Ischemic fasciitis in a mobile elderly patient: A case report

Ischemic fasciitis (IF) is a rare pseudosarcomatous lesion usually occurring in physically debilitated or immobilized, elderly patients. The current case presents a 76-year-old mobile man with IF on his back. The 33-mm subcutaneous lesion, focally involving the latissimus dorsi muscle, had been slowly increasing in size for 2 months and was clinically suggested to be a soft-tissue sarcoma. The fragmented biopsy specimens showed a chiefly scattered proliferation of spindle or stellate cells with plump nuclei within myxofibrous stroma. Zonation was not evident, but the lesion contained fibrinous deposits. These findings indicated a possible diagnosis of IF. The lesion spontaneously disappeared 5 months after the biopsy. The presence of fibrin-like deposits within myxofibrous stroma could be a hallmark for the correct diagnosis of IF.
