title: Pregnancy complicated by acute pulmonary lymphangitic adenomatosis, metastasis and disseminated intravascular coagulation. A case report.
abstract: BACKGROUND
  The association of pregnancy and cancer is a rare event, occurring in less than 1 case per 5,000 pregnancies, and is a cause of maternal mortality in about 5% of cases.
  
  
  METHODS
  A 33-year-old, Japanese woman presented at the end of pregnancy with clinical manifestations of pneumonia and developed fatal disseminated intravascular coagulation in the postpartum period. The pathologic findings suggested the existence of a primary cancer in the gastrointestinal tract with pulmonary and placental metastases.
  
  
  CONCLUSIONS
  The biologic course of malignancies in pregnancy is complex. In gastrointestinal cancer, normal pregnancy symptoms can mask and delay the diagnosis. As in this patient, very rare presentations are possible.
