“…Nodal EMH has been sporadically reported in people and animals as an incidental finding or associated with inherent hematologic disorders . To the best of our knowledge, this is the first cytologic report of EMH including all 3 hematopoietic lineages in the lymph node of a dog.…”

A B C Figure 1. Microscopic images of extramedullary hematopoiesis in a smear of a fine-needle aspirate from an enlarged lymph node in a dog with multicentric lymphoma, Hemacolor. (A) An elongated, dysplastic megakaryocyte with hypolobulation of the nucleus, surrounded by predominantly immature lymphocytes. The 2 largest cells with pale cytoplasm are presumptive myeloblasts (arrows). (B) A rubriblast (arrow) with a rim of intensely basophilic cytoplasm and a polychromatophilic rubricyte (arrowhead) are close to large lymphoid cells with very prominent nucleoli. (C) A promyelocyte (arrow) admixed with neoplastic lymphoid cells. Bar = 30 lm (A), 20 lm (B, C).

“…1 The diagnosis has been rendered by FNA in a variety of locations. 2,[7][8][9][10][11][12][13] There are two reports in the literature of a misdiagnosis of malignant cells in cases that were later proven to be EMH, emphasizing the pitfall that the large atypical cells seen in EMH (predominantly megakaryocytes, but also blasts) can mimic malignancy. 8,13 The differential diagnosis of a discrete mass-forming lesion in the spleen includes cyst, abscess, vascular tumors including hemangioma, Littoral cell angioma, epithelioid hemangioendothelioma, and angiosarcoma, large B-cell lymphoma, Hodgkin's lymphoma, and metastatic carcinoma.…”

Extramedullary hematopoiesis (EMH) is the production of mature blood elements outside of the bone marrow and can occur as a compensatory result of a marrow replacing process or from marrow space occupying lesions such as tumor or marrow fibrosis. EMH can also be induced by factors elicited by neoplasms, such as vascular endothelial growth factor (VEGF). Usually, EMH is a diffuse process most commonly observed in lymph nodes, liver, and spleen. Rarely, EMH can form a mass lesion. Although the spleen is a common site for diffuse EMH, it is a rare location for a mass forming EMH. Hemangiomas are the most common benign tumors of the spleen. A case of a discrete, 8 cm lesion was noted incidentally on CT scan in a 59-year-old man with no significant past medical history. Endoscopic ultrasound guided fine-needle aspiration (EUS FNA) biopsy was performed and cytologic examination revealed trilinear hematopoiesis, with the most distinctive elements being megakaryocytes and erythroid precursors. A diagnosis of EMH was made. On resection, the mass was a hemangioma with EMH. EUS guided FNA is a useful tool for diagnosing splenic masses. Awareness of EMH, both as a mass forming lesion and a feature associated with benign and malignant vascular lesions is important, especially in patients with hematologic malignancies or marrow replacing processes.

Authors attain comparable or slightly higher rates of citation publishing in an open access journal (CytoJournal) compared to traditional cytopathology journals - A five year (2007-2011) experience

Background:The era of Open Access (OA) publication, a platform which serves to better disseminate scientific knowledge, is upon us, as more OA journals are in existence than ever before. The idea that peer-reviewed OA publication leads to higher rates of citation has been put forth and shown to be true in several publications. This is a significant benefit to authors and is in addition to another relatively less obvious but highly critical component of the OA charter, i.e. retention of the copyright by the authors in the public domain. In this study, we analyzed the citation rates of OA and traditional non-OA publications specifically for authors in the field of cytopathology.Design:We compared the citation patterns for authors who had published in both OA and traditional non-OA peer-reviewed, scientific, cytopathology journals. Citations in an OA publication (CytoJournal) were analyzed comparatively with traditional non-OA cytopathology journals (Acta Cytologica, Cancer Cytopathology, Cytopathology, and Diagnostic Cytopathology) using the data from web of science citation analysis site (based on which the impact factors (IF) are calculated). After comparing citations per publication, as well as a time adjusted citation quotient (which takes into account the time since publication), we also analyzed the statistics after excluding the data for meeting abstracts.Results:Total 28 authors published 314 publications as articles and meeting abstracts (25 authors after excluding the abstracts). The rate of citation and time adjusted citation quotient were higher for OA in the group where abstracts were included (P < 0.05 for both). The rates were also slightly higher for OA than non-OA when the meeting abstracts were excluded, but the difference was statistically insignificant (P = 0.57 and P = 0.45).ConclusionWe observed that for the same author, the publications in the OA journal attained a higher rate of citation than the publications in the traditional non-OA journals in the field of cytopathology over a 5 year period (2007-2011). However, this increase was statistically insignificant if the meeting abstracts were excluded from the analysis. Overall, the rates of citation for OA and non-OA were slightly higher to comparable.
