BRONCHO.ENG This application aims to compare the endoscopic aspects of bronchial and tracheal tumors with anatomopathological aspects. The endoscopic images were made by Jean-François Dumon, a pulmonologist specialized in thoracic endoscopy and in particular in interventional bronchoscopy. The anatomopathological images were made by Louise Garbe anatomopathologist. These two doctors worked in collaboration with the Hopital Universitaire Hopitaux de Marseille. Contact: firstname.lastname@example.org Any additional endoscopic or pathological image is welcome and will be added to the application by authoring its author.
