Variable histopathological features of 6 cases of aneurysmal bone cysts developed in the jaws: review of the literature.

OBJECTIVES

The aim of this study was to evaluate the results of treatment of 6 patients with ABC who were treated in our clinic.

MATERIAL AND

METHODS

A group of 6 patients with ABC were treated in the clinic of Oral and Maxillofacial Surgery of the "G. Papanikolaou" hospital in Thessaloniki. The age of the patients ranged from 7 to 35 years. Four patients were female and 2 patients were male. Three lesions located in the maxilla-maxillary sinus and 3 lesions in the mandible. All the patients were treated by surgery (excision via curettage or radical resection). The final histopathologic diagnosis for one lesion was "solid" type of ABC and for another one it was ABC in association with an ossifying fibroma.

RESULTS

The mean follow-up range was 2-17 years. All the patients were free of the disease without functional problems.

CONCLUSIONS

ABC is a rare bony lesion characterized by variable clinical and radiographic features. The incisional biopsy preoperatively is important for the diagnosis before the surgical treatment. The histopathological examination of the whole lesion is determinative for the existence of associated pathological lesions. Regular follow-up is important to detect any recurrence of the lesion.
