Abstract

A comparative morphological study of intestinal wall tissues in such chronic colonic diseases, such as Crohn's disease, ulcerative colitis, and catarrhal rectal fistulas, allows the formation of giant cells of foreign bodies and their granulomas and sarcoid-type ones to be nonspecific. Their spread through and outside the colon is due to the migration of foreign bodies along the lymphatic vessels. Foreign inclusions of different shapes and structures in the cytoplasm of giant cells suggest that the colon contains the multiple particles of varying antigenic nature, which induce a unified morphological response medicated by innate and adaptive immunity cells. Consequently, the universally accepted substantiation of the diagnosis of Crohn's disease by the presence of granulomas is unconvincing.
