title: Three new cases of non-Hodgkin lymphoma with t(9;14)(p13;q32).
abstract: The majority of non-Hodgkin lymphomas of B-cell type (B-NHL) exhibit chromosomal abnormalities including many types of reciprocal translocations closely related to specific histopathologic entities. The t(9;14)(p13;q32) has been recognized as a primary genetic event directly involved in the development of lymphoplasmacytic lymphoma. In the 14 published cases, the t(9;14)(p13;32) seems to delineate a variety of low-grade B-cell disorders characterized by a common clinical history and immunopathologic similarities. We report here three new cases presenting a t(9;14)(p13;q32) with other chromosomal abnormalities which have been referred to as B-cell low-grade or high-grade malignant lymphoproliferative disorders. Two of these cases showed diffuse large B cell lymphoma morphology and two patients had a favorable clinical outcome. These data suggest that t(9;14)(p13;q32) is not restricted to low-grade lymphoma.
