This case report details a rare instance of multifocal extragonadal seminoma, initially presenting in the mediastinum and later in the brain. It highlights the aggressive nature and potential for recurrence of this rare germ cell tumor.

Area of Science:

  • Oncology
  • Neurology
  • Pathology

Background:

  • Germ cell tumors (GCTs) are neoplasms that arise from primitive germ cells.
  • Extragonadal GCTs, particularly seminomas, can occur in various locations, including the mediastinum and central nervous system.
  • Multifocal GCTs are uncommon, especially in extragonadal sites.

Observation:

  • A 16-year-old male initially presented with a mediastinal germ cell tumor (seminoma).
  • The patient underwent combined modality treatment including surgery, radiotherapy, and chemotherapy.
  • Nine years post-treatment, he developed an intracerebral germ cell tumor involving the suprasellar ventricles and pineal region.

Findings:

  • The patient received further radiotherapy and chemotherapy after partial surgical removal of the intracranial tumor.

  • Despite treatment, the patient died 8 months later, likely due to secondary cardiovascular complications.
  • This case represents the first documented instance of multifocal extragonadal seminoma, suggesting a potential for widespread dissemination.

    • Implications:

    • This case underscores the importance of long-term surveillance for patients treated for extragonadal germ cell tumors.
    • It highlights the potential for late recurrence and multifocal presentation of seminomas.
    • Further research is needed to understand the biology and optimal management strategies for multifocal extragonadal germ cell tumors.
