Pulmonary tumor thrombotic microangiopathy caused by gastric cancer

Hiroko Kuwabara et al. Ann Thorac Med. 2012 Jul.

Abstract

Pulmonary tumor thrombotic microangiopathy (PTTM) is a fatal cancer-related pulmonary complication with rapidly progressing dyspnea, and occasionally induces sudden death. Here, we describe a postmortem-diagnosed PTTM case caused by gastric cancer, with the complaint of progressing dyspnea for 5 days.He did not have any abdominal symptoms or cancer history. PTTM should be considered in patients with rapidly worsening respiratory conditions, even if there is no cancer history.

Keywords: Dyspnea; PTTM; gastric cancer.
