[The so-called chronic hyperplastic pharyngitis in childhood. A histological screening (author's transl)].

The clinical picture of chronic pharyngitis is well defined but insufficiently clarified as to its morphological nature. In our study of 12 children with chronic pharyngitis who underwent adeno-tonsillectomies small pieces of tissue of the posterior wall of the pharynx were microscopically examined. In most instances inflammatory infiltrations were absent. Present was a variably developed hyperplasia of the lymphatic tissues. In the more pronounced hyperplasias there was a lymphoepithelial disintegration that could account for the clinical manifestations and that perhaps could also be considered as a disposing factor for a bona fide pharyngitis. The micromorphological changes were divided into 4 stages.
