"...a marked lymphoid cell inflammatory reaction that was most extensive in the border zone area, where a gradual loss of normal acinar architecture was observed. These areas were defined as active border zones. The inflammatory cells had infiltrated from the active border zone into normal acinar tissue. Numerous intra-acinar lymphocytes were detected in both histologically normalacini and partly affected acini (Fig. 1 and 2, Study II). Occasionally, several """"separate"""" active border zone areas were found """"within the same"""" lobules, giving the appearance of piecemeal tissue destruction...
...Typical findings included numerous intra-acinar lymphocytes, piecemeal appearance of tissue destruction and the presence of large groups of lymphocytes resembling lymphoid follicle germinal centres..."
