The mature T- and NK-cell lymphomas are rare, comprising approximately 10 % of all malignant lymphomas. The incidence of T-cell lymphoma is variable around the world, with a higher incidence compared to B-cell lymphomas in the Asian basin. While the overall incidence of B-cell lymphomas has begun to decline in the United States, the incidence of T-cell lymphomas continues to rise. The evolution of T-cell lymphoma biology and therapy has lagged behind that of B-cell lymphomas, partly due to the fact that in the lymphoproliferative world, T-cell lymphomas have only recently been identi fi ed as distinct from their B-cell counterparts.
