The condition characterized by lymphoid tissues in the tonsils is lymphoepithelioma. This term refers to a type of cancer that is particularly associated with lymphoid tissue, which is found in the tonsils and other areas of the lymphatic system. Lymphoepithelioma is often linked to certain viral infections, such as Epstein-Barr virus, and is known for its association with nasopharyngeal carcinoma. The presence of lymphoid structures in the tonsils is a significant defining feature, distinguishing it from other cancers that may not be directly linked to lymphoid tissues.

Basal cell carcinoma, medullary carcinoma, and squamous cell carcinoma do not involve the specific relationship with lymphoid tissues within the tonsils as prominently as lymphoepithelioma does. Each of these other carcinomas has its own distinct characteristics and histological features, primarily relating to the type of cells involved and their location, rather than the lymphoid tissue association found in lymphoepithelioma.
