These include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). The majority of MPN result from somatic mutations in the 3 driver genes, JAK2, CALR, and MPL, which represent major diagnostic criteria in combination with hematologic and morphological abnormalities (Rumi & Cazzola, 2017).

The Association of Bladder Myeloid Sarcoma and Unclassified

We report a 71-year-old man with hematuria who had a diffuse myeloid sarcoma of the bladder. He was also under follow-up for unclassified myeloproliferative/myelodysplastic disorder, diagnosed two months before. Abdominal ultrasonography and computed tomography findings were normal. Diagnostic cystoscopy revealed patchy areas of mucosal swelling with hyperemia. Histopathological examination of biopsies demon- strated a neoplasm composed of blasts showing myeloperoxidase positivity by immunohistochemistry. To our knowledge, the current case is the first case of myeloid sarcoma in the urinary bladder without evidence of a mass lesion, with a concurrent diagnosis of unclassifiable myelodysplastic/myeloproliferative disease.

Primary myelofibrosis (formerly known as chronic idiopathic myelofibrosis), has the lowest incidence amongst the chronic myeloproliferative neoplasms and is characterized by a rather short median survival and a risk of progression to acute myeloid leukemia (AML) noted in a small subset of the cases, usually as a terminal event. As observed with other chronic myeloproliferative neoplasms, the bone marrow biopsy may harbor small lymphoid aggregates, often assumed reactive in nature. In our paper, we present a 70-year-old Caucasian male who was diagnosed with primary myelofibrosis, and after 8 years of followup and therapy developed an AML. -

We studied 879 PMF patients to determine the individual and combinatorial prognostic relevance of somatic mutations. Analysis was performed in 483 European patients and the seminal observations were validated in 396 Mayo Clinic patients. Samples from the European cohort, collected at time of diagnosis, were analyzed for mutations in ASXL1, SRSF2, EZH2, TET2, DNMT3A, CBL, IDH1, IDH2, MPL and JAK2. Of these, ASXL1, SRSF2 and EZH2 mutations inter-independently predicted shortened survival. However, only ASXL1 mutations (HR: 2.02; Po0.001) remained significant in the context of the International Prognostic Scoring System (IPSS). These observations were validated in the Mayo Clinic cohort where mutation and survival analyses were performed from time of referral. ASXL1, SRSF2 and EZH2 mutations were independently associated with poor survival, but only ASXL1 mutations held their prognostic relevance (HR: 1.4; P ¼ 0.04) independent of the Dynamic IPSS (DIPSS)-plus model, which incorporates cytogenetic risk. In the European cohort, leukemia-free survival was negatively affected by IDH1/2, SRSF2 and ASXL1 mutations and in the Mayo cohort by IDH1 and SRSF2 mutations. -

Acute myelofibrosis in patients with acute lymphoblastic leukemia is extremely rare. We report a 4-year-old boy who was diagnosed as having acute massive myelofibrosis and acute lym- phoblastic leukemia. Performing bone marrow aspiration in this patient was difficult (a “dry tap”), and the diagnosis was established by means of a bone marrow biopsy and immunohistopathologic analysis. The prognostic significance of acute myelofibrosis in patients with acute lymphoblastic leukemia is not clear.

Introduction Myelofibrosis (MF) is one of the chronic Philadelphia chromosome– negative myeloproliferative neoplasms (MPNs). It is characterized by the clonal proliferation of myeloid cells, leading to extramedullary hematopoiesis, hepatosplenomegaly, constitutional symptoms (ie, fatigue, night sweats, weight loss, and fever), and cytopenia, along with bone marrow fibrosis and an increased risk for evolution into acute myeloid leukemia (AML). -

Andrews, MD, DM. eurological manifestations of acute leukemia are Ndue to direct involvement by meningeal infiltration and myeloid sarcoma; and indirect involvement by immunosuppression and treatment related side effects. It is rare for myeloid sarcoma to present without bone marrow involvement (isolated myeloid sarcoma or primary granulocytic sarcoma).1 It is even rarer for an isolated myeloid sarcoma to present in the epidural space. We evaluated a case of paraplegia admitted to our department. He had several atypical features that we would like to present in this report.

The similarities between these two conditions in terms of clinical presentation and morphology can really create a diagnostic dilemma. Here we present a case of Chronic myeloid leukemia in fi brosis and blast crisis in a 32 year old lady which closely resembled Primary myelofi brosis in transformation. All myeloproliferative neoplasms can undergo blast transformation. In this case, the detection of Philadelphia chromosome helped to distinguish Chronic myeloid leukemia from other myeloproliferative neoplasms.
