A Case of Myxoinflammatory Fibroblastic Sarcoma

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.
