Abstract

Aneurizmatska koštana cista čeljusti jest lezija slična benignom tumoru s ekspandirajućom osteolitičkom prirodom, koja se sastoji od krvlju ispunjenih prostora različitih veličina odijeljenih septima vezivnoga tkiva koji sadržavaju trabekule ili osteoid i osteoklastima slične divovske stanice. To je vrlo rijetka lezija koja čini otprilike 1,5% svih neodontogenih i neepitelnih cističnih tvorbi u čeljusti i izmeĎu 2 i 3 puta češće se pojavljuje u mandibuli nego u maksili. Najčešće se dijagnosticira u dvadesetim godinama života ili prije. Etiologija lezije nije potpuno razjašnjena. Klinički gledano, najčešće je riječ o oteklini. MeĎutim, klinička, radiološka i patohistološka slika variraju u ovisnosti o pojavnom obliku koji može biti solidan, vaskularan i mješovit. Diferencijalnodijagnostički, u obzir dolaze gigantocelularni tumor, solitarna koštana cista, ameloblastom, gigantocelularni granulom, miksom, fibrozna displazija, dezmoblastični fibrom, hemangiom i osteosarkom. Definitivna dijagnoza postavlja se nakon biopsije i patohistološke analize. Aneurizmatska koštane cista čeljusti liječi se kirurški. Lezija se uklanja u cijelosti kiretažom. Recidiv se nakon terapije ne očekuje, a, ako se pojavi, znak je nepotpuna uklanjanja lezije i neadekvatnog kirurškog zahvata. U težim slučajevima recidiviranja primjenjuje se i zahvat parcijalne resekcije.

Abstract (english)

Aneurysmal bone cyst of the jaw is similar to benign tumor lesions with a tendency of osteolytic expansion, consisting of blood-filled spaces of different sizes separated by fibrous septa containing trabeculae or osteoid and ostoclasst-type giant cells. This is a very rare lesion which accounts for approximately 1.5% of all non-odontogenic and non-epithelial cystic lesions in the jaw and is 2-3 times more common in the mandible than in the maxilla. Most often it is diagnosed in patients before the age of twenty. The lesion is of unknown etiology. A frequent clinical symptom is swelling of the jaw. However, clinical, radiological and histopathological symptomatology vary depending on the type of the lesion, which can be solid, vascular and mixed. Differential diagnosis includes giant cell tumor, solitary bone cyst, ameloblastoma, giant cell granuloma, myxoma, fibrous dysplasia, desmoplastic fibroma, hemangioma and osteosarcoma. A definitive diagnosis is given after biopsy and histopathological analysis. Aneurysmal bone cyst of the jaw is treated surgically. The lesion is removed entirely with curettage. Recurrence after treatment is not expected, but if it occurs, it is a sign of an incomplete removal of the lesion. In severe cases of relapse, block resection is indicated.
