An acquired coagulation factor deficiency is characterized by acquired autoantibodies against specific clotting factors in those without diagnosed hemophilia. It is a relatively rare condition with an incidence of approximately one case per million per year. We present a case report of an elderly male who initially presented with an occult GI bleed that was identified with a positive fecal occult blood test result. This is the first case reported to our knowledge of an acquired factor inhibitor deficiency presenting in this manner...

Christopher A Willner, Mohammed M Chisti
The development of a heparin-like anticoagulant (HLAC) in plasma cell neoplasia has previously been described in clinical literature. Testing of this HLAC, primarily in vitro, has demonstrated that neutralization may be achieved with protamine sulfate, owing to antithrombin III cofactor activity. We report a case in which intravenous protamine sulfate was administered to a patient with IgG-kappa monotypic multiple myeloma, which resulted in resolution of bleeding and coagulopathy, confirmed via objective laboratory data...

Anaplastic lymphoma kinase-positive large B-cell lymphoma (ALK+ LBCL) is a very rare and aggressive subtype of diffuse large B-cell lymphoma characterized by ALK rearrangement. Immunophenotypically, the tumor cells are typically negative for common B-cell markers, T-cell markers, and CD30; however, they express markers of terminally differentiated B cells/plasma cells such as CD38, CD138, and MUM-1/IRF4. The diagnosis of ALK+ LBCL can be challenging, and often a large panel of immunostains is required to exclude other hematopoietic and nonhematopoietic neoplasms...

A 41-year-old man with newly diagnosed acute promyelocytic leukemia (APL) received induction chemotherapy, containing all- trans retinoic acid (ATRA), idarubicin, and arsenic trioxide. On the 11th day of therapy, he experienced complete atrioventricular (AV) block; therefore, ATRA and arsenic trioxide were immediately postponed. His heart rate partially recovered, and ATRA was rechallenged with a half dose. However, complete AV block as well as differentiation syndrome recurred on the next day. ATRA was immediately discontinued, and a temporary pacemaker was inserted...

Multiple myeloma is a malignant clonal proliferation of plasma cells in the bone marrow preceded by monoclonal gammopathy of undetermined significance. Initial presentation of multiple myeloma as extramedullary spread in soft tissues particularly in the liver is uncommon. We report a case of a 74-year-old African American female who presented with epigastric pain, hematemesis, elevated alkaline phosphatase, and gamma-glutamyl transferase. Initial impression was peptic ulcer disease; however, ultrasound and CT scan of the abdomen showed multiple liver nodules and perihepatic lymphadenopathy suggestive of metastatic disease...

Early-stage chronic lymphocytic leukemia (CLL) with neurologic involvement is a rare condition and should require a careful follow-up. Although no standard protocol exists for this condition, intrathecal chemotherapy, combined with systemic chemoimmunotherapy, has been used previously. This case describes the treatment of a patient with CLL and symptomatic compromise of the central nervous system. Our results suggest that a combination of chemotherapy, radiotherapy, and ibrutinib, administered sequentially over a 2-year period, led to a near-complete resolution of the cerebral spinal fluid neoplastic infiltration...

Thrombocytopenia is defined as a condition where the platelet count is below the lower limit of normal (<150 G/L), and it is categorized as mild (100-149 G/L), moderate (50-99 G/L), and severe (<50 G/L). We present here a 79-year-old man who developed severe thrombocytopenia with a platelet count of 6 G/L, less than 24 hours after intravenous tirofiban infusion that was given to the patient during a percutaneous transluminal coronary angioplasty procedure with placement of 3 drug-eluting stents...

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocyte disorder most commonly characterized by multifocal osteosclerotic lesions of the long bones demonstrating sheets of foamy histiocyte infiltrates on biopsy with or without histiocytic infiltration of extraskeletal tissues. ECD can be difficult to diagnose since it is a very rare disease that can affect many organ systems. Diagnosis is based on the pathologic evaluation of involved tissue interpreted within the clinical context. Patients who have the BRAF V600E mutation are treated first line with vemurafenib...

Great strides have been made in the treatment of acute myeloid leukemia (AML) resulting in increased number of survivors over all age groups, but especially in patients of reproductive age. Given the gonadotoxicity of high-dose induction chemotherapy and subsequent allogeneic stem cell transplant, it is paramount that fertility preservation options are discussed and explored at the time of diagnosis as fertility preservation has been associated with greater quality of life in survivors. Starting the conversation early is especially important for female patients given the time needed for all currently available fertility preservation techniques...

Although transformation of the myeloproliferative neoplasms (MPNs) to acute myeloid leukemia (AML) is well documented, development of an MPN in patients previously treated for, and in remission from, AML is exceedingly rare. A case is described in which a patient was successfully treated for AML and in whom a JAK2 V617F-positive MPN was diagnosed after seven years in remission. Retrospective evaluation of the JAK2 V617F detected a low allele burden at AML diagnosis and following one course of induction chemotherapy...

