Area of Science:

  • Oncology
  • Pathology
  • Surgical Oncology

Context:

  • Low-grade fibromyxoid sarcoma (LGFMS) is a distinct subtype of soft-tissue sarcoma.
  • This rare tumor presents diagnostic challenges due to its deceptively benign histological appearance.
  • Accurate differentiation from other soft-tissue neoplasms is crucial for appropriate patient management.

Purpose:

  • To present two cases of low-grade fibromyxoid sarcoma.
  • To describe the characteristic histological features of LGFMS.
  • To emphasize the importance of distinguishing LGFMS from other soft-tissue tumors.

Summary:

  • Two cases of LGFMS are detailed: a 31-year-old male with scapular tumor and recurrence, and a 45-year-old female with a thigh neoplasm.
  • Histological examination revealed low cellularity, spindle-shaped fibroblastic cells, alternating fibrous and myxoid areas with a whorled pattern, and prominent vascularity in myxoid regions.
  • Tumor cells lacked mitoses and atypia, showing positive staining for vimentin and occasional actin.

Impact:

  • Provides valuable insights into the presentation and histology of low-grade fibromyxoid sarcoma.
  • Aids pathologists and clinicians in recognizing and differentiating LGFMS from other soft-tissue lesions.
  • Contributes to the understanding of this rare sarcoma, potentially improving diagnostic accuracy and patient outcomes.
