Abstract:
The present case involved a man aged about 70 years. He visited our hospital with the main complaint of abdominal pain. We diagnosed him with intestinal obstruction, and we decided to perform surgery. White knot sections were spread inside the abdominal cavity, and the small intestine appeared as a single block. This block was resected and examined for peritoneal mesothelioma. Peritoneal mesothelioma is thought to have incubation period of 20-25 years after exposure to asbestos, and the number of affected patients will increase in the future. In some cases, peritoneal mesothelioma occurs only in the peritoneum; therefore, diagnosis often becomes difficult. Once intestinal obstruction occurs, administering chemotherapy is difficult. Therefore, early diagnosis is thought to be very important.
Insights
A 70-year-old man with abdominal pain was diagnosed with intestinal obstruction caused by peritoneal mesothelioma. Early diagnosis is crucial for effective treatment of this asbestos-related cancer, as chemotherapy is difficult once obstruction occurs.
Area of Science:
- Oncology
- Gastroenterology
- Pathology
Background:
- Peritoneal mesothelioma is a rare cancer linked to asbestos exposure, with a long incubation period.
- Diagnosis can be challenging, especially when symptoms are non-specific or limited to the peritoneum.
Observation:
- A 70-year-old male presented with abdominal pain, leading to a diagnosis of intestinal obstruction.
- Surgical exploration revealed white knot-like sections throughout the abdominal cavity, with the small intestine encased in a singular block.
Findings:
- Resected tissue confirmed the presence of peritoneal mesothelioma.
- The case highlights the potential for peritoneal mesothelioma to manifest initially as intestinal obstruction.
Implications:
- Early detection of peritoneal mesothelioma is critical for timely intervention and improved patient outcomes.
- The increasing incidence of asbestos-related diseases necessitates heightened awareness and diagnostic vigilance.
