Bone surface is an exceptional location for chondromyxoid fibroma. Only 14 cases of juxtacortical chondromyxoid fibroma have been reported to date and, to our knowledge, none of these cases are documented with imprint cytology. We report a case of periosteal chondromyxoid fibroma located in the distal tibial metaphysis of a 4-yr-old boy. The clinical diagnosis was metaphyseal fibrous defect. Cytologic examination revealed a mixoid matrix, with stellate and spindle-shaped cells seen singly, focus of chondroid material, and epithelioid cells. Multinucleate giant cells were not seen. The diagnosis of periosteal chondromyxoid fibroma can be made by fine-needle aspiration or imprint cytology with clinico-radiologic correlation.
骨表面是软骨黏液样纤维瘤的一个特殊发病部位。迄今为止，仅报道过14例皮质旁软骨黏液样纤维瘤病例，据我们所知，这些病例均未进行印片细胞学记录。我们报告1例位于4岁男孩胫骨干骺端远端的骨膜软骨黏液样纤维瘤。临床诊断为干骺端纤维性缺损。细胞学检查发现黏液样基质，可见单个的星状和梭形细胞、软骨样物质灶及上皮样细胞。未见多核巨细胞。骨膜软骨黏液样纤维瘤的诊断可通过细针穿刺抽吸或印片细胞学检查并结合临床放射学表现来做出。
