Two cases of multiple lymphomatous polyposis (MLP) are presented, involving different segments of the gastrointestinal tract. Both cases display the characteristic clinical and pathologic features of MLP. In addition, we were able to document, for the first time, the endoscopic ultrasonographic findings in this disease. This new ancillary diagnostic technique was found to be very helpful in the evaluation of the structural changes of the wall of the gastrointestinal tract and in the detection of affected lymph nodes.

We report a 45-year-old woman with chronic ulcerative colitis complicated by primary biliary cirrhosis and concomitant chronic pancreatitis. The combination of primary biliary cirrhosis and ulcerative colitis has only rarely been reported, and the association of these diseases with chronic pancreatitis is even rarer. These systemic manifestations of ulcerative colitis should be looked for more often.

Autoimmune hemolytic anemia is a rare complication of ulcerative colitis. This report chronicles a patient successfully treated with steroids, and reviews treatment in previously reported cases. The fact that 21% of patients recovered with steroid therapy encourages a conservative approach before surgery is considered.

Spontaneous umbilical fistula developed in two young women with Crohn's disease. This peculiar complication of Crohn's disease has been rarely reported. In view of the complete closure of the fistulas with medical treatment, we recommended conservative medical management, at least initially, in such patients.
