本文总结了我院近8年来经病理组织学确诊的恶性纤维组织细胞瘤11例。男性6例,女性5例;1例小于20岁,10例大于40岁;上颌骨6例、下颌骨4例、额部软组织1例。其X线表现多样,多数病例颌骨骨质破坏呈恶性征,以溶骨性破坏为主,无碎骨、死骨或肿瘤骨形成,无骨膜增生反应,病程进展迅速,累及范围广泛,常穿破骨皮质,早期形成外侵软组织肿块,不易与颌骨癌和溶骨型骨肉瘤区别。少数病例应与骨髓炎、纤维骨瘤及颌骨囊肿等鉴别。
This article summarized 11 cases of malignant fibrous histiocytoma confirmed by histopathology in our hospital in the past 8 years. There were 6 males and 5 females; 1 was less than 20 years old and 10 was older than 40; 6 cases of maxilla, 4 cases of mandible, and 1 case of frontal soft tissue. The X-ray findings are diverse. In most cases, the bone destruction of the jaws is a malignant sign, mainly osteolytic destruction, no bone fragmentation, sequestrum or tumor bone formation, no periosteal hyperplasia reaction, rapid disease progression, extensive range of involvement, often Perforating the cortical bone, early formation of external infiltrative tissue masses is not easy to distinguish from jaw bone cancer and osteolytic osteosarcoma. A few cases should be differentiated from osteomyelitis, fibrosarcoma, and jaw cysts.
