Abstract:
Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a very rare intestinal T-cell lymphoma which is observed most frequently in the jejunum. MEITL is prone to cause intestinal perforation and the prognosis is very poor when it occurs. Here we report a fatal case of MEITL causing jejunal perforation at the time of diagnosis in a 79-year-old man. The patient underwent emergency surgery for jejunal perforation caused by MEITL but died 3 months after the initial visit due to prolonged peritonitis. It is desirable to establish a method to predict cases with intestinal perforation, and systematize the treatment strategies to avoid perforation.
Insights
Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a rare intestinal cancer. This case report details a fatal MEITL diagnosis complicated by jejunal perforation, highlighting the need for predictive methods and improved treatment strategies.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is an exceptionally rare and aggressive form of T-cell lymphoma.
- MEITL predominantly affects the jejunum and is associated with a high risk of intestinal perforation.
Observation:
- This report details a fatal case of MEITL in a 79-year-old male patient.
- The patient presented with jejunal perforation directly attributable to MEITL at the time of diagnosis.
Findings:
- The patient underwent emergency surgery for the perforation but succumbed to prolonged peritonitis three months post-visit.
- This case underscores the critical and often fatal complications associated with MEITL, particularly intestinal perforation.
Implications:
- There is an urgent need to develop predictive tools to identify patients at risk of intestinal perforation from MEITL.
- Systematizing treatment strategies is crucial to prevent perforation and improve outcomes for MEITL patients.
