Unlike the B-lymphocytes, the T-lymphocytes,
specially revealed by the immunohistochemical reaction
to the CD45 antibody, appeared preponderantly
disposed at the lymphoid follicles periphery, into the
follicular cortical, but also into inter- and perifollicular
lymphocitary infiltrate (Figure 7).
Immunostainig with CD68 revealed the presence of
macrophages. In the cases studied by us we could
established the existence of an increased number of
CD68 positive cells of great sizes, which were present
relatively homogenous at the germinative clear center
level (Figures 8 and 9). The existence of macrophages at
that level pointed that following the lymphoblastic
proliferation intense processes, abnormal B-lymphocytes
could appear being recognized and taken away by
macrophages. An intense positive reaction to CD68 was
also observed in the superficial tonsil chorion;
immediately under the basal membrane of the covering
epithelium and even in the structure of the epithelium
(Figure 10). The macrophages presence at that level is
ordered by the existence of the pathogenic germs from
the tonsil surface and even from the superficial chorion.
CD68 positive cells were more numerous into the
amygdalian crypts epithelium, probably due to the
microorganisms and cell detritions accumulation and
remainings (Figure 11)
