[Cervical myositis ossificans. A case report]

This is the case of a middle-aged male with a slow growing lateral cervcal painful tumour, and without previous history of local trauma. Radiological testing reveals an ossifying soft tissue lesion without any osseous compromise. The lesion is completely resected, and the histological result is of ossifying myositis. It is an osseous tumour non neoplastic that originates within muscle and in particular the flexors of the inferior extremities and thigs or in the soft tissues. The incidence within the head and neck region is low (20%). There is an hereditary progressive form, Munchmeyer's disease, and another circumscribed, which can be subdivided in traumatic or atraumatic.
