Heterotopic ossification (HO, also termed myositis ossificans) is the formation of extra-skeletal bone in muscle and soft tissues. HO is a tissue repair process gone awry, and is a common complication of surgery and traumatic injury. Medical strategies to prevent and treat HO fall well short of addressing the clinical need. Better characterization of the tissues supporting HO is critical to identifying therapies directed against this common and sometimes devastating condition. The physiologic processes of osteogenesis and angiogenesis are highly coupled and interdependent...

The formation of lamellar bone in the soft tissues, where bone normally does not exist, is called myositis ossificans. However, it would be more accurate to describe as myositis ossificans the involvement of skeletal muscles and as ectopic or heterotopic ossification the involvement of soft tissues in general. The lesion is subdivided in genetic and non-genetic or acquired types. Myositis or fibrodysplasia ossificans progressiva is a debilitating rare genetic disorder. Clinical suspicion of the disease in the newborn on the basis of malformed great toes may lead to early clinical diagnosis, confirmatory diagnostic genetic testing and avoidance of iatrogenic harmful procedures...

BACKGROUND: Nonunion is a rare but severe complication following forearm fracture in skeletally immature patients. The purpose of this study is to describe a case series of pediatric forearm nonunions treated at our Institute. MATERIALS AND METHOD: We retrospectively reviewed medical charts and radiographs of healthy children affected by post-traumatic nonunion of the forearm, from April 1992 to July 2015. An overall series of 15 cases was included in the study...

Intra-abdominal myositis ossificans, also known as heterotopic mesenteric ossification, defines the formation of bone-like lesions inside the abdominal cavity. It is a rare medical condition, usually following abdominal surgery or trauma. A 55-year-old male presented for closure of a Hartmann's colostomy, created 6 months ago because of sigmoid adenocarcinoma. Intraoperative findings consisted of an elongated bone-like lesion attached on the peritoneum and protruding inside the abdominal cavity, while two more stiff calcified nodules were found in the mesocolon...

Myositis ossificans progressiva (MOP) is an autosomal dominant disorder. There is a progressive ectopic ossification and skeletal malformation, mainly in the connective tissue of muscle. The diagnosis is based on the clinical findings and radiological demonstration of the skeletal malformations. A 38-year-old female patient was admitted to our department with progressive increase of the thigh. Results of laboratory studies were normal. The radiography of the right thigh showed multiple intramuscular calcifications...

BACKGROUND: Neurogenic Myositis Ossificans (NMO) is a rare disabling pathology characterized by peri-articular heterotopic ossifications following severe peripheral or central nervous system injuries. It results in ankylosis and vessels or nerves compressions. Our study aimed to describe the pre-operative findings of patients with NMO of the hip using biphasic computerized tomography (CT). METHODS: Between 2006 and 2012, we retrospectively analyzed 101 consecutive patients with hip NMO...

A 15-yr-old sexually intact female vampire bat ( Desmodus rotundus ) was diagnosed with myositis ossificans traumatica of the abdominal wall. The bat presented with a large ulcerated firm mass along the abdomen. Radiographs and cytology were performed, followed by surgical exploration. The mass was determined to be nonresectable and the bat was euthanized. Histopathology showed severe necrotizing, degenerative, and pyogranulomatous myositis with osseous and cartilaginous metaplasia, fibrosis, and ulceration, which were consistent with myositis ossificans traumatica...

Pathological conditions can give rise to calcifications within oral mucosa representing either a local or systemic disturbance. Inflammation, trauma, debris acting as nidus and vascular lesions have been attributed as principal causes for occurrence of calcifications within the oral mucosa. Occurrence of multiple calcified thrombi (phleboliths) is considered pathognomonic for hemangiomas and vascular malformations in the oral and maxillofacial region. Isolated occurrence of phlebolith in oral mucosa though very rare, especially without any underlying vascular lesions, can be diagnostically challenging...

