Extraovarian dysgerminoma in a pregnant woman: an extremely rare finding.

Extraovarian germ cell tumors are very rare and their occurrence during pregnancy is exceptional. In this case report an abdominal mass was shown by ultrasonography, during a routine monitoring of a 26-year-old pregnant woman. The patient was left under radiological control in the following months in order to bring the pregnancy to term. A few months after the delivery, the patient underwent surgery and a diagnosis of extraovarian (abdominal) dysgerminoma was made. To the best of our knowledge, there are only 3 other case reports describing an extra-gonadal dysgerminoma occurring during pregnancy. The aim of this study was to report an extremely rare tumor, whose management can be challenging first because this neoplasm has some differences from its ovarian and testicular counterparts. Furthermore, the occurrence during pregnancy makes the multidisciplinary approach mandatory since 3 distinct but not independent entities are involved (tumor, mother and fetus). [ABSTRACT FROM AUTHOR]
