Extragonadal teratomas in women and adolescent girls: A systematic review.

Eur J Obstet Gynecol Reprod Biol 2021 May 7;262:134-141. Epub 2021 May 7.

Department of Obstetrics and Gynaecology, National University Hospital, 5 Lower Ridge Road, 119074, Singapore. Electronic address:

Introduction: Extragonadal teratomas (EGTs) are rare and the commonest intra-abdominal subtype is omental. We present two cases: 1) a parasitic omental teratoma likely secondary to auto-amputation of an ovarian teratoma with subsequent omental reimplantation and 2) an omental immature teratoma likely due to parthenogenetic activation of displaced primordial germ cells. We subsequently conduct a systematic review to characterise EGTs. Read More

Laparoscopic Management of Primary Omental Torsion.

Case Rep Surg 2021 24;2021:5536178. Epub 2021 Feb 24.

Centre Hospitalier Sud Francilien, Corbeil-Essonnes, France.

Primary omental torsion is an unusual condition, known for its rarity and for the particularity of being intraoperatively diagnosed, in nearly all cases. At the clinical evaluation, this pathology commonly mimics other etiologies of acute abdomen. Hemoperitoneum and necrosis of the omentum are rarely associated with the omental torsion, but when the association is found, then it means that the vascular injuries are irreversible and the required surgical procedure may be far more complex than simple devolvulus.

Epiploic appendagitis of the vermiform appendix--An unusual mimic of acute appendicitis.

Radiol Case Rep 2021 Mar 18;16(3):511-515. Epub 2020 Dec 18.

Department of Clinical Imaging, Hamad General Hospital, Apt 12, Building 15, Haya complex, street 889, zone 37, Doha, Qatar.

Epiploic appendagitis is a condition resulting from ischemia or necrosis involving the appendage epiploica either due to torsion or spontaneous thrombosis of the venous outflow. It is one of the myriad causes of acute abdominal pain and can masquerade clinically as appendicitis, omental infarction, sclerosing mesenteritis and even diverticulitis. Epiploic appendagitis of the vermiform appendix is a rare entity, clinically indistinguishable from appendicitis. Read More
