title: Tn polyagglutinability occurring in a patient with B cell lymphoma.
abstract: A case of polymorphic immunocytoma (B cell lymphoma) coinciding with expression of Tn antigen on a population of erythrocytes is presented. Tn activation was found incidentally by screening blood samples of patients suffering from hematologic malignancies with a Tn specific lectin from Salvia sclarea. So far, Tn activation has been reported only in apparently healthy subjects or in subjects suffering from or developing myeloid leukemia.
