“…Several investigators have reported the usefulness of fi ne-needle aspiration biopsy for retrorectal cysts. 13 Oyama et al 14 performed aspiration cytology and a core biopsy for a carcinoid tumor arising from a retrorectal tailgut cyst. However, a fi ne-needle aspiration biopsy may lead to dissemination of the tumor cells when a retrorectal cyst is neoplastic in nature.…”

Retrorectal epidermoid cyst in an elderly woman: Report of a case

et al. 2008

View full text Add to dashboard Cite

An epidermoid cyst is a common occurrence in the skin. Such a cyst occurring in the retrorectal space, however, is extremely rare. We herein present a case of retrorectal epidermal cyst in a 67-year-old Japanese woman. She reported no symptoms and a perirectal mass behind the lower rectum was accidentally detected by computed tomography (CT). Contrast CT and magnetic resonance imaging revealed a cystic mass (76x70x63 mm) with a slightly enhanced thin wall which was attached to the lower rectum. The patient underwent surgery via a posterior approach. The mass was exposed after an excision of subcutaneous fat and was firmly adhered to the anal sphincter muscle. The cystic mass was completely removed without a proctectomy. Histologically, the cyst was diagnosed to be an epidermoid cyst. The postoperative course was uneventful, and the patient was discharged on postoperative day 9. A diagnosis of retrorectal cystic tumor is difficult, and a complete resection is necessary for the treatment of such tumors.

“…There was no evidence of any mesenchymal element in our case, ruling out teratomas. Rectal duplication cysts show mostly columnar epithelium of the rectum, with well-developed muscle layers having a nerve plexus between them, instead of the focal disorganized muscle bundles seen in TGCs [5]. Our case showed a variety of epithelia with no evidence of any mesenchymal element.…”

“…Microscopic examination plays a very important role in the final diagnosis of retrorectal cystic mass. Epidermal and dermoid cysts are usually unilocular and show mostly squamous epithelia with keratin and dermal appendages, respectively [5]; our case was multiloculated and showed a variety of epithelia. Teratomas are composed of all three germ layers and contain epithelial as well as various kinds of mesenchymal elements such as nervous, cartilaginous, and bony structures [5].…”

Fine Needle Aspiration Cytology Diagnosis of Tailgut Cyst: A Rare Entity

Background: Tailgut cyst is a rare tumor believed to originate from small portions of the embryonic tailgut, which normally disappear in early fetal development. It is often misdiagnosed due to the general unfamiliarity with this entity and also because of its clinical presentation similar to other more common diseases such as perianal fistulas and abscesses. Case: The authors take this opportunity to report a case of tailgut cyst in a 21-year-old Saudi female. The patient had presented with painful low back swelling, which had been gradually increasing in size. The case was diagnosed by fine needle aspiration cytology (FNAC) as tailgut cyst and later confirmed by histopathology. Conclusion: Tailgut cysts are congenital cystic hamartomatous lesions, which are rare in occurrence. They are generally benign, but malignancy has also been reported, which is even rarer in occurrence. FNAC is an effective diagnostic tool, which if applied appropriately can be used for the early detection of rarer lesions such as tailgut cyst.

A tailgut cyst found accompanying rectal cancer: Report of a case

et al. 1995

View full text Add to dashboard Cite

Tailgut cysts are rare congenital lesions. To date, only four cases have been reported in Japan, and the occurrence of a tailgut cyst with rectal cancer has never been documented. We describe here the case of a patient in whom a tailgut cyst in the retrorectal space was associated with rectal cancer. Preoperative computed tomography scans and endorectal ultrasonography failed to identify the lesion as cystic, instead suggesting an involved lymph node. This case emphasizes the necessity for careful diagnosis of masses in the retrorectal space in patients with rectal cancer.
