Overview

Case presentation reveals a rare high-grade immature teratoma with torsion, indicating diagnostic complexities.

Key Points

  • The aim is to present a rare case of high-grade immature teratoma in a young child and to highlight diagnostic challenges.
  • Case presentation of a 20-month-old girl with symptoms of vomiting and abdominal distension.
  • Imaging studies suggested a left-sided mass, but laparotomy revealed a right ovarian mass with torsion.
  • Salpingo-oophorectomy was performed to remove the affected ovary and mass.
  • Histopathological analysis confirmed a Grade 3 immature teratoma staged as FIGO Stage IA.
  • The patient had a high-grade immature teratoma with prominent neuroepithelial elements.
  • No metastasis was observed, and the tumor was classified as early-stage disease.
  • Successful complete resection led to favorable outcomes, though close follow-up is necessary.