Objective: To investigate the role of SATB2 in the pathological diagnosis and differential diagnosis of osteosarcoma. Methods: Immunostaining of SATB2 was performed in 47 cases of osteosarcomas, 5 osteoblastomas, 4 fibrous dysplasias, 5 myositis ossificans, 10 chondroblastomas, 8 chondrosarcomas, 5 Ewing sarcomas, 5 undifferentiated pleomorphic sarcomas, 6 fibrosarcomas and 2 leiomyosarcomas. Results: All osteoblastomas (5/5) and myositis ossificans (5/5), 83.0%(39/47) of osteosarcomas and 2/10 of chondroblastomas showed nuclear immunoreactivity for SATB2...

Myositis ossificans circumscripta (MOC) is a rare condition characterized by nontumoral heterotopic ossification of the soft tissues. This condition affects young subjects, occurring mainly after trauma. It is ubiquitous, predominantly located in girdles and limbs. We report the case of a young patient with paravertebral MOC without traumatic context; the aim of this study was to recall diagnostic criteria and imaging aspects.

A calcification mass was incidentally found in the soft tissue of a patient who had a history of trauma to the extremity during examination. The patient had no symptom. The pathological analysis of the mass revealed it was an early-phase synovial sarcoma (SS). The diagnosis was made before the onset of symptoms and proper surgical intervention was performed. Therefore, in case of a <1 cm lesion clinically suspicious of myositis ossificans, SS should be taken into consideration as a possible diagnosis.

Myositis ossificans (MO) is a benign soft tissue lesion with non-neoplastic heterotopic bone formation. MO in the intermediate and mature stages can be easily diagnosed if characteristic imaging findings such as a peripheral zonal pattern of ossification with variable thickness is observed. However, it is difficult to correctly diagnose early MO because it can mimic malignancy clinically, radiologically, and histopathologically. We report a case of early pseudosarcomatous phase of non-traumatic MO with atypical imaging findings...

PURPOSE: Humero-ulnar external fixation has been proposed to treat complex supracondylar humeral fractures in children. It facilitates fracture reduction and reduces the risk of ulnar nerve lesion, which can occur after cross pinning. METHODS: In a ten year period, 28 children have been operated on in our centre by humero-ulnar external fixation, for Lagrange-Rigault stages III and IV supracondylar humeral fractures. The data about fracture management and early follow-up were obtained from our medical database...

BACKGROUND: Myositis ossificans is a benign, tumor-like lesion characterized by heterotopic ossification of soft tissue that usually affects the elbow and thigh. At different stages of maturity, it show similar histologic appearances with sarcomatous lesions or maturing bone. Misdiagnosis can result in unnecessary radical treatment. CASE REPORT: A 50-year-old woman with dorsal forefoot soft tissue mass was diagnosed as myositis ossificans after surgical excision and confirmed by a histopathological examination...

Myositis, which means inflammation of the muscles, is a general term used for inflammatory myopathies. Myositis is a rare idiopathic autoimmune disease. It is believed that environmental factors such as virus, bacteria, parasites, direct injuries, drugs side effect can trigger the immune system of genetically susceptible individuals to act against muscle tissues. There are several types of myositis with the same systemic symptoms such as muscle weakness, fatigue, muscle pain and inflammation. These include dermatomyositis, juvenile dermatomyositis, inclusion-body myositis, polymyositis, orbital myositis and myositis ossificans...

In most of the cases trauma is the leading etiology and the nontraumatic myositis ossificans (MO) is a very rare condition. We present an MO case without any trauma occurring. A 36-year-old female patient with a history of pain and restriction of range of motion of the left hip was admitted. Hip motions were restricted with 10-60° of flexion, 10° of internal rotation, 20° of external rotation, 10° of abduction, and 10° of adduction. There was no history of trauma and familial involvement. The biopsy of the lesion revealed mature bone tissue confirming our diagnosis of MO...
