[Smoke cloud pneumonia, a new atypical pneumonia in influenza diseases]

Since 1980 we have to reckon with a novel atypical pneumonia in influenzae. The clinical course of these fire-damp pneumonias is very discrete. In X-ray the changes of the lungs are uniform in density and considerably multiform in extent, in which cases the topographic-anatomic borderlines are not taken into consideration. They disappear within 6 to 8 days. There are no participations of pleura and hilus.
