Myelodysplastic syndrome (MDS) is a poorly understood dreadful hematopoietic disorder that involves maturational defect and abnormalities in blood cell production leading to dysplastic changes and peripheral blood pancytopenia. The present work aims in establishing the mechanistic relationship of the expressional alterations of major tumor suppressor cascade, vital cell cycle inhibitors and hematopoietic microenvironmental components with the disease pathophysiologies. The study involves the development of N-N' Ethylnitrosourea (ENU) induced mouse model of MDS, characterization of the disease with blood film and bone marrow smear studies, scanning electron microscopic observation, mitochondrial membrane potential determination, flowcytometric analysis of osteoblastic and vascular niche components along with the expressional study of cleaved caspase-3, PCNA, Chk-2, p53, Ndn, Gfi-1, Tie-2, Sdf-1, Gsk-3β, p18 and Myt-1 in the bone marrow compartment...

The spleen selectively removes cells with intracellular inclusions, for example, detached nuclear fragments in circulating erythrocytes, called Howell-Jolly Bodies (HJBs). With absent or deficient splenic function HJBs appear in the peripheral blood and can be used as a simple and non-invasive risk-indicator for fulminant potentially life-threatening infection after spleenectomy. However, it is still under debate whether counting of the rare HJBs is a reliable measure of splenic function. Investigating HJBs in premature erythrocytes from patients during radioiodine therapy gives about 10 thousand times higher HJB counts than in blood smears...

An 8-year-old, male Rhesus macaque (Macaca mulatta), previously used for dengue virus (DENV) vaccine research with viral challenge, was presented with adult-onset, chronic, cyclic thrombocytopenia. Platelet number, morphology, and function were evaluated by automated hematology, peripheral blood smears, electron microscopy, flow cytometry, and impedance aggregometry. Bone marrow was evaluated by cytology. Both serum anti-dengue nonstructural protein 1 (NS1) antibodies and anti-platelet antibodies were detected by ELISA...

Thrombotic microangiopathy (TMA) occurring after acute pancreatitis is rarely described. Without prompt intervention, TMA can be, and often is, lethal, so prompt recognition is important. Here, we present a case of a 61-year-old woman with a history of alcohol misuse who presented with epigastric pain, nausea and vomiting after binge drinking. Elevated serum lipase and imaging were suggestive of acute-on-chronic pancreatitis. Although the patient's symptoms of acute pancreatitis subsided, her anaemia, thrombocytopenia and acute kidney injury worsened...

Pseudothrombocytopenia is a rare phenomenon in laboratory explained by in vitro agglutination of platelets. Microscopic examination of the peripheral blood smear is of key importance to confirm the diagnosis and to avoid any inappropriate or dangerous clinical and therapeutic decision. Its occurrence in a patient, under treatment with heparin, raises the problem of differential diagnosis of heparin-induced thrombocytopenia. The aim of this study was to eliminate any confusion between this purely artefactual phenomenon and heparin-induced thrombocytopenia...

INTRODUCTION: Aside from the extensive published data on immunophenotypic lymphocyte subsets in natalizumab-treated patients with multiple sclerosis (MS), an impact of natalizumab on lymphocyte morphology has rarely been studied. As patients treated with immunomodulating or immunosuppressive drugs are at risk for infectious disorders such as viral infections, knowledge of drug-derived changes in lymphocyte morphology may be beneficial in the diagnostic work-up in such clinical situations...

An 82-year-old man presented with high-grade fever, left flank pain with dysuria. Urine culture revealed the growth of Escherichia coli. Contrast-enhanced computed tomography features were suggestive of xanthogranulomatous pyelonephritis (XPN) of the left kidney. Serial hemogram studies revealed markedly raised white cell count with the presence of blast cells. On further evaluation by peripheral blood smears and bone marrow biopsy studies, a background disease setting of acute prolymphocytic leukemia was diagnosed...

