BACKGROUND/AIMS: Retrorectal masses are rarely encountered in surgical practice, and they arise from congenital remnants, and from osteogenic, neurogenic, inflammatory, or metastatic processes. The majority of these masses are benign but many can be malignant, so they need to be treated with aggressive surgical management. METHODS: In this case series, eight patients with retrorectal masses of various etiologies are described, with particular emphasis on diagnosis and surgical treatment. RESULTS: In our series, we noted one duplication cyst, one tailgut cyst, one epidermoid cyst, one teratoma, one gastrointestinal stromal tumor, one epithelial malignant tumor, one inflammatory mass, and one retrorectal mass of as yet unknown origin. In three patients, complete excision via posterior sagittal approach was performed, one underwent abdominoperineal en-block proctectomy, two were only biopsied for neoadjuvant therapy, and two are waiting for operation. CONCLUSIONS: Surgery is the main treatment of choice, and the surgical strategy should be decided according to the localization and nature of the retrorectal mass.
