The bone marrow examination is an essential investigation for the diagnosis and management of many disorders of the blood and bone marrow. The aspirate and trephine biopsy specimens are complementary and when both are obtained, they provide a comprehensive evaluation of the bone marrow. The final interpretation requires the integration of peripheral blood, bone marrow aspirate and trephine biop...

Differential cell counts were performed on 200 paired bone marrow aspirates and trephine biopsy specimens to compare the distribution of cell types. Relatively more immature myeloid cells were found in the trephine biopsy specimens and relatively more polymorphs and lymphocytes in the aspirates. Two methods for sampling areas of the trephine biopsy specimens for counting were assessed, and the ...

Sunitinib is an oral tyrosine kinase inhibitor which prevents tumor growth and metastatic progression. It was approved for treatment of advanced renal cell cancer, gastrointestinal stromal tumor and advanced pancreatic neuroendocrine tumors. It has several adverse reactions on multi organ systems including hematologic system. Although the neutropenia and thrombocytopenia commonly happens as Gra...

Sulphur mustard (SM) is an alkylating agent that was first used as a chemical warfare agent during the First World War in 1917. SM is readily absorbed from the skin, respiratory and gastrointestinal tract and is distributed to several organs. SM may act rapidly and persistently upon DNA replicating mechanism of the individual cells during mitosis particularly in the hematopoietic system. O...

Acute lymphocytic leukemia (ALL) is one of the frequent malignancies in pediatrics and involves bone marrow and extramedullary sites. Proptosis as extramedullary involvement of leukemia usually present in acute and chronic myeloid leukemia. It is extremely rare for ALL to present initially as proptosis.Here, a-21-month-old boy was presented with proptosis without any associated symptoms except ...

extramedullary hematopoiesis is characterized by the presence of hematopoietic tissue outside the bone marrow. extrathoracic extramedullary hematopoiesis is a rare and usually asymptomatic condition. we report a case of a 38-year-old female with paraspinal and presacral extramedullary hematopoiesis with polycythemia vera. clinical and laboratory evaluation, along with radiological and histopath...

Hairy cell leukemia (HCL) is a rare chronic lymphoproliferative disease. LSV characterized by inflammation of small vessels. Its association in the literature and HCL can be seen etiology, although relationship between 2 diseases far from clear. Here, we aimed to present case with constitutional symptoms, palpable purpuric lesions on body diagnosed as bone marrow biopsy.
