Soleus Muscle Single Metastasis from Hepatocellular Carcinoma

Area of Science:

• Hepatobiliary cancers
• Oncology
• Medical imaging

Background:

• Hepatocellular carcinoma (HCC) is an aggressive primary liver cancer.
• Extrahepatic metastases (spread outside the liver) occur in approximately 15% of HCC cases.
• Skeletal muscle metastasis from HCC is exceptionally rare.

Discussion:

• This report details a unique case of HCC metastasis to the soleus muscle in a 76-year-old male.
• The patient presented with a calf mass, diagnosed via MRI and biopsy.
• Limited treatment options and poor prognosis underscore the rarity and challenge of managing such cases.

Key Insights:

• Skeletal muscle involvement represents an extremely rare site for HCC metastasis.
• Diagnosis involved characteristic imaging findings and histopathological confirmation.
• The case emphasizes the aggressive behavior of HCC with extrahepatic spread.

Outlook:

• Further research is needed to understand the mechanisms of rare HCC metastases.
• Early detection of extrahepatic lesions may improve patient outcomes.
• Developing targeted therapeutic strategies for rare metastatic sites is essential.
