嗜酸性肉芽肿是多发于儿童和青年,是一种网状内皮细胞增生症。病变局限于骨骼,为孤立的或多发的溶骨性损害,以颅骨、肋骨、长骨较多见。一般预后良好。笔者近两年来曾遇二例乳突骨嗜酸性肉芽肿,由于病变部位的特殊性,且发病迅速,骨组织破坏严重,肉芽组织多,时有血性脓液等临床表现,诊断上有一定困难,现报告于后。 Eosinophilic granulomas are common in children and young people, is a reticuloendothelial disease. Lesions confined to the bones, isolated or multiple osteolytic lesions to the skull, ribs, long bones more common. The general prognosis is good. I have encountered in the past two years, two cases of mastoid eosinophilic granuloma, due to the particularity of the lesion, and the rapid onset of serious damage to bone tissue, granulation tissue, sometimes bloody pus and other clinical manifestations, there are some difficulties in the diagnosis Now reported later.
