title: [Retroperitoneal leiomyosarcoma].
abstract: We report a case of retroperitoneal leiomyosarcoma recurrence. This entity is rare, < 0.2% of all tumours in humans and 25-30% of retroperitoneal sarcomas. The diagnosis is usually delayed in relationship with scarce clinical signs which favorite the development of great tumour volume before diagnosis. The treatment is surgical, with wide margins excision. Radiotherapy and chemotherapy are not adequates for treatment of this pathological entity.
