title: Two independent primary mucinous tumors involving the appendix and ovary accompanied with acellular pseudomyxoma peritonei.
abstract: We report a case of a 30-year-old woman who had complained of lower abdominal distension. She was noted to have a history of primary mucinous tumor of the left ovary (13.2 × 9.9 × 10.4 cm) that was removed surgically. Two years later she developed the same tumor on her left ovary (8.7 × 6.0 × 6.9 cm) and also had appendiceal mucinous tumor accompanied with acellular PMP. Final pathology revealed two truly independent primary mucinous tumors involving the appendix and ovary accompanied with acellular PMP. We recommend a minimum follow-up of 5 years for the patient to detect any development of mucinous tumors and the acellular pseudomyxoma peritonei.
