A large mass in the mandible of an eight year old child

Sekiz yaşındaki çocuğun alt çenesinde geniş bir kitle Çocukların yüzünde görülen şişlikler daha çok enfeksiyon, çene kistleri ve benign-malign tümörler nedeniyle oluşmaktadır. Ayırıcı tanıda bulguların başlaması, şişliğin gelişme hızı ve çocuğun yaşı göz önüne alınmalıdır. Fibroosseöz lezyonlar fibrosis ile karakterize, kemiğe, semente veya her ikisine benzeyen yapıda değişik oranlarda kalsifiye doku içeren lezyonlardır. Bu tür lezyonlar çenelerde genişlemeye ve şişliğe neden olabilirler. Juvenil ossifiye fibroma (JOF) genelde çocuklarda ve ergenlerde görülen fibroosseöz lezyonlardan biridir. Agresiv karakterde ve yüksek nüks oranına sahiptir. Mandibulada yerleşim maksilladan daha fazladır ve histolojik olarak psammomatoid tipi trabeküler tipinden daha sık görülür. Tümörün yapısı nedeniyle tedavide genellikle çene rezeksiyonu tercih edilir. Bu olgu sunumunda 8 yaşındaki çocuk hastanın mandibulasında gelişen ve nadir görülen trabeküler tipte JOF ve tedavisi ele alınmaktadır.

Sekiz yaşındaki çocuğun alt çenesinde geniş bir kitle

Facial swellings in children may commonly arise from infection, jaw cysts or benign-malign tumors. Differential diagnosis should be handled considering onset of the symptoms, growth rate and child’s age. Fibro-osseous lesions are a group of lesions characterized by fibrosis and contain varying amounts of calcified tissue resembling bone, cement or both. Such lesions may cause enlargement and swelling in the jaws. Juvenile ossifying fibroma (JOF) is one of the fibro-osseous lesions usually seen in children and adolescents. It has an aggressive character with a high recurrence rate. Mandible is more affected than maxilla and psammomatoid type is more common than trabecular type histologically. Bone resection is generally preferred for the treatment due to nature of the tumor. Here we report a rare case of trabecular type JOF located in the mandible of an 8-year-old child treated by conservative surgery
