Abstract
This paper presents a case of immature teratoma with gliomatosis peritonei (GP) in a child with a discussion on the necessity of postoperative chemotherapy.
A 14-year-old female was admitted to the hospital because of abdominal fullness lasting for 2 years. A tumor mass occupying entire the abdomen with smooth surface and slight movability from side to side was palpated. Serum levels of tumor markers, CA19-9 and α-fetoprotein were as high as 224U/ml and 22.9ng/ml, respectively, Increased serum levels of CA125 and α-fetoprotein were noted. A plain abdominal X-ray film revealed a huge mass with calcification in whole peritoneal cavity. Abdominal ultrasonography and CT visualized a well-defined tumor shadow with calcified, solid and cystic lesions. These findings suggested an ovarial teratoma. In the operation, the tumor was the left ovarial tumor, and there was many nodules in the peritoneum and serosa of the duodenum. Pathologically, the tumor was immature teratoma (grade 1), and the nodule was mature glial cell (grade 0). Chemotherapy was not performed. The elevated CA125 and a-fetoprotein levels were normalized rapidly postoperatively. These have been no signs of the recurrence, as of 14 months after the operation, and she is enjoying school-life.
