[Acute cytomegalovirus colitis after bone marrow transplantation].

Cytomegalovirus infection of the digestive tract is rare and particularly severe after transplantation. Colon is the most often affected part of the digestive tube. We present the case of acute cytomegalovirus colitis that occurred five months after a bone marrow transplantation. An emergency subtotal colectomy with sigmoidostomy and ileostomy was performed followed six weeks later by an ileorectal anastomosis. The pathologic specimen showed cytomegalovirus inclusion bodies proving the diagnosis.
