RESUMO
The presence of schistocytes can be responsible for spurious thrombocytosis and spuriously low red blood count (RBC). The hemoglobin concentration will be correct (as the method usually used, destroys the red cells and converts a substantial proportion of the hemoglobin to a stable pigment) but mean corpuscular hemoglobin (MCH) is falsely high. The platelets and RBC histograms of the full blood count analyzers play an important role in the identification of schistocytes and must be carefully analyzed before reporting the previously full blood count parameters. In patients in ECMO, where can be expected the presence of a small number of schistocytes, this evaluation is particularly important to avoid wrong clinical decisions.
RESUMO
Crystalline inclusions in lymphocytes are unusual in chronic lymphocytic leukemia. They represent crystallized immunoglobulin (most frequently IgM-lambda) and their recognition facilitates the diagnosis of a lymphoproliferative disorder.

Toxic Shock Syndrome (TSS) is a severe acute disease characterized by high fever, hypotension, rash, multiple organ dysfunction and desquamation during convalescence. TSS is caused by toxin-producing strains of Staphylococcus aureus or Streptococcus pyogenes. TSS remains a rare but severe disease. Early diagnosis is important because specific treatments with antitoxin effects must be started as soon as possible. This manuscript presents a set of images that illustrate the main findings in the peripheral blood film of a patient with TSS.

Malaria represents a medical emergency. Without rapid diagnosis and treatment, it can progress and lead to severe complications and, eventually, death. Severe malaria is almost always caused by Plasmodium falciparum. Here, we present an image showing a set of hematological findings associated with severe malaria, highlighting the importance of a correct morphological diagnosis.

Granulocyte colony-stimulating factors may be responsible for a set of laboratory findings in the peripheral blood film that may be confused with those associated with important diseases like myeloproliferative neoplasms, infection, or megaloblastic anaemia. We present a case report of a 29-year-old woman where these laboratory findings are described.

MYH9 disorders are associated with sensorineural hearing loss, glomerular nephropathy, and presenile cataract. With this case report, we show the important role of the blood smear in its identification.
