Background: Polyembryomas are rare, immature germ cell malignancies ch
aracterized by numerous embryo-like bodies in association with mature
and immature teratoma structures and primitive embryonic tissue. The p
urpose of this paper is to present a patient in whom surgical staging
and postoperative serial tumor markers and imaging studies were used t
o determine management. Case: A 43-year-old woman with a stage IA poly
embryoma was followed with serial alpha-fetoprotein and hCG assays, as
well as serial abdominal and pelvic computed tomography (CT) scans, f
ollowing surgical staging and a total abdominal hysterectomy and bilat
eral salpingo-oophorectomy. Chemotherapy was not given because the pat
ient's tumor markers declined steadily into the normal range and imagi
ng studies revealed no evidence of recurrent disease. Conclusion: Wome
n with polyembryomas surgically staged and confined to one ovary may b
e followed with serial tumor markers and diagnostic imaging techniques
to avoid aggressive cytotoxic chemotherapy.
