Gray zone lymphoma: chromosomal aberrations with immunophenotypic and clinical correlations.

ABSTRACT: The term gray zone lymphoma has been applied to tumors that demonstrate transitional morphologic and immunophenotypic features between classical Hodgkin's lymphoma and diffuse large B-cell lymphoma, especially primary mediastinal large B-cell lymphoma. Histopathological and genetic data are limited for these unusual cases. We analyzed cases of gray zone lymphoma (n=27), mediastinal composite lymphoma (n=3) and mediastinal synchronous/metachronous lymphoma (n=3) by morphology, immunophenotyping and fluorescence in situ hybridization. Mediastinal involvement was assured in 24/33 patients (73%). The patient cohort showed a male predominance (M:F ratio; 20:13) and a median age of 32 years (range, 16-91 years). Patients with mediastinal disease were significantly younger (median age: 29.5 years
