A large mature cystic teratoma, a type of germ cell tumor, was successfully excised from a young woman's retroperitoneum. This rare retroperitoneal tumor presented as a significant abdominal mass, requiring surgical intervention.

Area of Science:

  • Oncology
  • Surgical Pathology
  • Radiology

Background:

  • Teratomas are germ cell tumors containing diverse tissue types from multiple embryonic germ layers.
  • Retroperitoneal teratomas are rare, particularly in adults, and can present as large abdominal masses.
  • Mature cystic teratomas are the most common type of germ cell tumor.

Observation:

  • A 20-year-old female presented with a large, long-standing abdominal swelling and back pain.
  • Imaging revealed a significant retroperitoneal complex cystic mass with calcifications and fat.
  • The mass measured approximately 14.3 × 14.1 × 17.4 cm.

Findings:

  • Exploratory laparotomy confirmed a large retroperitoneal tumor.
  • Surgical excision of the retroperitoneal mass was performed.

  • Histopathological examination confirmed the diagnosis of mature cystic teratoma.

    • Implications:

    • This case highlights the possibility of large extragonadal teratomas presenting in the retroperitoneum.
    • Successful surgical management of such complex masses is achievable.
    • Early diagnosis and complete excision are crucial for favorable outcomes in teratoma cases.
