Cytoplasmic fusions between liver parenchymal cells and infiltrating cells in chronic aggressive hepatitis

Lymphocytes and plasma cells have been demonstrated in the peripheral zones of lobules in liver biopsies from patients suffering from chronic aggressive hepatitis. In the region of contact between lymphocytes and parenchymal cells, the cell membranes are frequently not demonstrable so that an impression is created of cytoplasmic fusion. However, when the goniometer is used, the cell membranes in this region can still be demonstrated at a certain tilt angle. It can therefore be concluded that the presumed cytoplasmic fusions are frequently the result of superposition effects in projection.
