[Histopathological and immunological analysis of hyperplastic palatine tonsils and adenoids in children with coexisting atopic dermatitis].

Allergic sensitisation of the airways occurs in the mucosa of the shock organ, or in the lymphatic stations draining these structures. The lymphatic structure closest to the nasal mucosa in humans is the adenoid and tonsils. Research done in respect to Waldeyer's ring on people dealing at the same time with allergy, is seldom the subject of dissertation in polish as well as world wide medical literature. In the enclosed dissertation, writers present the results of histopathological and immunohistochemical analysis of hyperplastic tonsils and adenoid, taken from children with coexisting atopy. The authors describe an immunohistochemical analyses of the hyperplastic human palatine tonsil. They present the expression of antigen CD3, CD20, CD45, CD68, EMA, SMA, Vimentin, Desmin, S-100, von Willebrand Factor, p35, Bcl-2, melanin, cytokeratin, estrogen receptor, progesteron receptor, kolagen IV and NSE in every region of pallatine tonsil. It is worthwhile to remark, that many of these cases, the presence of eosinophilia and subepithelial oedema was observed. Our immunohistochemical findings support the hypothesis that allergic sensitization takes place in the adenoid and tonsils. Furthermore, this study confirms that dendritic cells ad macrophages are involved and important in allergic disease.
