proliferative myositis

A rare intramuscular inflammatory condition with a pseudosarconomatous appearance, which is characterised by rapid growth and diffuse infiltration of the muscle of the upper extremities and trunk, often in a background of trauma. Proliferative myositis has a characteristic “checkerboard” pattern of distribution in the muscle fibres and surrounding connective tissue, which can be identified by ultrasonography and computed tomography and is confirmed on the pathology specimen.
