Ischemic fasciitis in a mobile elderly patient: A case report

Area of Science:

• Pathology
• Dermatology
• Oncology

Background:

• Ischemic fasciitis (IF) is a rare pseudosarcomatous lesion.
• Typically affects debilitated or immobilized elderly patients.

Observation:

• A 76-year-old mobile man presented with a 33-mm subcutaneous lesion on his back, suspected to be soft-tissue sarcoma.
• The lesion involved the latissimus dorsi muscle and had been growing for 2 months.

Findings:

• Biopsy revealed spindle or stellate cells in a myxofibrous stroma with fibrinous deposits.
• These histological features suggested a diagnosis of Ischemic Fasciitis.
• The lesion spontaneously resolved 5 months post-biopsy.

Implications:

• Fibrin-like deposits in myxofibrous stroma may be a key diagnostic marker for Ischemic Fasciitis.
• This case expands the clinical presentation of IF to include mobile elderly individuals.
• Understanding IF's unique presentation aids in differentiating it from soft-tissue sarcomas.
