Area of Science:

  • Oncology
  • Pathology
  • Immunology

Background:

  • Ovarian fibrosarcoma is a rare ovarian malignancy.
  • Cytokine production by tumors can influence clinical presentation and disease progression.

Observation:

  • A Japanese woman presented with epigastric pain, fever, leukocytosis, and thrombocytosis, initially lacking hormonal abnormalities.
  • The resected ovarian tumor showed spindle-shaped cells, mast cell infiltration, and scattered tubules.
  • Recurrence occurred 14 months later with similar symptoms and elevated serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha).

Findings:

  • The recurrent tumor exhibited similar histology but lacked tubules.
  • Tumor cells were immunoreactive for vimentin, IL-6, TNF-alpha, and alpha-inhibitin.

  • Reverse transcription-polymerase chain reaction confirmed mRNA expression of IL-6, IL-10, TNF-alpha, and stem cell factor in the recurrent tumor.

    • Implications:

    • This case highlights a rare ovarian fibrosarcoma with atypical clinical features due to multi-cytokine production.
    • Understanding cytokine expression in ovarian fibrosarcoma is crucial for diagnosis and management.
    • Further research is needed to elucidate the role of these cytokines in fibrosarcoma pathogenesis and patient outcomes.
