Philadelphia-positive lymphoblastic lymphoma: a case report and review of the literature.

Philadelphia positive acute lymphoblastic leukemia is well documented nowadays but very little is known about Philadelphia positive lymphoblastic lymphoma (LBL). Only two cases are available in literature and both of them died during treatment whereas the patient treated in our center is still alive 3 years after the initial diagnosis. A chemo-free regimen was used in induction with dasatinib plus steroids with local radiotherapy on the mass, and then the patient underwent bone marrow transplant. Philadelphia positive lymphoblastic lymphoma is a difficult diagnosis to make and the management of this extremely rare disease is very challenging.
