The objective of our study is to comment on three cases of non-Hodgkin's lymphoma (NHL) of the palatine tonsil treated at Rio de Janeiro Federal University's Hospital. The NHL occur in extranodal sites in 20-30% of the cases, of these, 10-30% are seen in the head and neck. Sixty to seventy percent of the NHL of the head and neck are present in the Waldeyer's ring, and we see aproximately 80% of the Waldeyer's ring NHL in the tonsil. We conclude that NHL of the tonsil is a rather uncommon condition that should be promptly diagnosed for a correct treatment and follow-up.
