  • Title: Cytologic, ultrastructural and immunologic features of intracytoplasmic hyaline bodies in fine needle aspirates of hepatocellular carcinoma.
    Author: MacDonald K, Bedard YC.
    Journal: Acta Cytol; 1990; 34(2):197-200. PubMed ID: 2157323.
    Abstract:
    Intracytoplasmic hyaline bodies in malignant cells from an aspirate of a liver mass are suggestive of hepatocellular carcinoma. Such inclusions were studied by light and electron microscopy and by immunocytochemistry in fine needle aspirates from five cases of hepatocellular carcinoma. Seen by light microscopy, the inclusions were round or ovoid and were surrounded by a prominent halo. By both light and electron microscopic immunocytochemistry, the hyaline bodies showed negative staining for alpha-fetoprotein, alpha-1-antitrypsin and cytokeratin. Ultrastructurally, they were not membrane bound and were composed of filamentous, finely granular material, resembling the early stages of Mallory bodies.
