Mediastinal Myeloid Sarcoma is a rare entity. Here we present case of 28-year-old gentleman, who first presented with mediastinal mass and was clinically considered lymphoblastic lymphoma. He diagnosed initially as having T lymphoma on trucut biopsy. After one month patient Acute myeloid leukemia peripheral smear bone marrow examination confirmed the help flow cytometry. The biopsy slides from ...

Myeloid/lymphoid neoplasm is a rare malignancy with an aggressive course and rapid transformation to acute myeloid leukemia (AML), or less frequently lymphoblastic (ALL). Cases t(8;22)(p11;q11) BCR-FGFR1 fusion gene may be misdiagnosed chronic (CML), due very similar morphologic clinical profile. We report case of 48-year-old woman who complained weakness gastric pain. She had splenomegaly, eos...

calcium metabolic disorders, such as hypercalcemia is a potentially life-threatening disorder especially when coupled with an already compromised condition. the aim of this study was to determine the prevalence of metabolic calcium disorders in childhood cancers of patients admitted to the pediatric ward of vali-asr hospital from the year 2001-2008. the study was carried out by reviewing hospit...

The transcription factor PAX5 is a critical regulator of B-cell commitment and development. Although normally not expressed in myeloid progenitors, PAX5 has recently been shown to be frequently expressed in myeloid malignancies and to suppress expression of myeloid differentiation genes, compatible with an effect on the differentiation or maintenance of myeloid progenitors. However, previous st...

Hypoxia inducible factors (HIFs) are ubiquitously expressed transcription factors important for cell homeostasis during dynamic oxygen levels. Myeloid specific HIFs are crucial for aspects of myeloid cell function, including their ability to migrate into inflamed tissues during autoimmune disease. This contrasts with the concept that accumulation of myeloid cells at ischemic and hypoxic sites r...

Over the years a wealth of information on the role played by transcription factors in myeloid biology has contributed to our understanding of both normal and abnormal myeloid development. However, the regulation of mRNA translation in myeloid cell maturation has, in comparison, been a neglected area of study. A better understanding of the translational control of myeloid gene expression will un...

BACKGROUND Acute myeloid leukemia is typically a disease of the older population and presents mostly in the fifth decade of life. Myeloid sarcoma is a rare initial presentation of acute myeloid leukemia. Previously it has only been documented in children and younger patients. CASE PRESENTATION We present an unusual case of retro-orbital myeloid sarcoma as an initial presentation of acute myel...

Myeloid sarcoma is an extramedullary tumor of malignant myeloid cells often associated with acute myeloid leukemia, chronic myeloproliferative disorders and myelodysplastic syndromes. The skin is one of the most commonly affected sites. We report a rare case of cutaneous myeloid sarcoma associated with chronic myeloid leukemia.
