A Case of Malignant Peritoneal Mesothelioma in an Incarcerated Inguinal Hernia

Abstract

We report the case of a 75-year-old man who was brought to our emergency room for a right incarcerated inguinal hernia. An emergency surgery revealed a firm mass and hypertrophy in the hernia sac and multiple nodules in the peritoneum. Malignant peritoneal mesothelioma was the final histological diagnosis. He chose not to receive chemotherapy. He did not undergo medical intervention for 5 months, although the disease gradually progressed, leading to worsening symptoms, such as abdominal distension and dullness. The patient finally chose to be treated with chemotherapy containing paclitaxel, which was administered weekly for 3 consecutive weeks followed by a one-week rest. After one course of administration, he refused to continue outpatient chemotherapy and chose to receive home-based medical care. Allowing his condition to increasingly worsen, he died 7 months postoperatively. We encountered a case of malignant peritoneal mesothelioma discovered during a surgery for a right incarcerated inguinal hernia.
