Les schwannomes retrope'ritone'aux [a propos de 2 cas]

ABSTRACT

Based on two cases of retroperitoneal schwannomas, the one being benign and followed- up during 13 years, the other malignant, the authors discuss here some clinical, paraclinical and therapeutic features of these conditions. The retroperitoneal localization of schwannomas is uncommon. They usually occur between 30 and 50 years without sex prevalence. The clinical symptomatology is marked by signs of urinary and digestive compressions. The morphological examinations can reveal the tumour. They also specify its seat, its nature and its relationship. The schwannomas is malignant in the third of cases. Its treatment is mainly surgical. The prognosis depends on the histologic nature and extent of the tumoral resection. The following-up must be continuous in time since the belated recurrences are possible
