Objectives: To analyze the clinical presentation, and diagnostic and therapeutic implications in patients with retro-rectal tumors.
Methods: This paper reports two patients. Both patients had constipation and change in bowel habits, and the physical examination revealed the retro-rectal neoplasia. One of the patients had rectal intra-luminal invasion due to a schwannoma and underwent a transanal excision, with subsequent recurrence that required a combined abdomino perineal resection due to invasion of the tumor to the anorectal angle. The second patient had a teratoma and had a good outcome after a trans-sacral resection of the neoplasia.
Conclusions: Clinical suspicion is imperative to diagnose these rare tumors. Treatment of choice is complete resection of the tumor. Localization of the neoplasia, as evidenced by image studies will help to decide the best surgical approach.
