“…To the best our knowledge this may be the first case of myositis ossificans circumscipta to be documented in this location. Most authors have associated this lesion with trauma, [2][3][4][5][6] however Ogilvie-harris 4 documented a case without a history of trauma. In this reported case no history of trauma could be elicited.…”

“…8 Surgical excision is the main stay of treatment for myositis ossificans circumscripta. 2,3,9,10 Previous reports of this pathology occurring in the head and neck region are case reports involving the temporalis 5,9 and the masticatory 3,10,11 muscles. We therefore present a case of limitation of ocular movement from myositis ossificans circumscripta in a very unusual location; the orbital plate of the frontal bone with no previous history of trauma.…”

Myositis ossificans circumscripta is a pathological condition characterized by formation of bony tissue within the skeletal muscles following repeated trauma. A case of myositis ossificans circumscripta of the supra-orbital region in a 25-year-old man is presented and the pertinent literature is reviewed. To the best our knowledge this benign lesion has not been reported previously in the orbital region the world literature. Clinically the patient presented with a swelling and proptosis of the right eye. Radiologically there was a rounded opacity with well defined margin. Lesion was initially misdiagnosed as a fibroosseous lesion; however microscopic examination indicated matured myositis ossificans. Lesion was excised via a bicoronal flap. Careful clinical, radiological and pathologic evaluation is required to make this uncommon diagnosis in an unusual location such as the supra-orbital region to avoid unnecessary surgical mutilation of the patient. Key words: Myositis ossificans, supraorbital RésuméLa Myosite circumscripta ossificane est un état pathologique caractérisé par la formation de tissu osseux dans le muscle squelettique à la suite des traumatismes répétés. Un cas de la myosite circumscripta ossificane de la région supra orbitale chez un homme âgé de 25 ans est ici présenté et aussi la pertinence de la littérature est révisée. A notre connaissance, cette lésion bénigne n'a pas été signalée précédemment dans la région orbitale de la littérature du monde. Cliniquement le patient s'est présenté atteint du gonflement et du propose de l'oeil droit. Radiologiquement, il y avait une opacité arrondie avec des marges bien définies. Lésion a été au départ mal diagnostiqué comme une fibro-lésion osseuse ; toutefois, l'examen microscopique avait indiqué la myosite ossification mûre. Lésion a été excisée par l'intermédiaire d'un bicoronal flap. Prise en charge clinique, radiologique et évaluation pathologique est nécessaire pour faire ce diagnostique rare dans une situation inhabituelle telle que la région supra orbitale afin d'éviter les mutilations chirurgicales évitable chez le patient Mots clés Myosite ossificane, supra orbitale

“…(1)(2)(3) It is characterized by symmetric congenital malformation of the hands and feet and a progressive heterotopic ossification of the soft connective tissues. In many cases, MOP occurs in childhood, and the movement of the joints gradually becomes restricted, leading to ankylosis (2,3). In some cases the patient may die of pulmonary complications due to restricted movement of the respiratory muscles (2).…”
