Retrorectal Tumors

Abstract

Primary neoplasms of the retrorectal (presacral) space are very rare. These lesions may be congenital or acquired, benign or malignant. They often arise with subtle clinical symptoms, or they may be found incidentally during evaluation for other conditions. Preoperative imaging can provide useful information for operative planning; however, it does not eliminate the need for surgery. Approaches for resection include posterior only and combined abdominoperineal, depending on the characteristics of the lesion. Successful treatment of these enigmatic lesions requires extensive knowledge of pelvic anatomy and expertise in pelvic surgery.

Histopathological diagnostic dilemma in retrorectal developmental cysts: report of a case and review of the literature

“…Epidermoid cyst, dermoid cyst, duplication cyst, cystic hamartoma (tailgut) and teratoma are considered in the differential diagnosis of cystic lesions of the rectal region (4,5). Imaging techniques such as ultrasonography, computerized tomography and magnetic resonance imaging are performed for the differential diagnosis of retrorectal cystic lesions.…”

“…Developmental cysts, most of them being congenital, are lesions frequently localized in the retrorectal region (1,2). The major types of retrorectal cysts are epidermoid cyst, dermoid cyst, rectal duplication cyst, rectal cystic hamartoma and teratoma (3)(4)(5). Tailgut cyst, also known as retrorectal cystic hamartoma, is a congenital lesion of embryologic tailgut origin, located in the retrorectal space (2,4,6).…”

“…Duplication cyst is lined by epithelium of respiratory and gastrointestinal systems and it contains two layers of organized muscle layers (3,5,6,10). In reports related to this topic, the cyst epithelium has similar features to those written in classical textbooks in most of the cases.…”

Sacrococcygeal neoplastic lesions

“…Adenocarcinoma is the most frequent histological finding in these cases. [16] Teratoma The prevalence of sacrococcygeal teratoma is one out of 40.000 live births with a significant female predilection 4-1. The most common site of origin is believed to be the sacroccocygeal area, followed by ovaries, neck, retroperitoneum, mediastinum, testicles and central nervous system.…”

A Rare Coexistence of Retrorectal and Ovarian Cysts: A Case Report

“…These lesions’ incidence rate is one in approximately 40,000 admissions (1-3). Most cases are congenital, and the developmental cysts are the most common congenital entity encountered in the retrorectal space (4, 5).…”
