Growing Teratoma Syndrome : A Woman with Mixed Germ Cell Ovarian Tumor

Abstract

We reported a 24 year-old woman presented with pelvic mass who underwent right salpingo-oophorectomy. Histopathological examination revealed mixed endodermal sinus tumor and dysgerminoma. During chemotherapy with PEB regimen, although the serum alpha-feto protein level decreased, pelvic examination with confirmation of ultrasonography revealed further enlarged pelvic mass. Exploratory laparotomy and excision of tumor mass was performed and microscopic examination of specimen revealed mature teratoma. This patient was free of disease 3 months after diagnosis.