We report the case of a 73-year-old male with primary myeloid sarcoma (MS) of the prostate. He underwent remission-induction chemotherapy followed by conventional consolidation for acute myeloid leukemia (AML). One year after initial diagnosis, he was without evidence of AML, the longest reported period of time in the literature for a case of primary MS of the prostate. From 1985 to 2017, fifteen other cases of MS of the prostate have been reported and are reviewed here. Five cases occurred as primary MS, without evidence of AML on bone marrow examination or prior history of hematologic disorders, and progressed to AML within a range of three weeks to seven months...

Rhabdomyolysis is a life-threatening syndrome due to breakdown of the skeletal muscle. It can be caused by massive trauma and crush injuries or occur as a side effect of medications. Here, we describe a case of a 33-year-old male with human immunodeficiency virus (HIV) and newly diagnosed chronic myeloid leukemia (CML) with severe life-threatening rhabdomyolysis due to a rare offending agent.

Rosai-Dorfman disease (RDD) is a rare, nonmalignant disorder of histiocyte proliferation typically involving the cervical lymph nodes. However, a subset of patients with RDD will display extranodal manifestations that are highly variable in presentation, more challenging to diagnose, and less likely to spontaneously regress compared to nodal disease. While case reports of extranodal involvement in nearly every organ system exist, documented instances of mediastinal and pulmonary artery involvement are particularly rare...

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disorder that can be familial in etiology or a result of infections, malignancy, and autoimmune or inflammatory disorders. Disseminated intravascular coagulation (DIC) is common in patients admitted to intensive care units and can confound and delay the diagnosis of HLH. We present a case of a 69-year-old female who presented with dyspnea and malaise. Her condition declined rapidly with laboratory parameters consistent with DIC. In addition, she had a ferritin of 32,522 ng/mL, low haptoglobin, and elevated LDH, and bone marrow biopsy showed hemophagocytic lymphohistiocytes...

A 47-year-old male presented with a groin lesion in 2011. Initial treatment with antifungals and vinegar was unsuccessful. In 2016, biopsy of this lesion was pursued with diagnosis of extramammary Paget's disease (EMPD). Prior to the scheduled excision, he developed constant lower back pain with radiation to his lower extremities. MRI confirmed vertebral metastasis. Despite surgical and radiation therapy, his back pain progressed, and repeat imaging showed epidural spread of tumor in the thoracic spine. Later, the patient was admitted to the hospital due to severe anemia and thrombocytopenia...

Catastrophic antiphospholipid syndrome is a rare condition with high morbidity and mortality. We present a refractory case of catastrophic antiphospholipid syndrome with a view to highlight the importance of early identification and aggressive treatment of this condition. A 36-year-old female presented with clinical manifestations of multiorgan vascular occlusion with a known history of primary antiphospholipid syndrome. The presentation was on a background of a recent change of her long-term anticoagulation from warfarin to therapeutic low-molecular-weight heparin...

Lenalidomide maintenance following autologous stem cell transplant (ASCT) is considered the standard of care for eligible patients with multiple myeloma (MM). A recent meta-analysis has provided additional evidence that lenalidomide maintenance is associated with a higher incidence of second primary malignancies, including both hematologic and solid malignancies. Acute lymphoblastic leukemia (ALL) as a second primary malignancy is rarely described in the literature. Herein, we describe two patients with MM treated with induction therapy, ASCT, and lenalidomide maintenance that experienced cytopenias while on maintenance...

Kikuchi-Fujimoto disease (KFD) or histiocytic necrotizing lymphadenitis is a rare disease that is frequently underdiagnosed due to clinical features that are similar to those of non-Hodgkin lymphomas, systemic lupus erythematosus (SLE), or infectious reactive lymphadenopathy. An excisional biopsy is required. We report a young Caucasian female diagnosed with KFD with skin lesions, complicating with SLE. The clinical course, laboratory, and CT findings are described, as are histopathologic features, for a better recognition of this rare disorder in clinical practice...

Jason N Barreto, Allison L McClanahan, Andrew D Rule, Carrie A Thompson, Erin Frazee
High-dose methotrexate (MTX; ≥1 g/m2 ) is a renally eliminated and nephrotoxic first-line therapy for central nervous system (CNS) lymphoma. Creatinine-based estimation of renal function is the recommended approach to dosing MTX in these cases, but nonrenal determinants of creatinine production and elimination in cancer patients such as malnutrition and cachexia lead to overestimation of glomerular filtration rate (GFR) by this method and a heightened risk for drug toxicity. Serum cystatin C is one of the first readily available, relatively inexpensive, endogenous biomarkers to emerge as a practical adjunct to creatinine for estimation of renal function for drug dosing...

Invasive fungal infections bring serious mortality and morbidity during the treatment of acute myeloid leukemia. Especially, mold infections are challenging, and each case is unique in feature. These cases are usually fatal, and there is no consensus regarding optimal treatment. AML patients receive antifungal prophylaxis and may further require IFI (invasive fungal infection) treatments, but fusarium mold infections are often unrecognized and could be overlooked. In this case report, we try to emphasize the importance of this infection with a high-risk AML patient...
