Aneurysmal bone cyst of the jaws. Review of the literature and report of 2 cases.
ABSTRACT Strictly speaking, the aneurysmal bone cyst is not a true cyst. It is a lesion characterized by replacement of bone by fibro-osseous tissue containing blood-filled cavernous spaces. It is usually treated by surgical curettage, and access within the jaws may sometimes be difficult. We reviewed the world literature and found 63 cases of aneurysmal bone cysts involving the face, 22 reported in the maxilla, and 63 in the mandible. One was found in the zygomatic arch. Of the patients reported, 88% were younger than 30 years old; there was an equal sex distribution. Included in this report, are two cases of our own, one involving the maxilla and one the mandible.

ABSTRACT: An aneurysmal bone cyst of the maxilla is a nonneoplastic, uncommon, solitary bone lesion recognized by distinct radiographic and histopathological characteristics. It is described as a localized and quickly expandable benign tumor, which can reach a considerable size. It is characterized by the replacement of bone by spongy fibro-osseous tissue and a locally destructive and multicystic lesion filled with blood. It is attributed to a circulatory disturbance leading to locally increased venous pressure but with an unclear etiology. It takes place mainly in the long bones and in patients less than 20 years old, with no sex predilection. Its treatment is by surgical excision. An aneurysmal bone cyst in the facial bone is rare. The present case describes the lesion arising in the maxilla of a 14-year-old girl.Journal of Craniofacial Surgery 12/2004; 15(6):1029-33. · 0.69 Impact Factor

ABSTRACT: The case of a 6-year-old boy with a rapid growing mass in the right angle of the mandible that clinically and radiographically resembled a malignant lesion is presented. The biopsy specimen showed an aneurysmal bone cyst. The patient was treated surgically via extraoral approach including immediate mandibular reconstruction with with iliac crest bone. The literature is briefly reviewed.International Journal of Oral and Maxillofacial Surgery 09/2003; 32(4):419-22. · 1.52 Impact Factor

ABSTRACT: Cranial aneurysmal bone cyst (ABC) is a rare pathological finding that is usually diagnosed in young patients. It is defined as a benign lesion made up of intervillous spaces limited by connective bone tissue septa and osteoclast-type giant cells; these histological characteristics are common to extracranial ABC. Clinically, in most patients, they manifest as cranial tumours which may be painful and vary in size. About 100 cases of cranial ABC have been reported in the literature. We present a literature review of the cases of frontal ABC reported to date, including one that was recently treated in our own service. A 29-year-old female, with no history of traumatic brain injury, who was examined due to the presence of a fixed, painless frontal cranial lesion on the right-hand side. The results of a radiological study revealed the presence of a lytic cranial lesion with well-delimited edges and marginal sclerosis; peripheral and linear contrast enhancement was also observed in the magnetic resonance imaging of the brain. The patient was submitted to a surgical intervention and the entire lesion was removed. There were no incidents in the post-operative period and the definitive pathological diagnosis was cranial ABC. Cranial ABC is a pathological condition with well-defined histological and radiological characteristics, despite the fact that its aetiopathogenesis is still not fully understood. Complete excision of the tumour is considered to be the preferred treatment, which often leads to full recovery of the patient and also offers a good long-term prognosis.Revista de neurologia 03/2011; 52(6):349-54. · 1.18 Impact Factor
