[Classification of the lung conditions in cases of perinatal death]

Comparability of morphological lung findings depends on the greatest possible consistency in assessment and verbal definition. It is for that purpose that a classification of perinatal pulmonary morphology is proposed, based on latest knowledge in foetal and paediatric pathology and established with due consideration of findings from clinical and physiological research as well as of the author's own experience. The findings have been subdivided into five main groups, each of them with several sub-groups, and have been pathomorphologically so characterised that the new classification can be easily used in prosector practice.
