Pediatric Dysgerminoma: Understanding a Rare Ovarian Tumor

Introduction Pediatric dysgerminoma is a rare malignant ovarian tumor, accounting for only 1%–2% of all ovarian cancers. Though most commonly seen in young women, its occurrence in pediatric patients is exceptionally rare. In this blog, we explore a unique case of pediatric dysgerminoma, shedding light on its clinical presentation, diagnosis, and treatment.

Clinical Presentation and Diagnosis A 12-year-old girl presented with a three-week history of pelvic pain and progressive abdominal swelling. Physical examination revealed a distended abdomen with a palpable abdominopelvic mass. Imaging studies, including ultrasonography and MRI, confirmed a solid heterogeneous mass measuring 20 cm × 16 cm × 8 cm, originating from the pelvis. Tumor markers showed elevated Lactate Dehydrogenase (LDH) levels, which supported the diagnosis.

Treatment and Management The patient underwent a right salpingo-oophorectomy. Histological examination and immunohistochemical studies confirmed the diagnosis of dysgerminoma. Given the early stage of the tumor, no adjuvant treatment was required. Instead, regular follow-ups, physical examinations, and LDH assays were scheduled to monitor the patient’s progress.

Key Findings from the Study

  • Dysgerminomas are rare but represent the most common malignant germ cell tumors in young patients.
  • Symptoms include abdominal pain, distention, and a palpable mass.
  • MRI and ultrasonography are valuable diagnostic tools.
  • Surgical intervention is the primary treatment, with fertility-preserving options in early-stage cases.
  • Regular follow-up is critical to monitor for recurrence.
