[Histochemical study with lectins in nasal polyposis].

Histochemical study done with lectins is useful in order to differentiate between several carbohydrates from glycoproteins and glycolipides present in cellular membranes. Plasma cells and eosinophils are very frequent findings in nose mucous of patients with nasal polyposis. Histochemistry with lectins of plasma cells show a reactivity of the cellular cytoplasma to ConA while the external cellular membrane stains with PNA.
