 A woman in her sixties with a 5 month history of CMMoL was admitted to Fujita Health University Hospital because of left flank pain in March, 2008. After admission, abdominal pain reduced but diarrhea and melena appeared, so colonoendoscopy was indicated. Numerous small round elevated lesions like multiple lymphomatous polyposis with erosion or fibrin plaque on their tops were found from the recum to the cecum. Leukemia cell infiltration to the mucosa was revealed histopathologicaly in all biopsy specimens. But when we made this diagnosis, the patient's condition was very severe, so she could not be receive curative therapy. Granulocytic sarcoma of the colon associated CMMoL is very rare and only 2 cases have been reported before. Including our case, macroscopic findings differed.
