Abstract

A procedure of pathological analysis of laryngopharyngeal specimens by whole organ sections in the horizontal plane was developed and evaluated. The use of a fast decalcifying and fixative solution allowed both an easier sectioning of the whole organ and thin (5-6 μm) histological whole organ sections of laryngo pharyngectomy specimens. The complete procedure required 5 to 10 days for each case. A preliminary examination of 39 surgical laryngopharyngectomy specimens with laryngeal or hypopharyngeal carcinomas showed that most of the normal structures were histologically identifiable on whole organ horizontal histological sections. The data of the local neoplastic spread related to the main sites of origin were in accordance with the results obtained by other studies using whole organ sections in the coronal or vertical planes. In conclusion, with this procedure it is possible to obtain, in a reasonably short time, thin histological horizontal whole organ sections allowing an adequate and complete assessment of the microscopic characteristics of the tumor and of the tridimensional relationships of the neoplasm with the host organ; moreover, by this procedure pathological data may be compared with preoperative CT or MR scans in patients with laryngeal and hypopharyngeal carcinomas.
