BACKGROUND: Besides peripheral cytopenias, bone marrow abnormalities, such as fibrosis, pure red cell aplasia, and aplastic anemia have been reported in patients with systemic lupus erythematosus (SLE), suggesting that bone marrow may be a target organ in SLE. Our objective was to describe this bone marrow involvement. METHODS: This registry is a nationwide retrospective study. Centers provided data concerning medical history, SLE manifestations, type of hematologic disorder, treatments and outcome...

Congenital pure erythroid leukemia is exceedingly rare and poses a diagnostic challenge. We report an atypical case of congenital pure erythroid leukemia that did not express typical erythroid markers. The patient presented with a high white blood cell count with blastic cells at birth. Although flow cytometric analyses of peripheral blood and bone marrow showed a large CD45-negative cell population, we did not identify any evidence of monoclonality. While the circulating blasts decreased with only supportive care, hepatomegaly with multiple nodules was accompanied by liver failure, disseminated intravascular coagulation, and development of hemophagocytic lymphohistiocytosis...

BACKGROUND: Although recombinant interferon-α (rIFNα) effectively treats patients with early myelofibrosis, the effect of driver and high molecular risk (HMR) mutations has not been considered. In this phase 2 study, for the first time, the authors correlate response to rIFNα treatment with driver and HMR mutations. METHODS: Patients were diagnosed using World Health Organization or International Working Group for Myeloproliferative Neoplasms Research and Treatment criteria...

Human parvovirus (HPV) B19 is linked to a variety of clinical manifestations, such as erythema infectiosum, nonimmune hydrops fetalis, and transient aplastic anemia. Although a few cases have shown HPVB19 infection as a possible causative agent for hepatitis-associated aplastic anemia (HAAA) in immunocompetent patients, most reported cases of HAAA following transient hepatitis did not have delayed remission. Here we report a rare case of severe aplastic anemia following acute hepatitis with prolonged jaundice due to HPVB19 infection in a previously healthy young male...

OBJECTIVES: We report a case of hairy cell leukemia (HCL) initially misdiagnosed as plasma cell dyscrasia due to various clinical, morphological and immunophenotypic confounders. METHODS AND RESULTS: In a patient diagnosed of marrow plasmacytosis and serum monoclonal protein elsewhere and referred to our hospital, morphological evaluation of bone marrow aspirate smears and trephine biopsy, immunophenotyping, and molecular testing (BRAFV600E mutation) were done. Clinically, the patient was asymptomatic; bone marrow revealed plasmacytosis, mastocytosis, and lymphocytosis with a few "hairy" cells...

Myeloma cast nephropathy is a major complication of multiple myeloma. Recent evidence has demonstrated that the earlier induction of bortezomib-based chemotherapy with plasma exchange (PE) provides better results for kidney function and patient survival. Due to its non-selectivity, PE with albumin replacement carries the risk of fibrinogen loss, leading to bleeding. We herein report a case of successful treatment of myeloma cast nephropathy using bortezomib-based chemotherapy and selective PE. A 61-year-old woman who had a 20-year history of type II diabetes mellitus was admitted to our hospital for the evaluation of hypercalcemia, severe kidney dysfunction, and anemia...

Sarcoidosis is a multiorgan inflammatory disease that rarely involves the musculoskeletal system. A typical radiographic presentation is only noted with phalangeal lesions in the hands and feet, and other skeletal sites of sarcoidosis are a diagnostic imaging challenge [1]. We describe two cases of patients with sarcoidosis in whom pathologic bone marrow lesions were diagnosed on MRI scans. The magnetic resonance findings were non-specific and metastatic lesions or multiple myeloma were suspected. The case analysis serves to point to limitations of imaging studies in diagnosing bone sarcoidosis and underline the importance of cooperation between the radiologist and the clinician...

Although epitrochlear lymph nodes may be enlarged as a part of generalized lymphadenopathy, isolated enlargement of epitrochlear lymph nodes is rarely seen. We describe Hodgkin's lymphoma in a 55-year-old male who presented with isolated epitrochlear lymphadenopathy of his right arm. In the histopathological examination of the epitrochlear lymph node was a lymphocyte-rich Hodgkin lymphoma with a clinical grade (CS IA) diagnosed. The diagnosis was confirmed, via the bone marrow biopsy and positron emission tomography/computed tomography imaging, as pathological stage PS IA and clinical stage CS IA...

The significance of upper gastrointestinal tract (UGI) acute GVHD (aGVHD) compared with other grade II aGVHD is not clearly defined. We compared the outcomes of patients with grade II aGVHD with or without biopsy-proven UGI involvement in three groups: grade II aGVHD without UGI (n=178), grade II aGVHD with UGI and other sites (n=102) and isolated UGI aGVHD (n=32). The overall response (ORR) to steroids at day 28 differed among the three groups (76, 67 and 91%, respectively, P=0.01), but was only marginally different in direct comparison with those without or with UGI aGVHD (P=0...

