This review reflects the trajectory of my career in hematopathology, and my personal reflections on scientific advances in the field. During the course of more than 40 years, the approach to classification of hematological malignancies has evolved from descriptive approaches, based on either cytological or clinical features, to a modern approach, which incorporates cutting-edge technologies. My philosophy has focused on defining individual diseases, an approach that can best lead to an understanding of molecular pathogenesis...

In the past accurate diagnosis of lymphoma was challenging since there were multiple competing classification systems which caused confusion and debate. After the World Health Organization lymphoma classification lymphomas still remain a diagnostic challenge among general pathologists. Purpose of this study was to examine whether the discordance among centers has declined throughout the years. All lymphoma or lymphoma suspected specimens,that had been referred to the Cerrahpasa Medical Faculty between 2000-2013 for a second opinion were deemed eligible...

Since 2012, a number of case reports have described the occurrence of thrombotic microangiopathy (TMA) following intravenous abuse of extended release oxymorphone hydrochloride (Opana ER), an oral opioid for long-term treatment of chronic pain. Here, we present unique clinical features of three patients and investigate intravenous exposure to the tablet's inert ingredients as a possible causal mechanism. Guinea pigs were used as an animal model to understand the hematopathologic and nephrotoxic potential of the inert ingredient mixture (termed here as PEO+) which primarily contains high molecular weight polyethylene oxide (HMW PEO)...

Hematological disorders like myelodysplastic syndrome (MDS) may arise due to cumulative dysregulation of various signalling pathways controlling proliferation, differentiation, maturation and apoptosis of bone marrow cells. This devastating bone marrow condition can be due to consequential abnormalities in haematopoiesis as well as its supportive microenvironment. Although mutations related to JAK/STAT pathway are common in myeloproliferative neoplasms, further studies are required to fully explore the myelodysplastic scenario regarding the concerned pathway...

Plasma cell leukemia (PCL) is a rare and aggressive variant of myeloma accounting for 2-3% of all plasma cell dyscrasias characterized by the presence of circulating plasma cells. The diagnosis is based on the % (≥20%) and absolute number (≥2x10 9 /L) of plasma cells in the peripheral blood. The incidence of primary PCL (pPCL) is very rare and reported to occur in <1 in a million. It is classified as either pPCL occurring at diagnosis or as secondary PCL in patients with relapsed/refractory myeloma. pPCL is a distinct clinicopathological entity with different cytogenetic and molecular findings...

BACKGROUND: We have evaluated the frequency of lymphoproliferative disorders with more than one aberrant population of monotypic B-cells detected during routine hematopathological diagnostics. MATERIALS AND METHODS: 2600 samples peripheral (blood, bone marrow, fine needle aspirate, lymph node and pleural fluid cell suspensions) were analyzed using a ten-color B-cell panel and a ten-color T-cell panel. A ten-color plasma cell/lymphoplasmacytic panel was performed when appropriate...

OBJECTIVES: The biannual Fellow In-Service Hematopathology Examination (FISHE) assesses knowledge in five content areas. We examined the relationship between taking the FISHE and performance on it with outcomes on the first attempted American Board of Pathology Hematology subspecialty certifying examination (ABP-HE). METHODS: The pass rate between the ABP-HE candidates who took the spring FISHE and those who did not were compared. The likelihood of fellows passing the ABP-HE based on their percentiles on the FISHE was also assessed...

Small B cell lymphoid neoplasms are the most common lymphoproliferative disorders involving peripheral blood (PB) and bone marrow (BM). The Bone Marrow Workshop (BMW) organized by the European Bone Marrow Working Group (EBMWG) of the European Association for Haematopathology (EAHP) during the XVIIth EAHP Meeting in Istanbul, October 2014, was dedicated to discussion of cases illustrating how the recent advances in immunophenotyping, molecular techniques and cytogenetics provide better understanding and classification of these entities...

AIM: An experimental study was carried out on 148 naturally infected indigenous cattle breeds with either single or mix infections of various species of trypanosomes. The objectives of this study were to determine the species of trypanosomes, observe their hematopathological consequences on host-related risk factors and to determine the packed cell volume (PCV) of the infected group. MATERIALS AND METHODS: The buffy coat method (BCM) which is a variant of the hematocrit centrifugation method was used for the parasitological and hematological analysis...

Microscopic examination of myelodysplastic syndromes (MDS) and myelodysplastic-myeloproliferative neoplasms (MDS/MPN) may be challenging because morphological features can overlap with those of reactive states. Demonstration of clonal hematopoiesis provides a diagnostic clue and has become possible by comprehensive mutation profiling of a number of frequently mutated genes, some of them with large coding regions.To emphasize the potential benefit of NGS in hematopathology we present sequencing results from routinely processed formalin-fixed and paraffin-embedded (FFPE) bone marrow trephines (n = 192)...

Expression analyses suggest that alterations of the antioxidant state of some diffuse large B-cell lymphomas can assist prognosis; reversibly oxidized thiols may serve as a surrogate marker for identifying such cases. Little is known about the distribution of free thiols and reversibly oxidized thiols in human tissues. We developed a staining technique that enables visualization of tissue thiols in situ using bright field microscopy and validated it using gastrointestinal tissue specimens. We used our thiol staining technique to assess benign tonsillectomy and diffuse large B-cell lymphoma specimens...

Kaaren K Reichard, Adam J Wood
As the cost of health care continues to rise and reimbursement rates decrease, there is a growing demand and need to cut overall costs, enhance quality of services, and maintain as a top priority the needs and safety of the patient. In this article, we provide an introduction to test utilization and outline a general approach to creating an efficient, cost-effective test utilization strategy. We also present and discuss 2 test utilization algorithms that are evidence-based and may be of clinical utility as we move toward the future of doing the necessary tests at the right time...

CONTEXT: -There is ample evidence from the solid tumor literature that synoptic reporting improves accuracy and completeness of relevant data. No evidence-based guidelines currently exist for synoptic reporting for bone marrow samples. OBJECTIVE: -To develop evidence-based recommendations to standardize the basic components of a synoptic report template for bone marrow samples. DESIGN: -The College of American Pathologists Pathology and Laboratory Quality Center convened a panel of experts in hematopathology to develop recommendations...

BACKGROUND: The 2008 WHO is not specific regarding subclassification of chronic myelogenous leukemia (CML) with less than 20% abnormal B lymphoid blasts (ABLB), and suggests patients with ABLB often show rapid progression (Swerdlow, 2008). Recent studies have shown variable outcomes when small abnormal B cell populations are seen by flow cytometry (El Rassi et al., Cancer 2015; 121:872-875; Vrotsos et al., Cytometry B Clin Cytom 2015). METHODS: The hematopathology database was searched (7...

BACKGROUND: Systemic mastocytosis (SM) is a diagnosis made using clinical, laboratory, and histologic parameters. Aberrant CD2 and/or CD25 expression on mast cells provides one minor criterion for a diagnosis of SM. To validate a tube (CD45/CD117/CD2/CD25) for mast cell evaluation, flow cytometry (FC) on residual material from marrow aspirates samples submitted to the hematopathology laboratory was performed. METHODS: Samples evaluated (n = 98) had no clinical or morphologic suspicion for SM...
