[Primary retroperitoneal tumors in adults: report of 11 cases]. / Les tumeurs rétropéritonéales primitives de l'adulte: à propos de 11 cas.

The primitive retroperitoneal tumors are tumors which diagnosis isolate and thus the prognosis is poor. The authors assess the resectability of these tumors and the therapeutic results. We performed a retrospective study during 5 years, 11 patients were reviewed, in the unit of visceral surgical emergency of UHC Ibn-Rochd in Casablanca. The median age was 44 years old. The revealing signs were pains (67%), abdominal mass (54%), and compressive signs in 78%. The diagnosis was based on the computerized tomography in 10 cases (90%), the ultrasound sonography in 3 cases, and the IVU in 3 cases when it was necessary. The treatment was surgical in all cases. The resection was curative in 58%, 1 patient received chemotherapy. Histologically, the mesenchymatous variety was the most frequent (68%) and almost malignant (80%), the ectodermic origin was noted in 3 cases, and the vestigial in 1 case. The long-term follow-up was characterized by recurrence in 4 cases and 3 patients were lost to follow-up. The prognosis of the primitive retroperitoneal tumors is poor, because of a late diagnosis, and the malignant, and recurrent potential of these tumors.

[Leiomyosarcoma of the inferior vena cava: a new case report]. / Léiomyosarcome de la veine cave inférieure: à propos d'une nouvelle observation.

We report on a new case of leiomyosarcoma of the inferior vena cava presenting as an abdominal mass. With the help of review of the literature, the value of modern imaging techniques is recalled. The treatment is exclusively surgical. The prognosis is poor due almost to the diagnosis delay.

[Pulmonary hamartoma: a case with a predominant leiomyomatous component]. / Hamartome pulmonaire. A propos d'un cas à composante léiomyomateuse prédominante.

We report a case of leiomyomatous pulmonary hamartoma observed in a 61-year-old patient who presented with chest pain. The chest x-ray visualized a benign opacity of the upper right lobe. Hamartoma is the most frequent benign bronchopulmonary tumor. Surgical resection is required. Imaging provides the diagnosis. Conservative surgery is generally possible. Prognosis is favorable.
