title: Aspiration biopsy of osseous metastasis of occult hepatocellular carcinoma: Case report, literature review, and differential diagnosis.
abstract: Fine-needle aspiration (FNA) cytology is a reliable technique for rapid diagnosis in virtually every organ of the body, including bone lesions. We report on the FNA findings in a 61-yr-old male of an osteolytic sacral lesion, which determined the diagnosis of an unsuspected metastatic hepatocellular carcinoma. In this case, the diagnosis was confirmed by FNA biopsy without resorting to surgical biopsy.
