Case Report
A 23-year-old nulliparous woman presented to us with complaints of pain in the abdomen of 6 months duration. She underwent laparoscopy for a right adnexal mass 4 years before her present complaints. There was a 10-cm ovarian cyst; cystectomy with ovarian reconstruction was done, and it was a benign cystic teratoma as determined by histopathologic study. Laparoscopic excision of the cyst was done. The patient was symptom free for 4 years and presented to us with abdominal pain. She described the
Discussion
Teratomas arise from germ cells that originate in mature gonads. During early fetal development migration of germ cells along the hindgut (route of mesentery) toward the genital ridge (primitive gonad) takes place. These totipotential cells may give rise to a variety of tissues originating from the 3 primitive embryonic layers. Three proposed theories on the cause of these extragonadal sites exist: (1) primary dermoids originating from displaced germ cells; (2) dermoids developing in a

Extragonadal teratomas in women and adolescent girls: A systematic review
2021, European Journal of Obstetrics and Gynecology and Reproductive BiologyCitation Excerpt :Nevertheless, this mechanism is difficult to prove as displaced, undifferentiated germ cells have never been found [9,29]. Finally, the presence of synchronous or previous ovarian teratomas in 20 cases (29.0 %) and multiple teratomas in three cases [30,49,50] provokes the alternative consideration that these may be explained by seeding and implants from a prior ovarian teratoma. Like ovarian teratomas, EGTs carry the risks of cyst accidents such as torsion [9,51,52] and rupture [53], containing immature components or undergoing malignant transformation in any of the cell lines [54–58].
Laparoscopic Port Site Dermoid Cyst: A Rare and Unusual Presentation
2020, Journal of Minimally Invasive GynecologyA case of extragonadal teratoma in the pouch of douglas and literature review
2015, Journal of Minimally Invasive GynecologyCitation Excerpt :We performed a PubMed search using the key words “extragonadal” or “parasitic,” “teratoma,” “Douglas,” or “cul-de-sac,” which rendered 19 reports. A summary of the 19 cases of parasitic dermoid cyst in the pouch of Douglas is given in Table 1 [12,14–31]. Patient age ranged from 23 to 83 years, and no peak of onset was observed.
Completely free and mobile intra-abdominal tumor
2014, Surgery (United States)Citation Excerpt :Intra-abdominal calcified cyst hydatids should also be considered as part of a differential diagnosis when such cases present. Dermoid cysts, which seem to occur most commonly after ovarian tumors, are believed to result from the autoamputation and reimplantation of an ovarian dermoid cyst.3,5 Such tumors commonly present as the cause of abdominal pain, with the tumor being evident as an abdominal or pelvic mass during a physical examination.
