A Rare Recurrence of an Immature Teratoma: A Case Report

Abstract

Case report: A 26-year-old woman who was previously diagnosed as immature, right ovarian teratoma, was presented to Hangzhou obstetrics and gynecology hospital. The patient had previously undergone a laparotomy and right salpingo-oophorectomy with partial omentectomy 14-year before. Initial laboratory tests showed the serum markers: cancer antigen (CA)-125 was 44.5IU/ml (increased) and CA199, AFP levels were normal. Sonographic examination revealed a complex mass, measuring 12.6cmx10.5cm x8.5 cm, behind the uterus. Magnetic resonance imaging (MRI) findings were in favour of teratoma, originated from the right adnexa, occupying pouch of Douglas. The patient underwent exploratory laparotomy with a right intraligamentary teratoma cystectomy along with residual omentectomy,andrandom peritoneal biopsies. The pathology revealed mature teratoma, glioma, with no malignant components.
