Introduction: Retrorectal tumors constitute a rare and heterogeneous group of neoplasms, which are characterized by being located in the so-called retrorectal space. In most cases these are benign lesions. The main imaging test for its characterization and planning its therapy is magnetic resonance imaging. Surgery is generally the treatment of choice, often without preoperative anatomopathological studies, given the potential risk of malignancy of these tumors and the appearance of compressive symptoms during the course.

Clinical case: The clinical case of a 34-year-old patient is reported, who consulted for a history of pain in the dorso-lumbar region of months of evolution, accompanied by rectal pain. Magnetic resonance imaging of the abdomen and pelvis was requested, which revealed a retrorectal tumor with imaging characteristics suggestive of teratoma. The resolution was a surgical procedure through a perineal approach, with the diagnosis being confirmed by deferred pathological anatomy.

Conclusion: Retrorectal tumors are rare lesions in adults that represent a diagnostic and therapeutic challenge. The surgical approach depends above all on the tumor size and the relationship with the S3 sacral vertebra. In the case presented, a mature retrorectal teratoma, the perineal approach is a valid therapeutic option that allowed correct exposure and tumor resection.
