This 9-year-old girl presented with a painful mass in the posterolateral aspect of her right knee. Excisional biopsy of the mass revealed a juxta-articular myxoma. The differential diagnosis for such an intra- or periarticular mass should include meniscal cyst, parameniscal cyst, ganglion cyst, juxta-articular myxoma, focal nodular PVNS, and desmoid tumor. Current imaging techniques do not allow differentiation between these benign lesions and low grade myxoid-containing sarcoma.
这名9岁女孩的右膝后外侧出现一个疼痛性肿块。对该肿块进行切除活检，结果显示为关节旁黏液瘤。对于这种关节内或关节周围肿块的鉴别诊断应包括半月板囊肿、半月板旁囊肿、腱鞘囊肿、关节旁黏液瘤、局灶性结节性色素沉着绒毛结节性滑膜炎和硬纤维瘤。目前的成像技术无法区分这些良性病变与含黏液样的低级别肉瘤。
