嗜伊红肉芽肿一般认为是一种良性的网状内皮细胞增生,表现为孤立的溶骨性病变。原发于肺,皮肤,胃及脊髓的嗜伊红肉芽肿在组织学上不易相互区分。此类疾病的临床表现差异很大,从一种可以手术切除与放射治疗,不影响到生命的嗜伊红肉芽肿局限型到一种可以致命的、对化疗仅有姑息的疗效的全身型均可出现。颞叶孤立性的嗜伊红肉芽肿过去未见有报告,以往的报导都位于丘脑下部 Eosinophilic granuloma is generally considered to be a benign reticuloendotheliosis with an isolated osteolytic lesion. Erythroblastic granuloma, which originates in the lungs, skin, stomach, and spinal cord, is not readily distinguished from each other histologically. The clinical manifestations of these diseases vary widely, ranging from a type that can be surgically treated and treated with radiation, that does not affect life-threatening eosinophilic granuloma, to a systemic type that can be fatal and that is only palliative to chemotherapy. Can appear. Isolation of eosinophilic granuloma in temporal lobe has not been reported in the past. Previous reports have been located in the hypothalamus.
