label: Mediastinal Gray-Zone Lymphoma
label_lc: mediastinal gray-zone lymphoma
description: "A mediastinal lymphoma with molecular, morphologic, immunophenotypic, and clinical features of both mediastinal (thymic) large B-cell lymphoma and classic Hodgkin lymphoma.  The identification of this group of lymphomas, along with recent gene expression profiling results (PDL2 gene expression in both mediastinal (thymic) large B-cell lymphoma tissues and Hodgkin lymphoma cell lines), further supports the hypothesis that mediastinal (thymic) large B-cell lymphomas and classic Hodgkin lymphomas are related entities."
