Ischemic Fasciitis (Atypical Decubital Fibroplasia)
This is yet another pseudoneoplastic process related to nodular fasciitis that represents an exaggerated response to ischemic injury. Most often it involves soft tissues over bony prominences. The patient is usually debilitated with limited mobility. The image shows an area of necrosis (upper left) surrounded by a zone of proliferating myofibroblasts and fibroblasts.
