Unsuspected non-Hodgkin's lymphoma of the tonsils and adenoids in children

Six children with lymphoreticular malignancy arising in the pharyngeal tonsils or adenoids are presented. Early clues to the possible malignant nature of the enlargement of tonsils and adenoids in this series include: asymmetric and persistent enlargement, the absence of such manifestations of infection as fever or pain, and the association of atypical adenopathy. Lack of clinical suspicion brings with it the risk of delayed diagnosis and possible compromise of optimal therapy.
