Chronic lymphocytic leukemia (CLL) typically pursues a prolonged course. Its transformation into a more aggressive lymphoma occurs in 2-8% of all patients. Most commonly, diffuse large B-cell lymphoma develops. Transformation into a classical Hodgkin's lymphoma (cHL) occurs in <1%. Plasmablastic transformation has been only rarely reported. Cases of synchronous divergent transformation of CLL into a composite lymphoma are exceedingly rare. We describe the unique occurrence of the transformation of a long-standing CLL into a synchronous clonally related cHL as well as plasmablastic lymphoma (PBL) in an 85-year-old female patient. After 10 years of asymptomatic CLL, our patient was treated with a rituximab-chlorambucil scheme in combination with pegfilgrastim for recurrent infections and the development of B symptoms. Five cycles (of six planned) were administrated with no adverse effects. After the fifth cycle, lymphadenopathy with pronounced B symptoms appeared. Histology showed the presence of cHL in the lymph node, while the bone marrow was infiltrated by PBL. Our patient died in sepsis not receiving further specific oncologic treatment due to her poor general condition. Additional cytogenetic and molecular studies showed that this was a case of mutated CLL with trisomies of chromosomes 12, 3, and 18 (a rare specific +12 plus other-non+19 CLL subgroup). The presence of trisomy 12 has also been proved in plasmablasts and in cHL cells.
