[Migratory and recurrent pneumonias (authors transl)].

Pneumonia migrans and pneumonia recurrens are rarely seen non typic developments of pneumonia mostly due to viral infections. We observed the course of a pneumonia migrans on a 38-year old woman with development of new pneumonic infiltrations in other lung segments before definite healing. A 34-year old gravida developed a pneumonia of the right upper lobe immediately after total healing of the lower lobe of the same lung. The atypic course of the disease is looked for in an insufficient local immunity.
