This study reports on an immunohistochemical examination of the tonsils. For this purpose 10 clinically healthy tonsils, 15 with acute tonsillitis, 40 with chronic cryptic tonsillitis and 16 hyperplastic tonsils were studied by means of the direct immunofluorescent technique. ⋯ In the extrafollicular area the fluorescent immunocytes were significantly increased. Although we did not notice differences in the density of IgA and IgM immunocytes between chronic cryptic tonsillitis and hyperplastic tonsils in the acute tonsillitis IgA immunocytes were found to be increased.
