We experienced 3 patients with advanced intestinal tuberculosis. 1) All cases were 20 year-old female, 2 of whom had minimal pulmonary tuberculosis, the remaining 1 case had a past history of miliary pulmonary tuberculosis. 2) One case was complicated with Pityriasis circinata Toyama on the back of both hands which disappeared with the improvement of the intestinal tuberculosis. 3) One case with severe intestinal bleeding was suspected to have intestinal tuberculosis and nonspecific ulcerative colitis according to clinical and pathological data. 4) All cases improved with anti-T.R. therapy (chemotherapy). 5) In cases of patients with symptoms of chronic diarrhea and chronic colitis of unknown origin we must always consider a possibility of intestinal tuberculosis as one of the causes
