摘要
目的 提高对骨膜骨肉瘤 (POOS)临床病理特征的认识 ,减少误诊。方法 用X线摄片及组织石蜡切片HE染色对 4例POOS进行临床病理分析。结果 4例POOSX线示骨皮质表面阴影 ,不侵犯骨髓腔。组织学上由大量分叶状软骨构成 ,其间有增生的异型梭形细胞直接形成瘤骨。结论 POOS是位于长骨皮质表面的恶性骨肿瘤。需与骨膜软骨肉瘤、骨表面高度恶性骨肉瘤、骨旁骨肉瘤。
ObjectiveTo increase one's knowledge of the clinic opa thological characteristics of periosteal osteosarcoma and to decrease the rate o f misdiagnosis MethodsX-ray film and routine pathological methods were utilized to analyse 4 cases of periosteal osteosarcoma ResultsRadiographically, all the 4 cases of periosteal osteosarcoma were located sup erficially in the cortex of the bone and the medullary cavity was uninvoloved The histological appearance of the tumor was predominantly one of low or medium -grade malignant chondrosarcoma, with small islands of anaplastic spindle cell s that produced malignant osteoid ConclusionsPeriosteal osteosa rcoma arises from the surfaces of long bones and should be differentiated from periosteal chondrosarcoma, high grade surface osteosarcoma, parosteal osteosarcoma, chondroblastic osteogenic sarcoma and periosteal chondroma