BACKGROUND: Many hereditary thrombocytopenias and/or platelet function disorders have been identified, but diagnosis of these conditions remains challenging. Diagnostic laboratory techniques are available only in a few specialized centers and, using fresh blood, often require the patient to travel long distances. For the same reasons, patients living in developing countries usually have limited access to diagnosis. Further, the required amount of blood is often prohibitive for pediatric patients...

F E Craig
Laboratory professionals are in an ideal situation to identify CBC and peripheral blood smear findings that raise the possibility of a hematolymphoid neoplasm, and based on this information make recommendations for additional studies, such as flow cytometric immunophenotyping. In some circumstances a definitive diagnosis can be established from the combined peripheral blood morphologic and immunophenotypic findings obviating the need for bone marrow evaluation, such as for chronic lymphocytic leukemia. Occasionally flow cytometric studies are superior to morphologic assessment, such as in screening for hairy cell leukemia or identifying lymphocytic-variant hypereosinophilia...

REVIEW
D S Chabot-Richards, K Foucar
Numerous non-neoplastic and neoplastic conditions manifest with distinctive features in blood. Although automated complete blood count (CBC) data are essential, CBC information alone is insufficient for diagnosis. Consequently, morphologic review of blood smears is still relevant in the era of sophisticated automated analyzer systems. Pathologist interpretation of the peripheral blood smear, in conjunction with CBC and clinical information, can provide rapid diagnostic information and guide cost-effective targeted laboratory testing...

Chorea-acanthocytosis (ChAc) is a rare autosomal recessive inherited syndrome characterized by hyperkinetic movements, seizures, cognitive impairment, neuropsychiatric symptoms, elevated serum biochemical indicators and acanthocytes detection in peripheral blood smear. Vacuolar protein sorting 13A (VPS13A) gene mutations have been proven to be genetically responsible for the pathogenesis of ChAc. Herein, based on the typical clinical symptoms and neuroimaging features, we present two suspected ChAc cases which are further genetically confirmed by four novel VPS13A gene mutations...

We report an unusual case of systemic anaplastic large cell lymphoma (ALCL), ALK positive with leukemic involvement in a 57-year-old woman. The patient presented with a fulminant respiratory infection unresponsive to treatment requiring intensive care and ventilatory support. The CT scan demonstrated mediastinal and bilateral lymphadenopathy. On peripheral smear a few atypical lymphocytes were visualized. Based on the increasing number of atypical lymphocytes in the daily peripheral bloodsmears, the diagnosis ALCL was suggested...

Prolymhocytic leukemia (PLL) is a rare subtype of lymphocytic leukemias and its cells are immature lymphocytes. It is divided into 2 subgroups: T-PLL and B-PLL according to the lymphocytic origin of the cells. Discriminating B-PLL from other diseases with clinically-similar features is important because of the different treatment approaches and follow-up programs. Hereby, we report a 80-year-old woman presenting with fatigue, leucocytosis and mild anemia. Her peripheral blood smear evaluation revealed 85% prolymphocytes with moderately condensed nuclear chromatin, prominent nucleoli, and a faintly basophilic cytoplasm...

INTRODUCTION: While the presence of disseminated intravascular coagulation (DIC) has been implicated in worse clinical outcome in acute leukemia, the relationship between different subtypes of acute leukemia and the clinicopathologic features of DIC has not been systematically well studied. METHODS: In this study, we retrospectively reviewed 149 cases of newly diagnosed acute leukemia and assessed the utility of evaluating red blood cell morphologic features, and coagulation parameters in determining the presence of DIC as well as differentiating subtypes of acute leukemia...

In treatment of acute myeloid leukemia (AML), prognostic factors, including gene mutation and abnormal gene expression, enable risk stratification of patients. However, in the case of a small proportion of leukemic blast cells, such as AML associated with Down syndrome (AML-DS), it is not possible to examine prognostic factors precisely due to the large proportion of normal cells. Here, we present a novel method for examining prognostic factors by making a smear on a membrane slide glass from a small amount of diagnostic specimen and collecting highly pure leukemic blast cells by laser microdissection (LMD)...
