ABSTRACT

Two rare observations in which villous tumors affected the mucous membranes of the rectum and transverse colon are described. In one case the lesions extended for 60 cm, in the other the neoplasm occupied the entire inner surface of the rectum and colon as well as the adjacent area of the ileum, whereas in the area of the liver and spleen bends there were areas of adenocarcinoma. Both observations were characterized by marked inflammatory infiltration in some parts of the villous tumor.