Multiple myeloma is a neoplastic proliferation of monoclonal plasma cells. Although it is usually restricted to the bone marrow, extraskeletal spread in the form of localised extramedullary collections of malignant plasma cells (plasmacytomas) can occur. However, gastrointestinal tract involvement in multiple myeloma is rare and overt gastrointestinal bleeding from plasmacytoma is uncommon. We report a case of colonic plasmacytoma which presented with bleeding per rectum and was initially misdiagnosed as colonic neuroendocrine carcinoma...

A 64-year-old woman was diagnosed to have refractory cytopenia with multilineage dysplasia (RCMD) including an increased number of sideroblasts in the bone marrow (BM). Computed tomography (CT) revealed a presacral mass which showed iso- or high-intensity signals according to T1-weighted and hypo-intensity signals on T2-weighted magnetic resonance imaging (MRI). CT-guided biopsy revealed the presence of hematopoietic tissue with features that correlated with the BM findings. While the formation of extramedullary hematopoiesis in the presacral area is rare, it is important to differentiate it from other parasacral tumors even though such differentiation is often difficult...

Bone metastasis from primary cancer sites creates diagnostic and therapeutic challenges. Calcified bone is difficult to biopsy due to tissue hardness and patient discomfort, thus limiting the frequency and availability of bone/bone marrow biopsy material for molecular profiling. In addition, bony tissue must be demineralized (decalcified) prior to histomorphologic analysis. Decalcification processes rely on three main principles: (a) solubility of calcium salts in an acid, such as formic or nitric acid; (b) calcium chelation with ethylenediaminetetraacetic acid (EDTA); or (c) ion-exchange resins in a weak acid...

BACKGROUND: Sjögren's syndrome is a chronic systemic disease, characterized by lymphocytic infiltration and destruction mainly of the salivary and lacrimal glands, resulting in xerostomia and xeropthalmia. Sjögren's syndrome patients have a 44-fold excess risk for the development of non-Hodgkin's lymphoma particularly mucosa-associated lymphoid tissue (MALT) lymphoma, prevalently affecting the major salivary glands. In this report, a rare case of MALT lymphoma of minor salivary glands in a patient with Sjögren's syndrome is described...

We report a case of May-Hegglin anomaly (MHA) in a woman who had a successful labor and delivery under epidural anesthesia. MHA is an inherited thrombocytopenia easily misdiagnosed as idiopathic (immune) thrombocytopenic purpura (ITP). Early and appropriate diagnosis of MHA during pregnancy is essential for optimal maternal and neonatal delivery outcome. Additionally, it can avoid unnecessary diagnostic studies, such as bone marrow aspiration and biopsy, and even harmful therapies with corticosteroids, immunosuppressive agents, and splenectomy...

The requirement for bone-marrow aspirates for genomic profiling of multiple myeloma poses an obstacle to enrolment and retention of patients in clinical trials. We evaluated whether circulating cell-free DNA (cfDNA) analysis is comparable to molecular profiling of myeloma using bone-marrow tumour cells. We report here a hybrid-capture-based Liquid Biopsy Sequencing (LB-Seq) method used to sequence all protein-coding exons of KRAS, NRAS, BRAF, EGFR and PIK3CA in 64 cfDNA specimens from 53 myeloma patients to >20,000 × median coverage...

Acute lymphoblastic leukaemia (ALL) is rarely seen in pregnancy. Massive hepatosplenomegaly as a presentation of ALL has not been described previously in any patient population. A 30-year-old pregnant woman presented at 16 weeks' gestation with epistaxis, jaundice, diffuse abdominal pain and distension, massive hepatosplenomegaly and peripheral oedema. On the basis of blood tests, bone marrow biopsy and imaging, a diagnosis of ALL complicated by massive hepatosplenomegaly with splenic infarctions was made. The patient was referred to oncology for appropriate chemotherapy...

RATIONALE: Intravascular large B-cell lymphoma (IVLBCL) is an extremely rare subtype of large B-cell lymphoma characterized by the presence of lymphoma cells within the lumen of small blood vessels. IVLBCL presents with nonspecific symptoms such as fever, weight loss, and bleeding. Because of its rarity and unremarkable clinical presentation, a timely diagnosis is very challenging. PATIENT CONCERNS: A 71-year-old Korean man complained of fever, but apart from pretibial pitting edema and mild thrombocytopenia, the physical examination and laboratory test findings were unremarkable...
