Diffuse lymphoid follicles of the colon associated with colonic carcinoma.
In four patients aged 59-75 years, colonic carcinoma was associated with diffuse lymphoid follicles in the colon. In one case, the prominence and distribution of the lymphoid follicles corresponded to the progression and regression of the tumor bulk. It is extremely unusual to demonstrate lymphoid follicles, particularly diffuse, on barium enema in patients in this age range. The colonic carcinomas and lymphoid follicles are directly related, possibly representing an immune response.
