Abstract

As the number of long‑term cancer survivors is increasing, the incidence of post‑irradiation malignant mesothelioma may also increase. We herein present the case of an 85‑year‑old female patient with a history of several surgeries for solid tumors and radiotherapy to the pelvis, who presented with abdominal pain and diarrhea. The patient's general condition gradually worsened and she succumbed to cardiopulmonary arrest triggered by vomiting ~3 months after the onset of the abdominal symptoms. An autopsy revealed malignant intestinal obstruction caused by peritoneal mesothelioma. Irradiation is a known risk factor for malignant mesothelioma, which may develop ~10‑30 years after radiotherapy. To the best of our knowledge, this is the first report of a patient with malignant mesothelioma developing ~50 years after radiotherapy. The aim of the present study was to remind physicians that malignant mesothelioma should be considered in the differential diagnosis of patients with a history of radiotherapy who present with gastrointestinal symptoms.
