Angiocentric lymphomas (AL) involving the mid‐face are infrequent lesions. Their incidence seems to be higher in certain Asian and Latin American countries, where most of the reported series reveal a predominance of T‐cell lineage and a high frequency of EBV‐positive cells. The clinical and pathological features of 12 AL that affected the palate are presented. Immunophenotypic studies were performed in nine of these cases. Seven (77%) demonstrated T‐cell lineage, one was of B‐cell origin and one could not be classified. The high incidence of T‐cell lesions in this and other studies supports the existence of geographical and possibly of etiological differences in these neoplasms.
