Anaplastic lymphoma kinase (ALK)-positive
diffuse large B-cell lymphoma (DLBCL) is a rare and distinct variant of DLBCL. It is classified as a unique subtype of DLBCL in the 2008
WHO classification of
lymphomas. No standard and effective
therapeutic regi-
men is available for ALK+DLBCL because it shows a more aggressive
clinical course and frequent
relapse. Therefore, a standardized and individualized
treatment is needed to benefit more
patients diagnosed with ALK+DLBCL through a multiple disciplinary team. This arti-cle presents a case of an ALK+DLBCL
patient who relapsed after
transplantation and was successfully treated with the
ALK kinase inhibi-tor
Crizotinib.
