Pseudomyxoma peritonei due to adenocarcinoma of the lung: case report.
A rare case of pseudomyxoma peritonei whose primary site was presumed to be the lung is reported. A 76-year-old woman was admitted to Hospital presenting with progressive abdominal distention. She had been admitted twice, 2 and 1 year previously for the evaluation of high plasma carcinoembryonic antigen (CEA) level, of 11.6 ng/ml. Chest computed tomography (CT) scan and chest X-ray film on the third admission revealed a nodular lesion in the left lower lung field, and transbronchial lung biopsy (TBLB) revealed mucus-producing tall columnar epithelial carcinoma. Paracentesis revealed gelatinous ascitic fluid. At laparotomy, appendix and ovary were normal, and there were many small cystic tumors on the peritoneal surface and omentum. The patient died 2 years later, after repeated episodes of dynamic ileus. The lung and abdominal tumors gradually increased in size during the 2-year period, but she developed no respiratory symptoms. Based on both the clinical and pathophysiological findings, the final diagnosis made was pseudomyxoma peritonei whose origin was a lung adenocarcinoma.
