Background: Presacral tumors are a rare and diverse group of lesions that originate in the presacral space. Given its rarity, it is difficult to reach an early diagnosis of tumors presenting as difficult to manage. 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. Conclusion: Presacral tumors are an uncommon worldwide, being difficult to diagnosis and management.
