    Heterogeneity in a colonic carcinoid tumor (1987)
    Springer
    Virchows Archiv 410 (1987), S. 93-96 
    Details
    ISSN: 1432-2307
    Keywords: Heterogeneity ; Ultrastructure ; Colonic carcinoid
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary This report describes a colonic carcinoid tumor in which three, and possibly four, distinct cell types are distinguishable on the basis of their ultrastructure and granule morphology. These cell types closely resemble the normal endocrine cells of the large bowel, both in appearances and in relative frequency. The mixed composition of this tumor may have arisen either by parallel differentiation of distinct cell types, or by sequential maturation of one cell type.

    Mechanisms of invasion and lymphatic penetration in human colorectal cancer (1989)
    Springer
    Clinical & experimental metastasis 7 (1989), S. 507-516 
    Details
    ISSN: 1573-7276
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The invasive areas in 24 unselected human colorectal cancers were examined by light and electron microscopy and it was shown that the invasive process involves tubes of cells rather than single cells, that degenerative changes take place in specialized cells ahead of the invasive cancer cells and that the endothelium of the lymphatic vessels disintegrates, leaving gaps in the endothelial lining.
