Hodgkin's lymphoma variant of Richter's syndrome.

Chronic lymphocytic leukemia/small lymphocitic lymphoma (CLL/SLL) is low-grade malignant lymphoprolipheration, that has tendency to convert to a higher-grade neoplasm over time. More common is the development of a diffuse large cell lymphoma or transformation into prolymphocytic cell population. In rare cases, 0.1-0.5% of patients develop multiple myeloma or Hodgkin's disease. We present 65-year-old female with Hodgkin's variant of Richter's syndrome. On the basis of clinical simptoms, cytological, hystological and immunohistological finding in April 2008 CLL/SLL were diagnosed. The patient was treated with 8 courses of R-CHOP. After 10 months, FNA of the one of the enlarged lymph node on the neck was performed. The diagnosis was Hodgkin's disease. Immuno-hystological studies of the lymph node was consistent with type I Hodgkin's type of Richter's syndrome. Patient was treated with 3 courses of ABVD and radiotherapy.
