Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) complicated with intestinal obstruction and perforation.

We report the case of a patient who comes to the emergency department with abdominal pain, oral intolerance and bloody stools, being diagnosed with intestinal obstruction secondary to a jejunal tumor with contained perforation. A laparotomy was performed with resection of the jejunal tumor and taking biopsies from lesions with similar characteristics in the rest of the small bowel compatible with monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL). The monomorphic epitheliotropic intestinal T-cell lymphoma is a rare intestinal tumor with a poor prognosis that is characterized by the proliferation of intraepithelial lymphocytes. The abdominal symptoms are nonspecific and the known major complications are intestinal perforation and obstruction. There is no standard therapeutic approach, being a combination of surgical resection, chemotherapy and autologous stem cell transplant.
