    • "Ovarian MCTs mostly occur in the pelvic cavity and are commonly observed in the pouch of Douglas and occasionally in the uterosacral ligament (17). In rare cases, masses have been identified in the presacral region (18,19). The location of a mass in the presacral region is likely to be due to gravitational effects on the relatively large mass size, the heterogeneous content of the mass that enables it to be squeezed and reshaped along with the surroundings during exogenic movements or compressions and the presence of a smooth outer layer with limited attachments, together with the heterotypic or displaced of the ovary.

    ABSTRACT: The current case report presents an account of a unique surgical procedure performed to remove an extremely rare occurrence of a transsacral abdominal mass from a 24-year-old female. The patient presented with subtle sacrococcygeal pain for two months and a presacral abdominal mass derived from the right ovary. The mass was misdiagnosed as a presacral tumor based on the results of magnetic resonance imaging (MRI) performed prior to the surgery. The patient also exhibited the symptoms commonly caused by a presacral mass, however, during the surgery, the mass was not initially located under the sacrum. An ultrasound examination and an analysis of an intraoperative frozen section indicated that the mass was a mature cystic teratoma (MCT) of the ovary, located in the peritoneal cavity between the rectum and uterus. The mass was successfully resected and removed from the affected ovary through the abdominal cavity via the sacral region. A pathological examination of the tumor section confirmed a diagnosis of a MCT of the ovary.

    • "In humans, sacrococcygeal teratoma is a neoplasm arising in the sacrococcygeal region [16] and there were suggestions that it originated from multipotential cells in Henson’s node, which migrates caudally to the coccyx. It is one of the commonest fetal neoplasms, but is rare in adults [17]. "

    ABSTRACT: A 10-month-old intact male cat with a clinical history of a large mass in the left perineal region was submitted to the surgery department. The mass had reportedly been present as a small swelling after birth. Cytological evaluation using a fine-needle aspirate showed eosinophilic keratinaceous debris, and was not convincing for the definitive diagnosis. Complete surgical excision was performed. Postoperative function and aesthetics were excellent. Based on gross and histological features the definitive diagnosis of the tumor was mature teratoma with ectodermal and endodermal components. After a follow-up period of 4 months, no signs of recurrence were evident. Surgical excision of the teratoma in our case was considered curative. A perineal location has not been previously reported in the cat and should be considered a rare condition in this species.

    ABSTRACT: Adult Sacrococcygeal teratomas are very rare with female preponderance. The manuscript is a review of this rare tumor presenting in adulthood and review of literature. We report a case of sacrococcygeal teratoma in an adult female complicated by acute urinary retention and intestine obstruction. She had a 26 year old mass at the same site excised 10 year before the current presentation. In conclusion sacrococcygeal teratomas are rare especially in adults and usually present in complicated state and with high incidence of recurrence.
