In children with newly diagnosed acute myeloid leukaemia (AML), myeloid sarcomas (MS) of the central nervous system (CNS) are rare. Since MS involving the CNS are potentially curable, timely recognition is paramount. Establishing a diagnosis may be problematic as they can easily mimic primary CNS neoplasms. We report the case of a 5-year-old boy with AML with t(8;21)(q22;q22) rearrangement who presented with a massive intracranial MS and rapid clinical deterioration suggestive of a meningioma or a primitive neuroectodermal tumour...

An 18 year old male, known case of Type 1 Diabetes Mellitus was admitted in view of diabetic ketoacidosis. With normalization of blood sugars patient developed gross reddish discoloration of urine. Urine routine microscopy did not reveal RBCs or RBC casts. Peripheral blood smear revealed bite cells, Heinz bodies and spherocytes. Thus a diagnosis of hemolytic anemia with hemoglobinuria was made. Patient's glucose-6-phosphate dehydrogenase (G6PD) levels were below the normal range. G6PD, an enzyme of the HMP shunt, is the most common enzyme defect causing hemolytic anemia...

Acute lymphoblastic leukemia is characterized by unchecked proliferation of malignant lymphoblasts which replaces the normal bone marrow culminating in anemia due to red blood cells inadequacy as well as in easy bruising/bleeding secondary to insufficient platelets production. Even the white blood cells which are produced excessively are immature and abnormal. ALL is the most common hematological malignancy in children. Most commonly, patients present with lymphadenopathy, recurrent infections, bleeding, fatigue, and bone pains...

INTRODUCTION: Various studies confirm the biocompatibility and efficacy of clips for certain target tissues, but without any comparative analysis of hematological parameters. Therefore, we conducted a study to assess the possible association of the implantation of titanium and plastic clips in the neurocranium with possible morphological changes in the blood cells of experimental animals. MATERIALS AND METHODS: As a control, the peripheral blood smears were taken before surgery from 12 adult dogs that were divided into two experimental groups...

BACKGROUND: Transfusion-transmitted babesiosis (TTB) has been rapidly increasing in incidence since the beginning of the 21st century. Asymptomatic individuals with Babesia infection are able to donate blood in the United States because of the lack of specific blood donation testing. Blood products collected in Babesia-endemic areas are distributed nationally; thus, clinicians in nonendemic states may fail to include babesiosis in the differential diagnosis of a patient who had a recent transfusion history and a fever of unknown origin...

In recent years, several automated analysers that prepare and stain blood smears have been introduced in clinical laboratories. Despite the use of instrumental settings based on physical characteristic of individual samples, traumatic injuries of neutrophil and lymphocytes can be observed. Some samples present a very high percentage of damaged cells, allowing the speculation that a cellular susceptibility may enhance mechanical traumatism. These artefacts can puzzle morphological evaluation in both traditional and digitised microscopy; in addition, unskilled operators can be misled...

Malaria is one of the leading causes of infectious disease in returning travelers from the tropics. Diagnosis of malaria is typically performed by examination of Giemsa-stained thick and thin peripheral blood smears, which is time-consuming, labor-intensive and requires high levels of proficiency. Alternatively, loop-mediated isothermal amplification (LAMP) is a new molecular method, which is rapid, sensitive, and requires less capital equipment and technological training. We conducted a retrospective study comparing two formats of a commercial LAMP assay (Meridian illumigene® Malaria [M] and Malaria Plus [MP]) versus reference microscopy on archived blood specimens (n=140) obtained from unique returning travelers suspected of having malaria...

Gray hair syndromes are rare syndromes which have an autosomal recessive inheritance and are characterized by pigmentary dilution of skin and hair, defects in immunological function, and nervous system defects. They comprise three disorders namely Chediak-Higashi syndrome (CHS), Griscelli syndrome (GPS), and Elejalde syndrome. Clinically, it is difficult to distinguish these disorders as their clinical features may overlap. Hence, to make a correct diagnosis and differentiate between CHS and GPS light microscopic examination of skin and hair shafts as well as peripheral blood smear evaluations should be done...

