Synopsis: Peritoneal pseudomyxoma is a condition where a mucin-producing tumor ruptures and the mucus accumulates in the abdominal cavity. Surgical tumor reduction is the most common treatment abroad, and some cases are treated using laparoscopy. No consensus on the optimal treatment has been established. An 81-year-old woman was accidentally detected with an intra-pelvic tumor using magnetic resonance imaging. The tumor included a solid part, along with a small amount of ascites. However, no enlarged lymph nodes or distant metastasis was noted. We performed staging laparoscopy because we couldn't completely deny the possibility of the ovarian borderline tumor before an operation. The intra-abdominal findings revealed peritoneal pseudomyxoma. No adnexal enlargement was observed, but the appendix was enlarged and had ruptured. Thus, we performed an additional appendectomy and mucus drainage. We continue to follow up the patient in collaboration with the department of gastrointestinal surgery, and no relapse has occurred so far. Various cases have been reported about the operation for peritoneal pseudomyxoma. This report suggest that laparoscopic operation enables us to perform less-invasive tumor reduction.
