Myositis Ossificans (MO) is an unusual pathological entity still largely unknown, characterized by dystrophic calcification leading to heterotopic ossification of intramuscular connective tissue. The masticatory muscles are exceptionally involved. Four distinct types of myositis ossificans have been described: MO Progressiva, which is a genetic disorder involving several muscular groups, MO Circumscripta, limited to a single muscle and generally due to calcification of an intramuscular haematoma following severe trauma and progressive ossification, MO Pseudo-malignant limited to soft tissue and not associated to any trauma, MO associated to paraplegia. A case of circumscribed myositis ossificans of the masseter muscle is reported in a 62 years-old woman.

Abstract
Myositis Ossificans (MO) is an unusual pathological entity still largely unknown, characterized by dystrophic calcification leading to heterotopic ossification of intramuscular connective tissue. The masticatory muscles are exceptionally involved. Four distinct types of myositis ossificans have been described: MO Progressiva, which is a genetic disorder involving several muscular groups, MO Circumscripta, limited to a single muscle and generally due to calcification of an intramuscular haematoma following severe trauma and progressive ossification, MO Pseudo-malignant limited to soft tissue and not associated to any trauma, MO associated to paraplegia. A case of circumscribed myositis ossificans of the masseter muscle is reported in a 62 years-old woman.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
