Overview

Case report details diagnosis of myxoinflammatory fibroblastic sarcoma using histological analysis, highlighting its importance for accurate identification.

Key Points

  • To detail the clinical and histological features of myxoinflammatory fibroblastic sarcoma (MIFS) in a patient.
  • Clinical examination of a 2 cm subcutaneous nodule on the right upper arm.
  • Ultrasound imaging revealing a low-echo mass in subcutaneous fat.
  • Immunohistochemical staining to characterize cellular properties and confirm diagnosis.
  • Immunohistochemistry showed positivity for vimentin and α-SMA in some areas, and Ki-67 positivity in 50% of cells.
  • The patient was diagnosed with myxoinflammatory fibroblastic sarcoma based on histopathology.
  • While generally showing good survival rates, the local recurrence rate is relatively high.
