BACKGROUND
Extraskeletal myxoid chondrosarcoma is a rare soft tissue tumor of the extremities. Since it usually lacks obvious chondroid differentiation on light microscopy, it needs to be distinguished from other myxoid soft tissue sarcomas.
CASE REPORT
The diagnosis of extraskeletal myxoid chondrosarcoma was made on fine needle aspiration in a patient with a swelling in the right calf. Cellular myxoid fragments having round to oval cells with grooved nuclei arranged in a cordlike pattern suggested chondroid differentiation. The diagnosis was confirmed by histopathology.
CONCLUSION
Fine needle aspiration cytology can be diagnostic of extraskeletal myxoid chondrosarcoma even in the absence of obvious chondroid differentiation.
背景
骨外黏液样软骨肉瘤是一种罕见的四肢软组织肿瘤。由于其在光镜下通常缺乏明显的软骨样分化，因此需要与其他黏液样软组织肉瘤相鉴别。
病例报告
一名右小腿肿胀的患者经细针穿刺抽吸确诊为骨外黏液样软骨肉瘤。细胞黏液样碎片中可见圆形至椭圆形细胞，核有沟，呈索状排列，提示软骨样分化。组织病理学证实了诊断。
结论
即使在缺乏明显软骨样分化的情况下，细针穿刺抽吸细胞学检查也可诊断骨外黏液样软骨肉瘤。
