AbstractMonomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a primary intestinal T-cell lymphoma and other organ involvement is very rare. A rare case of MEITL involving the lung and brain is herein reported. The patient developed panperitonitis with a small intestinal perforation, and emergency surgery was performed. The pathological findings from the surgical specimens demonstrated atypical lymphoid cells which were positive for CD3, CD8, and CD56. Moreover, the pathological findings of lung specimens taken by bronchoscopy were consistent with those of the small intestine. It is therefore important to include the possibility of MEITL in the differential diagnosis of cancer patients.
