Abstract
|
|
|
|
A 32-year-old woman had been referred to our hospital for lower abdominal pain. Pelvic ultrasonography and magnetic resonance imaging revealed a huge solid mass with an internal cystic portion. The patient underwent a staging laparotomy and subsequent total abdominal hysterectomy with bilateral salpingo-oophorectomy, bilateral pelvic lymph nodes sampling, and total omentectomy. At staging laparotomy, a large omental mass was found. The tumor displayed the typical histological patterns observed in the yolk sac tumor. The alpha-fetoprotein (AFP) serum value on the 10th day after surgery was 11,576.67 IU/mL and decreased to 6.46 IU/mL after chemotherapy. At the end of the treatment, all the findings, including the AFP level, were normal. We report a case of primary yolk sac tumor of the omentum in a 32-year-old woman.
