Abstract:

A study was conducted on the lingual tonsil of six male crossbred goats of six months of age. The lingual tonsil could not be identified macroscopically but in histological sections aggregations of lymphocytes were seen within the core of vallate papillae present in the root of tongue. The stratified squamous keratinized surface epithelium was composed of strata basale, spinosum and corneum, arranged in twelve to fifteen layers and measured 720.35±13.20µm. At the region of small crypts, the surface epithelium presented fewer cell layers and was called reticular epithelium or lymphoepithelium. It measured 263.48±5.25µm in height and was associated with lymphoid tissue. Hassall’s corpuscles were occasionally detected towards the outer surface epithelium. Propria-submucosa in the core of vallate papillae presented lymphoid tissue which was devoid of any lymphoid nodules. 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. Scanning electron microscopy of the vallate papillae revealed an elevated structure surrounded by deep narrow crypt and was covered by squamous epithelium with dense microplicae and distinct cell junctions. Large numbers of lymphocytes were seen within the propria-submucosa of the vallate papillae.
