Organ: Lymph node
There is extreme(ly large) follicular hyperplasia, as seen by the abnormally large germinal centres. With higher magnification are small granulomas visible, so-called microgranulomas. In a small, triangular area on the right part of the slide can we see B-cells that resemble monocytes, so-called monocytoid B-cell hyperplasia.
