Hemangioma of the mandible in a 12-year-old boy

@#Intraosseous hemangioma is a benign, rare neoplasm that accounts to 0.5 - 1% of all benign tumors of bones.1, 2 While most hemangiomas arise from soft tissues, it is uncommon for it to arise from bones.2 The most common sites of growth are in the vertebral body and the calvarium with frontal bone making up approximately 45% of calvarial cases.2,3 However, they are also encountered in the head and neck with sites such as the skull (53%), mandible (10.7%), nasal bones (9%), and cervical spine (6%).4 In the mandible, the body is mostly affected and 65% are found in the molar and premolar region.1 They are more common in adult females with peaks at the second and fifth decades of life.1-3 Hemangioma of the mandible is difficult to diagnose due to its nonspecific clinical presentation and radiographic features. It mimics various mass lesions in the mandible such as giant cell granuloma, fibrous dysplasia, multiple myeloma, osteosarcoma, ameloblastoma and keratocysts. Therefore, a comprehensive history taking and physical examination plus examination of the imaging studies available and tissue biopsy all play important roles in arriving at the final diagnosis.5 We present the case of an aggressive mandibular hemangioma in a young boy and our management involving a failed fibular free flap reconstruction.

Hemangioma intraóseo de la mandíbula: reporte de un caso clínico / Intraosseous hemangioma of the mandible: report of a clinical case

El hemangioma intramandibular es una neoformación benigna que resulta de la proliferación anormal de vasos sanguíneos, de origen desconocido. Estos tumores, por lo general, son hallazgos radiológicos y se caracterizan por ser asintomáticos y/o presentar movilidad de los dientes afectados, asimetría facial, parestesias y dolor, entre otros síntomas. Después de las vértebras y el cráneo, la mandíbula esel sitio más frecuentemente afectado, sobre todo en su parte posterior.El propósito de este trabajo es presentar un caso clínico de esta enfermedadpoco habitual.

Intraosseous hemangioma of the mandible is a benign neoplasm that originates from the abnormal proliferation of blood vessels, the cause of which is unknown. In general, these tumors are detected by means of X-ray and are characterized as asymptomatic or presenting mobility in the affected teeth, facial asymmetry, paresthesia and pain, among other symptoms. After the vertebrae and skull, the most frequently affected site is the jaw, particularly the posterior part. The purpose of this paper is to present a clinical case of this rare disease.

Intraosseous Hemangioma of the Zygoma and Its Management

PURPOSE: Intraosseous hemangiomas are rare and account for fewer than 1% of all bone tumors. The site that is most commonly involved are the vertebral column and the skull. Within the facial skeleton, hemangiomas can occur in the mandible, maxilla, the nasal bones, and rarely the zygoma. METHODS: We report a case of an intraosseous hemangioma of the zygoma in a 49-year-old male. The patient had a slow growing hard mass in the left zygoma, which had been present for 8 years. Other than the cosmetic deformity, the patient experienced no pain and did not have any problem. He had no history of trauma in that area and no ocular symptoms. Preoperative computed tomography showed a trabeculated mass arising from the body of the left zygoma. The mass was surgically removed without having to reconstruct the bone defect by spairing the inner cortex. RESULTS: Histopatholgical examination indicated a cavernous hemangioma. After 4 months of follow up, no functional and cosmetic impairment was identified. The patient was satisfied with the result. CONCLUSION: An intraosseous hemangioma of the zygoma can be treated with total surgical excision with preservation of the inner cortex, thus eliminating the need for reconstruction of bone defect.
