Photomicrograph of a lymphatic nodule. This photomicrograph shows a section of the wall of the small intestine (duodenum). Short villi and intestinal glands are present in the upper part of the micrograph. A lymphatic nodule (LN) occupies most of the remainder of the micrograph. The lighter central region of the nodule is the germinal center. The lymphocytes in the germinal center are larger than those in the more dense region of the nodule. They have more cytoplasm; consequently, their nuclei are more dispersed, giving the appearance of a less compact cellular mass. x120.
