Abstract

A 41-year-old male patient refers to a painful tumor on the lateral side of the right leg. Ultrasonography visualized a predominantly hypoechoic well-delineated large heterogeneous mass in the subcutaneous tissue, showing an internal hyperechoic area. Magnetic resonance imaging (MRI) demonstrated an oval and lobulated tumor with well-defined margins at the anterolateral part of the leg, with contrast enhancement. The anatomopathological evaluation revealed a neoplasm with an extensive chondromyxoid matrix. The immunohistochemical study demonstrated positive vimentin (V9 clone), positive S-100 protein and negative desmin (D33 clone), smooth muscle actin (1A4), CD68 (KP1 clone) and caldesmon. The set of findings is compatible with myxoid liposarcoma.
腿部黏液样脂肪肉瘤:影像与解剖病理检查的相关性
一位41岁的男性患者指的是右腿外侧疼痛的肿瘤。超声检查可见皮下组织内明显低回声、轮廓清晰的非均匀大肿块,显示内部高回声区。磁共振成像(MRI)显示一个椭圆形和分叶状肿瘤,在腿的前外侧有明确的边界,对比度增强。解剖病理检查显示肿瘤有广泛的软骨粘液样基质。免疫组化研究显示V9克隆的vimentin阳性,D33克隆的S-100蛋白阳性,desmin阴性,1A4平滑肌肌动蛋白阳性,KP1克隆的CD68阳性,caldesmon阴性。这组结果与黏液样脂肪肉瘤一致。
