Abstract

A retroperitoneal enlarging mass was detected and resected in a 24‐year‐old nulliparous woman after fertility‐preserving surgery and adjuvant chemotherapy for a malignant germ cell tumor (MGCT) of the right ovary. This enlarging mass contained only a mature teratoma component. Alpha‐fetoprotein, which was elevated to 21236.6 ng/mL before the initial surgery, persisted within normal after the completion of adjuvant platinum‐based chemotherapy. The patient was diagnosed with growing teratoma syndrome. Growing teratoma syndrome originating from ovarian germ cell tumor is very rare. Only 15 cases have been reported. Surgical resection and histological confirmation of growing mass after MGCT treatment is essential before conducting salvage chemotherapy.

We report the cytogenetic findings in a case of mixed germ cell-sex cord-stromal tumor of the ovary in a 5-month-old girl. Monosomy 22 was observed as the sole karyotypic abnormality. This result was confirmed by comparative genomic hybridization, which revealed no additional chromosomal imbalances.

Primary alpha-fetoprotein secreting ovarian tumors have been detected in pregnancy by markedly elevated midtrimester MSAFP accompanied by sonographically visualized adnexal masses. We present a recurrent mixed germ cell tumor manifesting only as a moderately elevated MSAFP screen. A 23-year-old para
