Abstract
Growing teratoma syndrome (GTS) is rare clinical phenomenon occurring as a sequelae of a malignant germ cell tumor. We present the case of a 20-year-old woman who developed GTS after undergoing fertility-sparing surgery and chemotherapy for an immature teratoma. She underwent left salpingo-oophorectomy, right ovarian cystectomy, and disseminated tumor reduction during her primary surgery. The postsurgical histology report identified the tumor as an immature teratoma, grade 3, International Federation of Gynecology and Obstetrics (FIGO) stage IIIb. She subsequently received 3 cycles of chemotherapy consisting of bleomycin, etoposide, and cisplatin. At 17 months after the chemotherapy, follow-up computed tomography (CT) scan revealed an enlarged mass in her right paracolic gutter and a small peritoneal lesion in the pouch of Douglas. Her serum alpha-fetoprotein level was not elevated. These findings were compatible with GTS, but it was difficult to rule out a recurrent immature teratoma. Diagnostic exploratory laparoscopic surgery revealed the enlarged tumors that had been detected by the CT scan. Although there were multiple tumors in the pouch of Douglas, we were able to resect all of them laparoscopically. Histological diagnosis of the surgically resected specimens was of a mature teratoma, and so we concluded that this tumor was a GTS. Our experience suggests that laparoscopic surgery is an effective alternative diagnostic and therapeutic approach in cases suspicious of GTS where the disease is disseminated to the peritoneum.
