Adult T-cell leukemia with leukemia cell infiltration into the gastrointestinal tract

This is the authors' abstract. We don't add key points for this paper.

Five cases of untreated adult T-cell leukemia (ATL) with leukemia cell infiltration into the gastrointestinal (GI) tract were reported. X-ray findings of the GI tract showed diffuse abnormal mucosal patterns throughout the GI tract in all five patients. Endoscopic findings corresponded well with the x-ray findings. Pathologic examination of biopsied specimens from all five patients revealed diffuse and extensive leukemic infiltration into the stomach and/or the large intestine.
