Introduction Myeloid sarcoma (previously chloroma or granulocytic sarcoma) is a very rare malignant neoplasm associated with myeloproliferative neoplasms. This type of tumour can be located anywhere outside the bone marrow. Aim To describe successful treatment and diagnostic myeloid sarcoma. Case study Retrospective case review. Results discussion paper presents in 50-year-old male. Patient pre...

Materials and Methods: BMA and BMB were performed on 50 patients. Criteria of inclusion included the main indications for performing this procedure, the availability of full medical records and patient consent. The patients had a male to female sex ratio of 1.6:1 and a wide age range from 4 years to 74 years. Results: In the present study, the main indications for bone marrow examination were c...

The prognostic heterogeneity of the World Health Organization category of "systemic mastocytosis with associated clonal hematologic nonmast cell lineage disease" (SM-AHNMD) has not been systematically validated by primary data. Among 138 consecutive cases with SM-AHNMD, 123 (89%) had associated myeloid neoplasm: 55 (45%) myeloproliferative neoplasm (SM-MPN), 36 (29%) chronic myelomonocytic leuk...

Various translocations involving the PDGFRB gene are identified in myeloid neoplasms. However, the PRKG2/PDGFRB fusion gene associated with t(4;5)(q21;q33) has previously been reported in only 3 patients. We present the case of a 26-year-old woman with microcytic anemia, basophilia, thrombocytosis, and massive splenomegaly, who was found to have systemic mastocytosis and associated clonal hemat...

To the Editor, Extramedullary hematopoiesis (EMH) is the presence of hemopoietic precursors outside the bone marrow. Usually, it is noted in patients with myeloproliferative disorder and congenital hematological diseases. The organs most commonly involved are the spleen, liver, and lymph nodes, but EMH has also been reported in a number of unusual sites such as, mediastinum and even breast. Alt...

Dear Editor, Translocation t(8;9)(p22;p24) has been reported in diverse hematologic neoplasms, including acute leukemia, myeloproliferative neoplasm (MPN), and myelodysplastic syndromes/myeloproliferative neoplasm. These findings indicate that the mutation occurs in pluripotent, lymphoid-myeloid stem cells [1]. The pericentriolar material 1 (PCM1) gene, located on chromosome 8p22, encodes a pro...
