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: Aneurysmal bone cysts, benign lesions of bone tissue, are composed of sinusoidal and vascular spaces filled with blood and surrounded by fibrous tissue septa. They are uncommon, occurring usually in the long bones and spine, and only very rarely in the jaw, where approximately 160 cases have been reported, of which two thirds were located in the mandible and one third in the maxilla. We report two rare cases of aneurysmal bone cyst occurring in the mandible. A literature survey revealed 34 cases of this disease in the jawbone in Japan. An analysis of aneurysmal bone cysts of the jaw was performed in 36 cases, including the present ones. The mandible was affected in 28 cases (78%) and the maxilla in 8 (22%). Aneurysmal bone cyst was observed to occur most frequently between the mandibular body and the ramus. Patient age ranged from 6 to 87 years, with a mean age of 27.7 years. Patients under 30 years of age occupied 60% of the total. Treatment options suggested in the literature include percutaneous sclerotherapy, therapeutic embolization, curettage, block resection and reconstruction, radiotherapy, and systemic calcitonin therapy. The extent of surgery will depend on the size and position of the lesion, ranging from simple curettage to extended resection.Journal of Oral and Maxillofacial Surgery, Medicine, and Pathology. 04/2013; 25(2):129–133.

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

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
