Dysgerminoma associated with pregnancy

From a review of 26 reported case (our case being the 27th) of dysgerminoma associated with pregnancy, several salient facts are evident. Torsion and incarceration are common among these rapidly enlarging tumors. Obstetrical complications occurred in nearly half and fetal demise in one quarter of the reviewed cases. Our case was typical of patients presenting with this vexed problems: The patient was under 25 (as were 70%); nulliparous (as were 67%); and the tumor appeared confined to one ovary (as in 89%). Authorities are in dispute as to the treatment of stage IA dysgerminomas, and the association of pregnancy complicates this debate even further. The results of conservative treatment in this series were jarring: There were recurrences in 30% of the 23 stage IA tumors, and the recurrences were all following unilateral oophorectomy. In our case, the grossly normal contralateral ovary was infiltrated with dysgerminoma cells. While treatment of a young woman with a dysgerminoma of 1 ovary is a matter of perplexity, we believe that a unilateral operation should be limited to those women who desire above all earthly things to retain their childbearing capacity.
