Résumé

The x-ray microanalysis in the transmission electron microscope of different types of tumours (epithelial or not) confirms the increase of the sulphuric moiety: with the histochemical techniques of tannin-hiron chloride and lanthanum nitrate as ultrastructural tracers we can better attribute this result to proteic or glycoproteic substrata. In the uveal melanoma, in fact, the microanalytic result seems to be independent of the amount of pigment but is rather related to the proteic structure of the premelanosomes. In the lymphoplasmacytoid lymphoma, on the contrary, the same increased sulphuric moiety is referred to some glycoproteic substrata of the membrane.
