The retrorectal space is an uncommon seat for neoplastic masses. Retrorectal hamartoma or tailgut cyst (TGC) is an uncommon developmental cystic lesion occurring in this space which mostly occurs in middle-aged females. We recently cared for a 16-year-old girl who presented with vague lower abdominal pain and occasional constipation. Per rectal examination revealed an extraluminal mass bulging from posterior rectal wall. Preoperative radiological investigations revealed by suggested it to be a mature cystic teratoma. The patient underwent exploratory laprotomy with en masse excision of the cyst. Histopathological examination of the specimen showed it to be a TGC. This case highlights the possibility of a TGC as a differential for retrorectal cystic lesions and the need to completely excise them given the possibility of future malignant transformation.

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.

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.

Tailgut cysts are rare congenital cysts that develop from the embryological remnants of the gut. They are usually found in the retrorectal space. In most of the cases, they are asymptomatic.

Tailgut cyst or retrorectal cystic hamartoma is a rare congenital lesion, thought to arise from a portion of the embryological hindgut, usually benign, with no or unspecific symptoms, mainly diagnosed in middle-aged women. Complete surgical resection of the cyst is recommended to avoid complications and confirm the diagnosis. In this report, we present our experience in the successful endoscopic management of a tailgut cyst, outlining the endoscopic resection technique and discussing under what conditions this approach may be applicable.
