RELAPSE OF PRIMITIVE MEDIASTINAL LYMPHOMA AS A MYELOID MASS FOLLOWING BEAM AUTOLOGOUS TRANSPLANT AND SUBSEQUENT REFRACTORINESS TO MATCHED UNRELATED UMBILICAL CORD BLOOD ALLOGRAFT

Abstract

Outlining the treatment for an unclassifiable lymphoid malignancy is often difficult. A highly undifferentiated lymphomatous mass that relapsed in spite of intense chemotherapy and autologous transplant is reported. At relapse, there was differentiation into myeloid lineage. Though remission was achieved with AML-type reinduction chemotherapy, the mass recurred post allogenic cord blood stem cell transplant.
