Pathological counts Case B14 Pseudopelger cells Diagnosis: B-PLL An 86-year-old woman treated for breast cancer in 2008 with surgery and postoperative irradiation. Six years later she now consulted her general practitioner because of increasing fatigue and unspecific abdominal and back pain. Blood tests revealed leukocytosis ( count 44,9x10 9 /l), with 30% blast-like cells containing nucleoli, but also some pseudo Pelger-Huët and immature forms in the granulopoiesis, together with a very high LDH >79 µkat/l (ref <4 µkat/l). Clinical examination revealed palpable splenomegaly and an enlarged untender left axillary lymph node. CT-scan showed some moderately enlarged lymph nodes and confirmed slight splenomegaly. A bone marrow investigation showed massive infiltration of blast-like cells. Flow cytometry of bone marrow showed a monoclonal cell population expressing CD19 and the light chain lambda. These cells were positive for CD10, CD20, CD22, IgD, and IgM, but negative for nuclear TdT, CD5, CD23, CD200, and cyclin D1. FISH for the Philadelphia chromosome was negative. The diagnosis based on the bone marrow investigation was B-prolymphocytic leukemia (B-PLL). She received one course of cyclophosphamide and rithuximab treatment with transient cytopenia afterwards, but at this follow up the count had increased rapidly again. The histogram shows an abnormal shape that could indicate immature findings, DE-flag. : Anemia with increased RDW. : Increased numbers.

Pathological counts Case B15 Plasma cells Diagnosis: Plasma cell leukemia This woman was initially followed from 1997 without treatment for smouldering myeloma with M-protein IgA-kappa and Bence Jones proteinuria, while working in a prison ward. After disease progression she underwent her first autologous hematopoietic stem cell transplantation in 2001, and another one in 2007, on both occasions after conditioning with highdose melphalan, and followed by interferon maintenance. Progressing disease necessitated other treatments since 2011, including the immunomodulators thalidomide and lenalidomide, with neuropathy developing after the former. Now she developed plasma cell leukemia and problems with bleeding due to low platelet counts. Unfortunately her condition worsened despite bendamustine and prednisone treatment for the plasma cell leukemia, and she succumbed to the malignancy not much later. The histogram shows leukocytosis with an abnormal distribution in the Mid- and Gra-cells populations.
