Department of Obstetrics and Gynecology, "Victor Babeş" University of Medicine and Pharmacy Timişoara, Romania, Eftimie Murgu Sq. no. 2, Timişoara, RO.

Rationale: Although dysgerminomas are relatively uncommon among all ovarian neoplasms, representing for only about 2%, they account for 32.8 percent of malignant ovarian germ cell tumors. Their association with pregnancy is extremely rare; due to the low frequency of occurrence, there are few recommendations regarding pregnancy management; therefore, it is important to discuss and summarize the treatment strategy.
