'Myositis' affects which part of the body?
Inclusion body myositis a skin rash not seen in polymyositis or sIBM. It may have different root causes unrelated to either polymyositis or sIBM. Mutations in valosin-containing protein (VCP) cause multisystem proteinopathy (MSP), which can present (among others) as a rare form of inclusion body myopathy. Inclusion body myositis Inclusion body myositis (IBM) [my-oh-SIGH-tis] is the most common inflammatory muscle disease in older adults. The disease is characterized by slowly progressive weakness and wasting of both distal and proximal muscles, most apparent in the finger flexors and knee extensors. There are two types of IBM: sporadic (sIBM), which is more common, and hereditary
Myositis ossificans fast-growing process. If clinical or sonographic findings are dubious and extraosseous sarcoma is suspected, biopsy should be performed. At histology, detection of the typical zonal phenomenon is diagnostic of myositis ossificans, though microscopic findings may be misleading during the early stage. The radiological features of myositis ossificans are ‘faint soft tissue calcification within 2–6 weeks, (may have well-defined bony margins by 8 weeks) separated from periosteum by lucent zone and on CT, the characteristic feature is peripheral ossification’. Since myositis ossificians is more common in those with bleeding disorders, the formation of bone in soft tissue is thought to be
