title: Pulmonary metastases in pseudomyxoma peritonei syndrome.
abstract: BACKGROUND
  Pseudomyxoma peritonei (PMP) is a rare disease arising from a mucinous cystadenoma of appendiceal origin. The syndrome has been characterized by progressive growth of mucinous tumors, tense mucinous ascites, and ultimately death. Abdominal and pelvic recurrence after resection of intraperitoneal disease occurs in all patients unless adjunctive measures are taken. Local spread of PMP by direct extension to the pleural or pericardial space is uncommon but has been reported in the literature. Here we report development of pulmonary parenchymal metastases after treatment for PMP.
  
  
  METHODS
  The charts of 3 patients were retrospectively reviewed for the presentation and management of metastatic PMP.
  
  
  RESULTS
  Three patients underwent resection for pulmonary parenchymal metastases of PMP. All patients recovered uneventfully. The continue to do well after 2 to 8 years of follow-up.
  
  
  CONCLUSIONS
  Pulmonary metastasectomy for PMP is safe and effective after treatment of intraperitoneal disease.
