title: [Papillomas of the mucous membranes of the larynx and pharynx. Relations between enzyme histochemistry and histological classification (author's transl)].
abstract: If there is a histochemical demonstration of acid phosphatase and lactat dehydrogenase with cryostat-microtom-sections of 30 papillomas of the mucous membran of larynx, pharynx and cavum oris you often can find strong activities in tissue with frequent atypical epithelial cells. Intensive appearances after reactions of NADH-tetrazolium-reduktase are correlated with strong hyperplasies and proliferations of the epithelial tissue. Cell groups in the stroma, which are immuncompetantly are showing an moderate activities of acid and alkaline phosphatase, esterase and NADH-tetrazoliumreduktase.
