A study was conducted on the lingual tonsil of six adult male crossbred goats and Large White Yorkshire pigs. The lingual tonsil could not be identified macroscopically but in histological sections aggregations of lymphocytes were seen within the core of mechanical conical papillae in pigs and vallate papillae in goats. The stratified squamous surface epithelium of lingual tonsil was keratinized in goats while non-keratinized in pigs. At the region of crypts, the surface epithelium consisted of few cell layers associated with numerous lymphocytes and was called as reticular epithelium or lymphoepithelium. Hassall’s corpuscles were occasionally detected towards the outer surface epithelium. Propria-submucosa in the core of conical papillae in pigs presented numerous lymphatic nodules of different shapes and dimensions and were separated from the surrounding adipose tissue and glands by a dense connective tissue capsule. However in goats the lymphoid accumulation in vallate papillae was devoid of any lymphatic nodules and was not encapsulated. Lymphoid cell aggregations were also noticed in between glandular acini, striated muscles and around the ducts of mucous glands which opened towards the surface epithelium of the vallate papillae.
