A man with acute myelogenous leukemia, treated with chemotherapy, had a decrease in circulating formed blood elements. Bone marrow biopsy revealed necrosis. Imaging with In-Ill chloride demonstrated activity in the liver, but not in the spleen or bone marrow. Eighteen days later, the circulating blood count had risen; a repeat bone marrow biopsy showed the return of blood cell precursors....

Introduction: Haematological and nonhaematological diseases affecting the bone marrow may be primarily or a secondarily spread to marrow. In most of cases, diagnosis can arrived at by detailed history, physical examination few simple investigations. Bone is very useful tool in hematological non-hematological diseases. Materials Methods: This retrospective study was done department haematology, ...

A study of seven patients with AILD has confirmed previously reported cytological and immunological changes in the peripheral blood. In themselves these changes should not be considered as specific. Histological examination of the bone marrow may show more characteristic lesions which involve haemopoietic, lymphoid, and stromal cells. Three patients had bone marrow features similar to myelofibr...

Cutaneous presentation revealing acute myeloid leukemia (AML) is rare, and the prognosis poor. We report a case of an 11-month-old male who presented with cutaneous lesions present as diffuse purplish papulo-nodular lesions, M5 leukemia. Skin biopsy immunohistochemical examination, combined routine blood analysis bone marrow contributed to early diagnosis. However, despite intensive chemotherap...

Background: Previous studies about the relationship between bone marrow megakaryocyte count and the chronicity of ITP has yielded paradoxical results. The aim of the present study was to investigate any relationship between the megakaryocyte count in the bone marrow and the chronicity of ITP. Materials and Methods: This study was performed to compare the primary bone marrow aspiration megakar...

Bone marrow metastasis from solid tumors is usually accepted as not only incurable, but as fatal. Colon cancer is a relatively rare malignancy that involves the bone marrow, and to the best of our knowledge, there have been no studies in the literature reporting only bone marrow metastasis of colon cancer as the first presentation of relapse. The present study reports the case of a 74-year-old ...

In this study, an unusual case of osteoma is presented, whereby a bone marrow osteoma was identified in the tibia. No previous cases of bone marrow osteoma have been reported. In this case, an eight-year-old male presented with discontinuous discomfort in the right distal calf for six months. Radiological examination and computed tomography revealed a radiopaque lesion within the affected bone....

Histological examination of the bone marrow based on an evaluation of trephine biopsies is the gold standard for the diagnosis of bone marrow involvement in non-Hodgkin’s lymphomas while immunohistochemistry and molecular analysis may increase the accuracy and the sensitivity of lymphoma detection. Subtyping lymphomas on the trephine, according to the REAL classification, needs further investig...

BACKGROUND Peripheral blood leucopenia and thrombocytopenia are the main manifestations in severe fever with thrombocytopenia syndrome (SFTS) patients. However, the underlying causes are poorly understood. Therefore, we aimed to investigate cytology of bone marrow samples collected from SFTS patients. METHODS 10 SFTS patients were identified by typical clinical manifestations, detection of pe...

  Background and Objectives: Bone marrow necrosis (BMN) is a rare and ominous complication of wide variety of diseases including hematologic malignancy. This study was performed to identify frequency and the underlying associated diseases of marrow necrosis. Materials and Methods: In this descriptive study, totally 850 bone marrow trephine biopsies related to living patients at the Pathology ...
