Carcinoma cuniculatum of the larynx must be considered as a distinct 'clinicopathological entity' and close cooperation between the clinician and the pathologist is essential for the correct diagnosis of these tumour as regards to the correct classification and therapy.

Two vitreous samples, 0.9 Z n (PO3)2 • 0.1 Eu(PO3)3 and pure zinc metaphosphate, were examined by X-ray diffraction to determine the local environment of the Eu3+ ion. Using a difference procedure involving the radial functions of the two glasses, the results indicate that the rare-earth ion is surrounded on average by a polyhedron of about 7.4 oxygens at 2.36 A and about 1.6 oxygens at 2.68 Å. A possible different coordination of the zinc ion in the two samples, suggested by the experimental findings, is discussed.
