Objective: To identify the prevalence of retrorectal tumors and to describe their clinicopathological characteristics. Setting: General Hospital of Mexico ''Eduardo Liceaga'' (third level health care center). Design: Retrospective, observational descriptive, cross-sectional study. Statistical analysis: Percentages as summary measure for qualitative variables. Patients and methods: Review of clinical files to identify those patients with a diagnosis of retrorectal tumor in the period from 2000 to 2012. Analyzed variables were: age, sex, symptoms, treatment, final histopathological report, and prevalence of the disease. Results: From a total of 28,452 first-time consultations from January 2000 to December 2012, six patients were identified with retrorectal tumors, four of them were men (66-6%); average age was of 57.8 years (46-69). The main symptoms were constipation in six (110%), tenesmus in five (83.3%), anal pain in three (50%), lumbar pain in three (50%), rectorrhagia in two (33.3%), and weight loss in two (33.3%). Average length of symptoms was of 21.8 months. All patients were operated; three through an abdominal approach (50%) and three through a posterior approach (50%), transoperative bleeding, longer in-hospital stay and minor complications were encountered in the abdominal approach group. The most frequent tumor was the chordoma in four patients (66.6%) followed by a pleomorphic sarcoma in one patient, and a tumor of the gastrointestinal stroma in one patient. Follow-up was of 4.6 months (4 to 6). Conclusions: Retrorectal tumors have a low prevalence presenting with heterogeneous clinical characteristics due to the type of tumors that can occur in this region. The most frequent malignant tumor was the chordoma.
