Teratoma in pregnancy: a case report

Mature teratoma is a common complication of pregnancy. To the best of the authors' knowledge this is the largest teratoma in pregnancy documented in the literature.

A 19-year-old woman, gravida 1, at 14 weeks' gestational age with a 37-cm fundal height, was found to have a 30 x 28 x 17 cm mass on ultrasound. She underwent an exploratory laparotomy, and a teratoma was excised.

A teratoma that could limit the growth of an intrauterine pregnancy, is suspected for rupture or torsion, is causing severe pain, and/or may be suspicious for malignancy should be excised.
