Aggressive myxoinflammatory fibroblastic sarcoma with multiple site metastases

Area of Science:

• Oncology
• Pathology
• Surgical Pathology

Background:

• Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare soft tissue neoplasm.
• MIFS typically presents as a slow-growing superficial lesion, often misdiagnosed.
• Histological features include spindle cells, pleomorphic bizarre cells, and inflammatory infiltrates.

Observation:

• A rare case of MIFS in a 38-year-old male is presented.
• The patient exhibited extensive local spread to the ankle joint and bones.
• Multiple synchronous metastases were observed in the lung, rib, and vertebra.

Findings:

• The presented MIFS case demonstrated aggressive clinical behavior.
• Rapid growth and extensive metastases were characteristic of this rare presentation.
• This contrasts with the typically indolent nature of MIFS.

Implications:

• This case underscores the importance of considering MIFS in differential diagnoses, even with aggressive features.
• Awareness of rare aggressive presentations is crucial for timely diagnosis and management.
• Further research into the aggressive variants of MIFS may be warranted.
