CASE HISTORY

This man had had a peptic ulcer for about 15 years and developed pyloric stenosis. In October 1936 he had a gastro- enterostomy performed. He remained well for some days and then developed a bronchopneumonia that went on to abscess formation. At this time sulphapyridine was not yet available.

PATHOLOGY

The specimen consists of the posterior half of the right lung. The upper lobe is oedematous, the lower lobe shows pneumonia with abscess formation. In the upper part of the lower lobe the pneumonia is confluent and has caused practically complete consolidation. In this area there are a number of irregular abscesses with ragged walls and with no signs of any reaction around them, the abscess walls simply fading off into the surrounding consolidated lung. In the lower zone the lung shows oedema alternating with patchy areas of bronchopneumonia. Several of the consolidated areas show commencing abscess formation similar to, but less extensive than, that in the upper part of the lobe. The pleura shows some old fibrous adhesions but surprisingly little recent reaction.
