The histopathological analysis of pharyngeal tonsils in children with coexisting allergy of upper respiratory tract

Introduction. Adenoidectomy is the most frequent surgical procedure performed in small children, but the reasons of adenoid hypertrophy are not completely explained. Some authors report that in some children, allergy can be a risk factor for adenoid hypertrophy.
Aim of the study. The aim of this study was the histopathological analysis of the adenoid in children with coexisting allergy.
Material and methods. Two separate groups of children were examined. The study group consisted of 86 children between 4 and 11 years old, hypersensitive to house dust mites or to tree pollens, suffering from seasonal allergic rhinitis. The control group consisted of 72 non-atopic children (negative interview and skin-prick tests) at a similar age. The histopathological analysis of the adenoid was made in both groups.
Results. In the adenoidal tissue from children with seasonal allergic rhinitis operated during the pollination season, the signs of allergic inflammation (i.e. tissue eosinophilia, subepithelial edema, elevated number of macrophages, increase in the number and size of the follicles) was statistically more frequent than in children with perennial allergic rhinitis and in children with seasonal allergic rhinitis operated after the pollination season. In the latter case, there was no difference between the allergic group and the controls.
Conclusion. Our histopathological findings support the hypothesis that during the active period of allergic rhinitis in children, the allergic inflammation affects also the adenoid tissue.
