“Endothelioma” of the Pleura

摘要: INTRODUCTION Perhaps as much because of the confusing character clinical phenomena, rather striking appearances revealed after death, supposed primary malignant tumors pleurae have consistently appealed to medical writers worthy study and report. Further stimulus investigation this somewhat peculiar group has been furnished by clearly apparent wide diversity concepts derivation, or genetic significance, these tumors. Rarely students any other subject in science propounded such a bewildering array contradictory theories, often without due allowance either for limits our knowledge demands good logic. Hence it must be granted that, while discussion may certain practical applications, far more important considerations are wholly theoretical. So widely related, however, theoretical relationships, so fundamentally conclusions which reached, that review attempts clarify harmonize full justification effort. It is quite true efforts usually result formation new group, classification, an already involved nomenclature only further obscured. The less hesitation therefore accompanies presentation my study, not no name proposed, but, reasons seem sufficient, I am strongly suggesting dropping from list term never given real service nor ever satisfactorily employed. hope, then, conceptions with regard classifications simplified, complicated, necessary empiricism earlier years completely clarified generalizations appear justifiable.
