嗜酸性肉芽肿是一种少见的类肿瘤样骨部疾病。可发生于除指掌骨以外的任何部位。其中半数以上见于颅骨,且以颞骨和额骨为多发。本文报告2例发生于颞骨。 本病病因不清。其学说有:①感染学说,认为感染因子改变了酶的代谢,致网状内皮系统增主。②代谢紊乱,因病变组织对放疗敏感而想到类脂质新陈代谢障碍引起异常类脂质贮藏于增生的网状内皮组织所致。③免疫功能失调,④某些病例继外伤后发病,⑤与潜在肿瘤伴发,但未发现遗传因素。组织病理为局
Eosinophilic granuloma is a rare tumor-like bone disease. It can occur anywhere except the metacarpal bone. More than half of them found in the skull, and the temporal bone and frontal multiple. This article reports 2 cases occurred in the temporal bone. The etiology of this disease is unclear. The doctrine: ① infection theory, that the infection factor has changed the metabolism of the enzyme, causing the reticuloendothelial system. ② metabolic disorders, due to lesions sensitive to radiotherapy and think of lipid metabolism disorders caused by abnormal lipid storage in hyperplasia of reticuloendothelial tissue caused. ③ immune dysfunction, ④ some cases following the onset of trauma, ⑤ associated with the potential tumor, but found no genetic factors.
