title: Low pleural fluid amylase associated with spontaneous rupture of the esophagus.
abstract: All previously reported determinations of pleural fluid amylase in Boerhaave's syndrome have demonstrated elevated values. We treated a patient with Sjögen's syndrome who had a low pleural fluid amylase level and the concomitant unusual finding of leakage of esophageal contents into the right pleural space.
