软骨粘液样纤维瘤

Chondromyxoid Fibroma

作者研究２７例软骨粘液样纤维瘤，其病变最常累及年青人的长骨。Ｘ线片上，骨病变呈境界清楚的良性形态。组织学上，呈现假小叶状肿瘤，具有粘液样和软骨样区。周边部瘤细胞有异型性、多形性、双核，但分裂象罕见。本文讨论了软骨粘液样纤维瘤的发生率、诊断、鉴别诊断和治疗。

A series of 27 cases of chondromyxoid fibrome(CMF)is reported.Long bone tumorswere common in young patients. Radiographically,bone lesions were well defined and benign appear-ance. The histoiogic picture was of pseudolobulated tumor with myxoid and chondroid regions. Tumorcells at peripheral were atyplcal,pleomorphic,and binucleate, but rarely continued mitoses. The inci-dencef,diagnosis,differential diagnosis and treatment of chondromyxoid fibroma are discussed.
