The aim of this paper is to describe a series of cases with respect to clinical features, diagnosis and management. Methodology: Collection of patients who were diagnosed with presacral tumors since 1988-2013. We reviewed the clinical, evolution, diagnosis, surgical approach, pathology and complications. Results: Nine patients were included in this study. 7 of the 9 patients had primary symptom is pain. The average evolution time was 9.8 months. Diagnosis was made with digital rectal examination in all patients and confirmed in 9 patients pelvic CT and pelvic MRI in 5 patients. Pathology: mature cystic teratoma (n = 3), chordoma (no: 1), epidermoid cyst (no = 1), low-grade fibrous histiocytoma (no = 1), fibromatosis ( no = 1), aggressive angiomyxoma (no = 1). The main surgical approach was the posterior (Kraske) in 6 patients and in 2 by laparotomy. 1 patient had no surgery took. Complete resection was obtained in 87%. No early postoperative complications present. Late complications in 1 patient (12 %) for intestinal obstruction. Was only 1 case of partial resection tumor recurrence.
