommended.

Les tumeurs pseudopapillaires et solides du pancréas (TPPSP) sont des tumeurs rares, d'étiopathogénie encore incertaine, et surviennent surtout chez la jeune femme. Leur extension locale et à distance est rare, et leur pronostic reste bon surtout après exérèse complète. Nous rapportons une nouvelle observation chez une jeune femme, révélée par une douleur. L'échographie et le scanner ont permis de poser le diagnostic. Le traitement chirurgical était conservateur et consistait à une tumorectomie. L'étude histologique confirma le diagnostic de TPPSP. Mots clés Pancréas · Tumeur papillaire et solide · Résection chirurgicaleAbstract Solid pseudopapillary tumors (SPT) of the pancreas are rare exocrine pancreatic tumors. Their etiology is unknown and they occur most commonly in young women. Local invasion and metastatic evolution is rare in these tumors and their prognosis is excellent after complete surgical resection. We report of SPT in a young female revealed by abdominal pain. The diagnosis of the cystic tumor was based on abdominal ultrasound and CT data. The surgical treatment was conservative and consisted of a tumorectomy. Histological study confirmed the diagnosis of SPT of the pancreas.
