In the United States, lymphoblastic lymphoma is relatively rare, comprising only 2% of all non-Hodgkin lymphomas (NHLs). The T-cell phenotype accounts for more than 80% of cases, with the remainder of B-cell origin. T-lymphoblastic lymphoma (T-LBL) accounts for 25-30% of childhood NHL and is closely related to T-lymphoblastic leukemia (T-ALL). [6] Lymphoblastic lymphoma predominates in young adults and adolescents with a median age at diagnosis of 20 years (in adults: median age, 27 y for men; 50 y for women) and a slight m  ale predominance (male-to-female ratio, 2:1).
