Extraskeletal myxoid chondrosarcoma (EMC) is a relatively rare but well-defined neoplasm. This report describes two patients, one with EMC of the buttock and one with EMC of the knee. The two cases presented with large lobed masses and long T1 and T2 signaling identified by magnetic resonance imaging (MRI). An enhanced MRI scan demonstrated enhancement of the tumors. The tumors were composed of strands or cords of oval and spindle cells embedded in abundant myxoid stroma. Pathology results confirmed EMC.
骨外黏液样软骨肉瘤（EMC）是一种相对罕见但定义明确的肿瘤。本报告描述了两名患者，一名患有臀部EMC，另一名患有膝部EMC。这两例病例均表现为大的分叶状肿块，磁共振成像（MRI）显示为长T1和T2信号。MRI增强扫描显示肿瘤有强化。肿瘤由嵌入丰富黏液样基质中的椭圆形和梭形细胞条索或索状结构组成。病理结果证实为EMC。
