OBJECTIVE Retrorectal tumours are rare lesions in adults. The diagnosis of retrorectal lesion is often difficult and misdiagnosis is common. We present significant number of cases in view of scarce information available on this matter. METHODS 14 patients were treated at Vilnius university hospital "Santariskiu klinikos" Centre of abdominal surgery from 1997 to 2010. The case notes of patient...

Retrorectal lesions are rare entities. We report the complete clinicopathological details of an unusual retrorectal lesion composed of low-grade endometrioid adenocarcinoma and propose that this is a malignant change in pluripotent cells arising within a long-standing retrorectal tailgut lesion. To the best of our knowledge, this is the first case report of this malignancy in a retrorectal tail...

Tailgut cyst is a very rare lesion of the retrorectal space seemingly derived from embryonic remnants of the tail gut which often causes rectal signs and symptoms. A unique case of this lesion presenting as a subcutaneous mass lateral to the coccyx is hereby described

Tailgut cysts, also known as retrorectal cystic hamartomas, are rare developmental abnormalities that typically occur in the retrorectal space. They are believed to arise from remnants of the embryonic hindgut (Hjermstad and Helwig, 1988). They can present as incidental findings during routine examination but over half of patients are thought to present with symptoms. MRI has become the modalit...

BACKGROUND The aim of this study was to provide an overview of the literature on Tailgut cysts (TGCs) arising in the presacral space. MATERIALS AND METHODS We present a new case of presacral TGC and a literature review of English-language studies of presacral TGCs, accessed through the PubMed and Google Scholar databases. Keywords used were presacral or retrorectal tailgut cyst, presacral muc...

Retrorectal tumors are very rare but well defined pathological entities in the literature. Also, an extrasphincteric fistula is a very rare form of perianal fistula which makes our case a very unusual and rare one, especially by the fact that it was successfully treated with the first operation and without protective stoma formation. The patient was first treated in hospital for a retrorectal a...

etrorectal cystic hamartoma are rare tumors of developmental origin usually diagnosed as an incidental finding in adult patients. We present such a case in a 33-year-old lady who presented with acute retention of urine. Ultrasound abdomen showed a retrorectal cystic mass (15 x 10 cm), which, was confirmed on computerized tomography (CT) scan. Exploratory laparotomy via a lower midline incision ...

INTRODUCTION Retrorectal cysts are rare benign lesions which are frequently diagnosed in middle-aged females. According to their origin and histopathologic features, retrorectal cysts are classified as squamous-lined (dermoid or epidermoid) cysts, postanal gut (tailgut) cysts, and rectal duplications (enteric or enterogenous cysts, enterocystomas). Described in this case report is an extremely ...

Retrorectal epidermoid cyst is one of the developmental cysts which arise from remnants of embryonic tissues. We report a rare case of retrorectal epidermoid cyst, initially diagnosed as an ovarian tumor. Serum SCC value as tumor marker was elevated to the high level. Laparoscopy revealed ovaries, uterus and other pelvic organs were all normal. This tumor existed in the retroperitoneal cavity a...

BACKGROUND Retrorectal hamartoma, also known as tailgut cyst, is a rare tumor that arises from remnants of the embryonic postanal gut. The tumor occurs in the retrorectal space and may undergo malignant degeneration. METHODS The clinical information on a single patient with pseudomyxoma peritonei associated with a tailgut cyst was reviewed and a literature review of the subject performed. R...
