title: 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.
