Retrorectal cystic hamartomas ("Tailgut cysts") are rare developmental cysts that appear in the retrorectal space, arising from aberrant remnants of the post-anal primitive gut in case of an incomplete embryogenetic involution. We present the case of a 30-year-old woman with a history of chronic lower abdominal pain. Other digestive symptoms, like rectal fullness, constipation, pain on defecation, rectal bleeding or genitourinary obstruction symptoms, were not associated.

Retrorectal tumors, although rare, pose diagnostic and treatment challenges due to their nonspecific symptoms and complex anatomical location. This single-center case series reports short-term outcomes of laparoscopic transabdominal resection as a surgical approach for large retrorectal tumors. Between 2017 and 2020, five patients underwent this procedure.

Article Synopsis
  • Presacral tumors are rare, especially in children, and can come from different cell types that develop during embryonic growth.
  • A case study of a 13-year-old girl showed initial imaging suggested a tailgut cyst, but surgery revealed it was actually a mature cystic teratoma, which is unusual for her age.
  • The surgery required careful dissection due to adhesions, and the diagnosis highlights the importance of surgical exploration over just imaging to accurately identify and treat presacral masses.

Retrorectal cystic hamartoma (also known as tailgut cyst) is a congenital lesion that originates from debris from the embryonic caudal intestine. Incidentally diagnosed in more than half of cases, the treatment of choice is surgical resection. It is a very rare pathology whose oncological transformation constitutes a true pathological rarity.
