A 15-year-old, female Vieilott's fireback pheasant (Lophura rufa) presented with a 2-day history of a drooping right wing. Examination revealed severe soft tissue swelling in the area extending from the right shoulder to the humeral-radio-ulnar joint with associated bruising and feather loss. Results of a complete blood cell count revealed marked heterophilia and lymphocytosis, and results of serum biochemical analysis showed severe increases in creatine kinase and aspartate aminotransferase activities, hypoproteinemia, and hypoalbuminemia...

Adult T-cell leukemia/lymphoma belongs to the group of mature T-cell malignancies according to the WHO classification. It constitutes a rare entity and has a strong association with infection by human T-lymphotropic virus 1. In Uruguay, this viral infection is very infrequent and, to our knowledge, no case of adult T-cell leukemia/lymphoma has been previously reported. We describe the case of a woman, immigrant from Peru, who presented with persistent lymphocytosis, intestinal parasitic diseases, and skin involvement...

Decreased absolute lymphocyte counts (ALCs) following frontline therapy for chronic lymphocytic leukemia may be associated with disease control, even in patients without evidence of minimal residual disease. We studied the prognostic significance of ALCs during the first year following treatment with fludarabine, cyclophosphamide, and rituximab (FCR). We evaluated 99 patients who achieved a partial response without lymphocytosis (<4.0 × 10(3) cells/μL) or better after FCR. Absolute lymphocyte counts were recorded at 3-, 6-, 9-, and 12-month posttreatment and correlated with overall survival (OS) and event-free survival (EFS)...

BACKGROUND: Sarcoidosis is a systemic granulomatous disease of unknown etiology. Epidemiological studies of different populations are essential because clinical presentation, organ involvement, disease severity, and prognosis vary significantly according to region and population. The aim of this study was to assess epidemiological and clinical characteristics, staging factors, and clinical course in patients with sarcoidosis from a tertiary hospital in Oporto, Portugal. METHODS: A retrospective analysis of patients with sarcoidosis and at least 2 years of follow-up evaluated at the Centro Hospitalar de São João between 2000 and 2014...

BACKGROUND: We present a case of gamma-delta T-cell lymphoma that does not fit the current World Health Organization classifications. CASE PRESENTATION: A 74-year-old Caribbean-American woman presented with lymphocytosis, pruritus, and non-drenching night sweats. Bone marrow and peripheral blood analyses both confirmed the diagnosis of gamma-delta T-cell lymphoma. An axillary lymph node biopsy was negative for lymphoma. Clinically absent hepatosplenomegaly and skin lesions with biopsy-proven gamma-delta T-cell lymphoma suggest that she is unclassifiable within the current classification system...

Vasileios Kouranos, Joseph Jacob, Andrew Nicholson, Elizabetta Renzoni
The diagnosis of hypersensitivity pneumonitis (HP) relies on the clinical evaluation of a number of features, including a history of significant exposure to potentially causative antigens, physical examination, chest CT scan appearances, bronchoalveolar lavage lymphocytosis, and, in selected cases, histology. The presence of fibrosis is associated with higher morbidity and mortality. Differentiating fibrotic HP from the idiopathic interstitial pneumonias can be a challenge. Furthermore, even in the context of a clear diagnosis of fibrotic HP, the disease behaviour can parallel that of idiopathic pulmonary fibrosis in a subgroup, with inexorable progression despite treatment...

Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of mature CD5+ B cells in blood. Spontaneous apoptosis of CLL cells in vitro has hampered in-depth investigation of CLL pathogenesis. Here we describe the generation of three monoclonal mouse cell lines, EMC2, EMC4 and EMC6, from the IgH.TEμ CLL mouse model based on sporadic expression of SV40 large T antigen. The cell lines exhibit a stable CD5+CD43+IgM+CD19+ CLL phenotype in culture and can be adoptively transferred into Rag1-/- mice...

Germline heterozygous gain-of-function (GOF) mutations of NFKBIA, encoding IκBα, cause an autosomal dominant (AD) form of anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID). Fourteen unrelated patients have been reported since the identification of the first case in 2003. All mutations enhanced the inhibitory activity of IκBα, by preventing its phosphorylation on serine 32 or 36 and its subsequent degradation. The mutation certainly or probably occurred de novo in 13 patients, whereas it was inherited from a parent with somatic mosaicism in one patient...

