“…Certains auteurs proposent des marges de sécurité de 5 mm [4,23]. Une approche chirurgicale plus large, voire interruptrice, est préconisée pour les tumeurs volumineuses et infiltrantes [24,25]. La reconstruction sera fonction de la taille de la résection.…”

Résumé -Introduction :Le fibrome ossifiant juvénile (FOJ) est une tumeur bénigne très agressive localement avec une forte tendance à la récidive. Observation : deux cas présentant des caractéristiques cliniques, radiologiques et pronostiques différentes sont rapportés. Le 1 er cas est celui d'une patiente âgée de 18 ans qui s'est présentée avec une tuméfaction prémaxillaire gauche évoluant depuis 1 an. La particularité de ce cas a été la survenue de multiples récidives malgré des interventions itératives. Le second cas concernait une enfant de 7 ans qui s'est présentée avec une tuméfaction génienne haute indolore évoluant depuis 4 mois, dont le traitement a consisté en une exérèse de la lésion. Le suivi post-opératoire à 2 ans n'a révélé aucune récidive. Discussion : Le FOJ est une tumeur fibro-osseuse peu fréquente par rapport aux fibromes ossifiants conventionnels. Ses caractéristiques sont la production d'une matrice trabéculaire ou psammomatoïde, la forte prévalence chez les jeunes patients et une prédilection pour les os des sinus paranasaux, la région péri-orbitaire et le maxillaire. Les deux cas présentés corroborent les données épidémiologiques rapportées dans la littérature. Abstract -Juvenile ossifying fibroma: report of two cases and review of the litterature. Introduction:Juvenile ossifying fibroma is an uncommon fibro-osseous tumor affecting the facial bones. It is a locally aggressive benign tumor with a high tendency to recur. Observation: This article reports 2 cases with different clinical, radiological and prognostic features, both of which were diagnosed as juvenile ossifying fibroma. The first case is a woman of 18 years who presented with swelling of the left premaxilla lasting for 1 year. The special feature of this case was the occurrence of multiple recurrences despite many operations. The second case is a 7-year-old child who presented with painless swelling lasting for 4 months. The treatment consisted of surgical exeresis of the lesion. The post-operative follow-up at 2 years showed no recurrence. Discussion: Juvenile ossifying fibroma is an infrequent fibro-osseous tumor. Its characteristics are trabecular or psammomatoid matrix production, high prevalence in young patients, and a predilection for periorbital and maxillar bones. The 2 cases presented corroborate the epidemiological data reported in the literature on the various aspects of this type of tumor.

“…Histologically, the juvenile variants share a similar stroma but PsJOF is characterized by innumerable small spherical/lamellated ossicles resembling psammoma bodies of meningiomas set in cellular fibrous tissue while TrJOF contains trabeculae of woven bone with coarse lacunae, swollen osteocytes and a lining of plump osteoblasts [14]. The separation of the two types is only on the basis of histological examination.…”

Juvenile psammomatoid ossifying fibroma is a rare benign fibro-osseous tumor of the gnathic and extragnathic craniofacial bones, particularly the periorbital, frontal and ethmoid bones. It is slowly progressive with aggressive local growth, invasion and destruction of the surrounding tissue, bone erosion and recurrence after surgical excision. It is distinguished from the other fibroosseous lesions by its age of onset, clinical presentation and aggressive behavior.

“…The diagnosis between these two entities may be challenging, because they share similar features. There are four main clinical subtypes of FD: monostotic (affects one bone, and accounts for 85% cases of FD), polyostotic (affects multiple bones), McCune-Albright syndrome in which multiple disseminated lesions of bone are accompanied by skin hyperpigmentation and endocrine disturbances; and osteofibrous dysplasia (Brannon and Fowler 2001;Smith, Newman et al 2009). …”

“…The juvenile variants of ossifying fibromas share many similarities, but they have been distinguished on the basis of their histopathological features, site, and age of recurrence (Shields, Peyster et al 1985;Noudel, Chauvet et al 2009;Smith, Newman et al 2009). Their location is also different: JPOF arises mainly around paranasal sinuses and orbits, whereas JTOF usually affects the maxilla.…”

“…Despite its benign features, they can be locally invasive, causing significant morbidity, and fatal consequences may be induced by intracranial extension (Baumann, Zimmermann et al 2005;Cruz, Alencar et al 2008;Bohn, Kalmar et al 2011;Linhares, Pires et al 2011). However, a surgical approach is dictated more by anatomic location and tumor size than by histologic subtype (Shields, Peyster et al 1985;Hartstein, Grove et al 1998;Smith, Newman et al 2009). …”
