Ultrastructural morphometric studies on benign and malignant lung tumours.

Premalignant and malignant lesions from human lung tumours have been investigated by ultrastructural stereological methods and compared to normal bronchial tissue. It was possible to develop characteristic quantitative ultrastructural criteria for the different lesions. These criteria are the basic of a data bank system. After verification by further investigations they may be applicable to the development of a diagnosis supporting system.
