[Morphological typing of respiratory tract tumors].
A group of 224 tumours of the respiratory tract was used to present experience with the standard histological classification, as proposed by WHO--incl. the revised version of pulmonary tumour classification which is under preparation. Electron microscopic facts from the authors' own material as well as from recent literature served in particular as a stimulus for the critical evaluation of some details of the standard classification. It served also as the basis for recommendations for rational modifications for its use in particular in Czech and Slovak speaking areas: 1. Prefer in respiratory pathways the term papilloma from respiratory epithelium to "transient" papilloma and not differentiate exophytic and inverted forms. 2. Respect the differentiation of bronchial adenomas and carcinoids, but identify atypical carcinoids with small-cell (oat-cell) carcinomas. 3. As to other carcinomas of the respiratory pathways to differentiate only between squamous carcinomas (spindle-cell and verrucal), glandular (in addition to adenoid cystic and mucoepidermoid) and undifferentiated. 4. In the section of pulmonary carcinomas to abandon completely large-cell carcinomas and to describe tumours which cannot be included in other groups as undifferentiated carcinomas. 5. Avoid in the other respect satisfactory classification pattern of pulmonary carcinomas subvariants (in particular in the group of glandular carcinomas) and include exceptional units in the group "others". 6. Arrange the group of malignant lymphomas according to the extrapulmonary classification pattern and include there from the group of tumourous lesions so-called lymphoproliferative processes, eosinophil granuloma and gangrenescent granuloma. 7. Use consistent with the nomenclature in the sphere of the nervous system the term olfactory neuroblastoma and omit its rare sub-variants.
