Skeletal muscle metastases of hepatocellular carcinoma: A case report and literature review

Figure 1 Imaging examinations. A: Two-dimensional ultrasound images show mixed echoes in the muscularis of the right thigh with unclear boundaries; B: Power Doppler activity revealed significantly increased flow within the tumor.

Figure 2 Magnetic resonance imaging. A: Coronal scan of the arrow points iso-signal of the tumor intensity on T1-weighted images; B: The arrow indicates high-signal intensity on T2-weighted images compared with the surrounding muscle.

Figure 3 Pathological analysis. A: Immunohistochemical staining examination of metastatic hepatic carcinoma hepatocyte paraffine 1 (Stain, 400 ×); B: Pathological examination of the tumor in the right thigh (Hematoxylin stain, 200 ×); C: Immunohistochemical staining examination of the tumor in the right thigh of metastatic hepatic carcinoma glypican-3 (Stain, 400 ×).
