血管瘤是常见良性肿瘤之一,它好发于颜面部皮肤及口腔粘膜舌头等部位,亦可发生于肌间隙、骨骼系统。颌骨血管瘤一般分为周围型及中央型。周围型之血管瘤其血管来自骨膜,向骨表面侵蚀,促使骨皮质及骨松质吸收;中央型之颌骨血管瘤其血管从骨松质而来,向周围扩大,促便周围骨组织吸收。病理学上又把中央型之颔骨血管瘤分为毛细管型及海棉窦型。颌骨血管瘤以海绵型为主,镜下见有窦腔及完整之血管壁,扁平内皮细胞组成其内壁,与毛细管型之内壁由方形内皮细胞组成不同。临床诊断颌骨中央性血管瘤并非容易,因其早期可不显症状。肿瘤长大后,引起颌骨变形,例患者面部出现畸形,或压迫神经可引起疼痛,有时邻近之牙齿可出现松动,跳痛发麻等不适。同时,颌骨血管瘤偶尔因拔牙等手术流血不止而被怀疑作出诊断。皮肤粘膜之血管瘤多半在婴儿出生起就发生,初
Hemangioma is one of the most common benign tumors. It occurs in the facial skin and oral mucosa, tongue and other parts of the body, can also occur in the interosseous space, the skeletal system. Jaw hemangiomas are generally divided into peripheral and central type. Surrounding hemangioma its blood vessels from the periosteum, erosion to the surface of the bone, prompting the cortical and cancellous bone absorption; central jaw hemangioma vessels from the cancellous bone to the surrounding expanded to facilitate the absorption of bone tissue around . Pathologically, the central type of tarsal hemangioma is divided into capillary type and sponge sinus type. Maxillary hemangioma with sponge-based, see the sinus cavity and the entire wall of the blood vessels, flat endothelial cells composed of its inner wall, and capillary-type wall composed of square endothelial cells of different. Clinical diagnosis of central jaw hemangioma is not easy because of its early symptoms may not be obvious. Tumor grows, causing jaw deformation, patients with facial deformity, or nerve compression can cause pain, sometimes adjacent to the teeth may appear loose, tingling and other discomfort. At the same time, jaw hemangiomas are occasionally suspected of bleeding due to extractions such as tooth extraction. Mucosal hemangiomas of the skin occur mostly in infants since birth
