Undifferentiated carcinoma of the liver with osteoclast-like giant cells: a case report and literature review

Abstract

Abstract Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver. Osteoclast-like giant cells (OGCs) are relatively more common in pancreatic cancer, but extremely rare in HCC. Currently, there have been only a few reported cases of OGCs in HCC, and their presence indicates an aggressive clinical course. Here, we present a case of primary undifferentiated carcinoma of the liver with OGCs in a 49-year-old male patient, and through a literature review, we summarize 20 similar cases to further understand the diagnosis, treatment, and clinical course of this disease entity.
