“…The posterior approach is recommended for a low-lying tumor under the sacral promontory or below the level of the fourth sacrum. Transanal endoscopic microsurgery provides a good visual field for accurate excision and the laparoscopic approach has a advantage of a magnifying effect in the narrow pelvis without evidence of malignancy [16,17]. In our case, the patient was diagnosed as double tailgut cysts without malignancy in pelvic MRI and PET scan.…”

Tailgut cyst, also called retrorectal hamartoma, is a rare congenital lesion and is usually located anterior to the sacrum and posterior to the rectum. We report a case of double tailgut cyst (presacral and precoccygeal hamartoma). A 62-yearold female visited the hospital complaining of anal pain and pressure in the perianal area for one month. Digital rectal examination revealed a round mass with hard consistency in the lateral and posterior part of rectum 5 cm from the anal verge. Pelvic magnetic resonance imaging showed two cystic and solid presacral masses (lateral and posterior part of rectum) compressing the rectum. The patient underwent surgical resection for pathologic diagnosis. At operation, two masses were located in the left presacral space without invasion to adjacent organs and soft tissue. Pathologic examination revealed double tailgut cysts without malignant transformation. A differential diagnosis of perirectal cystic hamartoma includes epidermal cysts, cystic teratomas, dermoid cysts, anal gland cysts, sarcoma and rectal duplications. Regional inflammatory process frequently complicates this lesion and perirectal fistula can develop. Tailgut cyst also has a malignancy potential, with development of adenocarcinomas. To establish a definite diagnosis and prevent complication, complete surgical resection is recommended.

Due to the rarity and large diversity of the primary retrorectal tumors (RTs), the diagnoses are often difficult and they can be misdiagnosed. We present our experience in light of scarce information available on the clinical manifestations of RTs. The retrospective study included 17 patients diagnosed as RTs between January 2004 and January 2014. Demographic characteristics, length of symptoms, clinical findings, diagnostic methods, evaluations on the treatment procedures and postoperative periods, pathology, complications, and length of hospital stay were recorded. A mean of 1.7 of patients were diagnosed with RTs annually in our hospital. Patients comprised 12 females and 5 males. Pain and discomfort were the most common symptoms at presentation. All the lesions were evaluated by using magnetic resonance imaging (MRI) and computed tomography (CT), and all the patients were treated operatively. Based on the preoperative MRI or CT findings, an anterior approach was performed in 7 patients, a posterior approach in 6 patients, and combined approach in 4 patients. Mean size of tumors was 9.2 6 4.3 cm. Epidermoid cyst (n ¼ 8) was the most common tumor. Except for 1 case of liposarcoma, 16 tumors were confirmed to be of benign nature in histologic examination. Mean length of hospital stay 12.4 6 6.8 days. Retrorectal tumors are heterogeneous and lead to diagnostic difficulties. A high index of clinical suspicion is needed for diagnosis. Preoperative imaging may be helpful in determining the course of treatment. Total excision of a retrorectal tumor may alleviate pressure symptoms and confirm the diagnosis.
