title: Solitary primary peritoneal carcinoma arising from the omentum.
abstract: OBJECTIVE
  To report a case of isolated omental peritoneal carcinoma without peritoneal carcinomatosis.
  
  
  METHODS
  A 60-year-old female with abdominal distention was found to have a pelvic mass. Under the impression of ovarian cancer, laparotomy was performed only to show one isolated mass over omentum. Serial examination and pathology study including immunochemical staining indicated primary peritoneal serous carcinoma.
  
  
  CONCLUSIONS
  Isolated omental peritoneal carcinoma without peritoneal carcinomatosis and ascites is rare, and whether this represented a unique entity with different chemotherapy response and treatment outcome from the disseminated form of primary peritoneal carcinoma needs to be reviewed in the future.