We evaluated an extended time in the microscopic review in samples in which the potential clinical information could be increased with respect to those that could be achieved with the usual laboratory methodologies. We used samples containing nucleated red blood cells in a small amount and cytopenic samples. For these purposes for each peripheral blood smear, the timing of eye-count differential was increased up to 20 min, regardless of the final number of cells which could be counted. In addition, an automated system for digital analysis of peripheral blood smears was employed and the number of cells counted was brought up to 1000 leukocytes...

Differential treatment strategies are applied in thrombotic microangiopathy (TMA) according to the sub-classifications. Hence, it is worthwhile to overview clinical manifestations and outcomes of overall TMA patients according to sub-classifications. We analyzed TMA patients whose serum lactate dehydrogenase levels >250 IU/L, with the presence of schistocytes in their peripheral blood smear, or with typical vascular pathologic abnormalities in their renal biopsy. We compared clinical manifestations including overall survival (OS) and renal survival according to TMA causes...

Gastric adenocarcinoma is a common neoplasia and is responsible for up to 30% of the overall deaths due to cancer. Advanced disease is mostly characterized by peritoneum, liver, and lung involvement. The spread of the disease to the bone is rare, and bone marrow dissemination is even rarer. In this setting, leukoerythroblastosis may be the initial manifestation of the disease. The authors report the case of a 64-year-old Caucasian man who sought medical care complaining of back pain, weakness, and weight loss...

Normoblasts may be seen in peripheral blood smear of newborns. The number of normoblasts per 100 white blood cells is generally in the range of 0-10.They can be seen more common than usual in hypoxic condition, because intrauterine hypoxia increases the production of red blood cells. However, multinucleated normoblasts in a newborn caused by hypoxia haven't been reported before. We present a newborn with multinucleated normoblasts secondary to intrauterine hypoxia. This case is important; because it is the first time multinucleated normoblasts in peripheral blood smear of a hypoxic newborn has been detected...

Historically, the diagnosis and classification of acute leukemia involved morphologic review of blasts in the peripheral blood and bone marrow smears and cytochemical staining. Cytochemical stains, which are enzymatic colorimetric reactions that occur in the cells of interest, were necessary to assign and confirm myeloid and lymphoid lineage. In the current WHO 2008 Classification of leukemia, immunophenotyping and cytogenetic analysis have largely replaced cytochemical staining in the characterization of acute leukemias...

BACKGROUND: Red blood cells (RBC) resembling the silhouette of a fish are rarely observed in peripheral blood (PB) smears. In this study, we determined the frequency of occurrence of fish-shaped RBC in different haematologic diseases. METHODS: We examined PB smears of patients with iron deficiency anaemia (IDA) (n=23), β-thalassaemia minor (BTM) (n=30), sickle cell disease (SCD) (n=7), autoimmune haemolytic anaemia (AIHA) (n=13), microangiopathic haemolytic anaemia (MAHA) (n=11), hereditary sphaerocytosis (HS) (n=4), hereditary elliptocytosis (HE) (n=3), vitamin B12 and folate deficiency (n=15), anaemia in liver disease (LD) (n=17), myelodysplastic syndrome (MDS) (n=15), acute myeloid leukaemia (AML) (n=29), chronic myeloid leukaemia (CML) (n=18), primary myelofibrosis (PMF) (n=12), chronic myelo-monocytic leukaemia (CMML) (n=15) and 21 healthy controls by light microscopy for the occurrence of fish-shaped erythrocytes...

BACKGROUND: Plasmodium knowlesi is primarily responsible for zoonotic malaria in several Southeast Asian countries. Precise identification of the parasite in the blood of patients presently relies on an expensive and elaborate PCR procedure because microscopic examination of blood and other available field identification techniques lack adequate specificity. Therefore, the use of a simple and inexpensive dual-colour fluorescence in situ hybridization (FISH) assay, analogous to FISH assays recently described for Plasmodium falciparum and Plasmodium vivax, was investigated as a potential tool for identifying P...
