The most common form of DHL has translocations involving MYC and BCL2, also known as MYC/BCL2 DHL.     ///    "More recently, studies have suggested expanding the spectrum of MYC/BCL2 DHL to include cases that have concurrent MYC and BCL2 cytogenetic abnormalities, but not necessarily translocations. "    ///    "In this review, we discuss the clinicopathologic, immunophenotypic, cytogenetic, and prognostic features of MYC/BCL2 DHL. "    ///    "These tumors show overlap with MYC/BCL2 DHL, but are not equivalent. "    ///    "Most cases of MYC/BCL2 DHL morphologically resemble diffuse large B-cell lymphoma (DLBCL) or B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma. "    ///    MYC/BCL2 double-hit high-grade B-cell lymphoma..     ///    "In recent years, a number of case series of MYC/BCL2 DHL have been published. "
