Pancytopenia can be caused by a wide variety of etiologies that require evaluation of bone marrow. This is a cross sectional study carried out to identify the various findings in bone marrow aspiration in patients with pancytopenia on peripheral smear examination. Bone marrow aspiration was performed in 103 cases with pancytopenia over a period of 2 years. Bone marrow was hypercellular in 46.6%...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 50-year-old woman presented with fever for 1 week, with mild splenomegaly and anemia. Hematological examination showed pancytopenia, but peripheral blood smear examination showed no evidence of parasite. Because of pan-cytopenia, the patient was subjected ...

Gelatinous bone marrow transformation (GMT), also known as starvation marrow, represents a rare pathological entity of unclear etiology, in which bone marrow histopathology demonstrates hypoplasia, fat atrophy, and gelatinous infiltration. The finding of gelatinous marrow transformation lacks disease specificity; rather, it is an indicator of severe illness and a marker of poor nutritional stat...

Incidence and prevalence of Mycobacterium fortuitum infection vary greatly by location and death is very rare except in disseminated disease in immunocompromised individuals. We present what we believe is the first case of bone marrow infection with Mycobacterium fortuitum in an HIV negative patient. Bone marrow examination revealed presence of numerous acid fast bacilli which were confirmed as...

We hereby report a 79-year-old Iranian man presenting with nail dystrophy and subsequent development of purpuric and ecchymotic plaques, hemorrhagic bullae, and infiltrated papules on the head, neck and trunk. Histological examination of the gingiva, bone marrow aspiration, and biopsy confirmed the diagnosis of primary systemic amyloidosis. In this case, nail dystrophy was the presenting sign o...

Multiple myeloma (MM) is a clonal B-lymphocyte neoplasm of terminally differentiated plasma cells. Imaging modalities which allow the recognition of the effects of myeloma cells on the skeletal system have been utilized for a long time. Herein, we represent a patient with generalized osteoporosis and hypercalcemia, who was referred for parathyroid scan, in whom the widespread bone marrow techne...

Evidence is presented that at least 17% of microscopically normal bone marrow samples obtained from patients with undifferentiated lymphomas contain occult tumor cells. Of 19 microscopically normal bone marrow samples tested, continuous tumor cell lines were obtained from 4. A tumor cell origin was confirmed by the presence of an 8;14 chromosomal translocation in each case, and HLA typing confi...
