Mature Teratoma of the Gastrohepatic Ligament

ABSTRACT

Teratomas are tumors composed of derivatives of all three germinal cell layers. They have been described in a variety of organs in both children and adults, most commonly in the gonads. Extragonadal intraperitoneal teratomas are very rare. We here report a case of a large mature teratoma of the gastrohepatic ligament in a 20-year-old woman. To the best of our knowledge, a teratoma of the gastrohepatic ligament has never before been described, although there are a few reports of teratomas arising from the greater and lesser omentum.
