Abstract:
The submucosa of small intestine, showed Peyer’s patches of different sizes and shapes. The lymphoid follicles in the submucosa of duodenum were arranged in single row but in jejunum and ileum, lymphoid follicles were arranged in two irregular rows and separated by distinct inter follicular regions. Each lymphoid follicle showed outer darkly stained area called cortex and inner lightly stained region called medulla, distinct inter follicular area, dome region and follicle associated epithelium. Some of the jejunum and ileal lymphoid follicles showed raised areas called domes which were composed of a broad basal portion and a narrow apical part. These domes were lined by a distinct layer of epithelium called follicle associated epithelium which consisted of columnar enterocytes and few “M” cells but devoid of goblet cells. In large intestine, the number of lymphoid follicles were less and most of the submucosa was occupied by the adipose tissue. The lymph glandular complexes were noted in the lamina propria and submucosa of the colon and in the lamina propria of rectum.
