Retroperitoneal malignant schwannoma. A case report.

This is the 15th fully documented case of retroperitoneal malignant schwannoma in the English-language literature. The histogenesis and morphological features are described. Apart from recommending radical surgical resection with adequate tumour margins, the literature provides very little guidance on management. Our patient received adriamycin and dacarbazine as adjuvant therapy and is clinically without evidence of disease 6 months after definitive surgery.
