A light and transmission electron microscopic study on the structure of splenic periarterial lymphatic sheath (PALS) was done in chicken of various age groups ranging from day-old to forty weeks. The PALS was noticed in all the age groups except day-old. PALS were observed as a diffuse lymphatic sheath adjacent to the central artery in all the age groups studied. It consisted of closely packed small lymphocytes and several medium to large sized lymphocytes and reticular cells. The lymphocytes of all sizes appeared to have high nuclear cytoplasmic ratio. Few macrophages and plasma cells were also found towards the periphery of the PALS. The macrophages contained vacuoles, phagocytosed materials and granules in the cytoplasm. The plasma cells showed a very large Golgi region and well developed rough endoplasmic reticulum within the cytoplasm.
