[A Case of Appendiceal Pseudomyxoma Peritonei Diagnosed by Inguinal Hernia and Treated with Multidisciplinary Treatment].

Pseudomyxoma peritonei (PMP)is a clinical condition caused by ruptured mucinous tumors like appendix and ovaries, and large amounts of mucus fill the abdominal cavity. We experienced a case of PMP presented with an inguinal hernia. A 62-year-old man complained of a bulge in the left inguinal region. The results of the test was PMP caused by ruptured appendiceal myxoma. After intraperitoneal chemotherapy, we performed surgery. We performed right hemicolectomy, low anterior resection, peritoneum excision of the pelvic space, right diaphragm resection, omentectomy, cholecystectomy and splenectomy. Finally, hyperthermia chemotherapy was performed. Microscopic findings showed PMP caused by low-grade appendiceal mucinous neoplasm. We report this case with some bibliographic consideration.