Proapoptotic Bcl-2 family member Bim is particularly relevant for deletion of autoreactive and activated T and B cells, implicating Bim in autoimmunity. As atherosclerosis is a chronic inflammatory process with features of autoimmune disease, we investigated the impact of hematopoietic Bim deficiency on plaque formation and parameters of plaque stability. Bim (-/-) or wild type bone marrow transplanted ldlr (-/-) mice were fed a Western type diet (WTD) for 5 or 10 weeks, after which they were immunophenotyped and atherosclerotic lesions were analyzed...

OBJECTIVES: Monoclonal B-cell lymphocytosis (MBL) is a precursor state of chronic lymphocytic leukemia (CLL) with peripheral lymphocytosis below 5 × 10(9)/l. The diagnostic criteria exclude the presence of lymphadenopathy, organomegaly, infections, autoimmune diseases or any sign of a lymphoproliferative disorder. This prospective study was designed in order to evaluate the frequency of MBL in blood donors in Turkey. METHODS: The diagnosis of MBL was identified by flow cytometry method based on the International Familial CLL Consortium Report...

Splenic marginal zone lymphoma (SMZL) is a low-grade B-cell non-Hodgkin's lymphoma characterized by massive splenomegaly, moderate lymphocytosis with or without villous lymphocytes, rare involvement of peripheral lymph nodes and indolent clinical course. As a rare disease, with no randomized prospective trials, there is no standard of care for SMZL so far. Splenectomy has been done for many years as an attempt to control disease, but nowadays it has not been encouraged as first line because of new advances in therapy as rituximab, that are as effective with minimal toxicity...

Bovine leukemia virus (BLV) infections, causing persistent lymphocytosis and lethal lymphosarcoma in cattle, have reached high endemicity on dairy farms. We observed extensive inter-individual variation in the level of infection (LI) by assessing differences in proviral load in peripheral blood. This phenotypic variation appears to be determined by host genetics variants, especially those located in the BoLA-DRB3 MHCII molecule. We performed an association study using sequencing-based typed BOLA-DRB3 alleles from over 800 Holstein and Holstein × Jersey cows considering LI in vivo and accounting for filial relationships...

Aggressive natural killer (NK)-cell leukemia/lymphoma is a systemic NK-cell neoplasm that preferentially affects Asians with a fulminant clinical course and is almost always associated with Epstein-Barr virus (EBV). The data on EBV-negative aggressive NK-cell leukemia/lymphoma are limited. Here we report a series of three patients (two Caucasians, one African-American) with EBV-negative aggressive NK-cell leukemia/lymphoma from a single institution, including a case diagnosed on post-mortem examination. Similar to EBV-positive aggressive NK-cell leukemia/lymphoma, our patients presented with constitutional symptoms and hepatosplenomegaly, and followed a highly aggressive clinical course...

Background: Meningioma is the most common primary intracranial tumor and recurrence is one of the important challenges in patient management. Prognostic factors for tumor recurrences in these patients especially before surgical resection are not fully characterized. Several studies have indicated an association between changes in hematologic laboratory parameters with patient outcomes in solid malignancies. We aimed to assess the association between hematological parameters and tumor recurrence in patients with meningioma...

Cigarette smoking is the most frequently encountered risk factor for chronic obstructive pulmonary disease and lung cancer. The latest American Thoracic Society÷European Respiratory Society classification of idiopathic interstitial pneumonia includes two entities related to smoking habits: respiratory bronchiolitis-associated interstitial lung disease and desquamative interstitial pneumonia. The new approach to diagnosis is to combine pathological pattern with clinical and radiological data. Lung biopsy is no longer considered the "gold standard" for diagnosis, but as a part of the diagnosis, which shall be set only after the pulmonologist, radiologist and pathologist reviewed all clinical, imaging and pathological aspects...

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...

Syndrome of transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis (HaNDL syndrome) is described as "headache attributed to noninfectious inflammatory disease" featuring, as its name suggests, headache that mimics migraine in addition to neurologic symptoms such as hemiparesis, hemiparesthesia and dysphagia. We report a case of a 50-year-old African-American female who presented with headache, malaise and subsequent hemiparesis. Despite bearing a close resemblance to an acute episode of meningitis clinically, cerebrospinal fluid (CSF) analysis of the patient was only positive for isolated elevation in white cell count...

We herein report a case of T-cell/histiocyte-rich large B-cell lymphoma which initially presented as a self-limiting T-lymphoproliferative disorder involving multiple extranodal and extrapulmonary organs, such as the salivary gland, the liver, and the central nervous system. Repeated biopsies only revealed polyclonal T-lymphocytosis without the presence of atypical B-cells. Angiocentric cellular infiltration was absent, thus ruling out lymphomatoid granulomatosis. A recurrence in the lymphatic system finally revealed a small population of pathognomonic atypical B-cells, which led to the diagnosis...
