Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...

Objective To discuss the clinical value of immunoglobulin gene rearrangements in the diagnosis of B-cell lymphoma. Methods A total of 209 cases of B-cell lymphomas and 35 cases of reactive lymphoid hyperplasia were selected for DNA extraction and PCR amplification using the BIOMED-2 primer system. Gel electrophoresis of heteroduplexes was used to analyze immunoglobulin gene rearrangements. ...

In rare instances, two distinct lymphomas concurrently occur in a patient. Such composite lymphomas can be combinations of two non-Hodgkin lymphomas or a combination of a non-Hodgkin lymphoma and a Hodgkin's lymphoma. Composite lymphomas pose a particular diagnostic challenge, and there are currently no agreed standards for treatment. Combined B-cell non-Hodgkin lymphomas are often clonally unr...

Malignant lymphomas that secondarily involve the skin are relatively common and may be difficult to distinguish from primary skin lymphomas. While the morphologic features of primary and secondary lymphomas of the skin are often very similar, the clinical behavior of primary and secondary disease is often dramatically different. Although large series of secondary cutaneous lymphomas are uncommo...

BACKGROUND Lymphomas represent the fifth most frequent cancer in Lebanon. However, little is known concerning epidemiologic characteristics and distribution of lymphoid neoplasms according to the 2008 WHO classification. MATERIALS AND METHODS We conducted a retrospective study of lymphoma cases diagnosed from 2008 till 2012 at Hotel-Dieu de France University Hospital. RESULTS A total of 502...

s European Veterinary Conference Voorjaarsdagen 2008 | 91 Dermatology Cellular phenotype The classic neoplastic cells in canine CETL are CD3+ (a common marker of all T-lymphocytes) and in 80% of the cases CD4-/CD8+ cytotoxic T cells. In 20% of the cases, CD4-/CD8lymphocytes (natural killer cells) are found. In man, 90% of CETL cases are due to clonal expansion of T-helper lymphocytes (CD4+/CD8-...

A high incidence of a T cell phenotype of sinonasal lymphomas in other Asian countries has been associated with a high incidence of Epstein Barr virus (EBV) infection. We analyzed 13 sinonasal and 18 Waldeyer's ring lymphomas for the prevalence of EBV encoded RNA (EBER) using a sensitive and specific in situ hybridization. In addition, we examined the relationship of histologic findings and imm...

BACKGROUND AND PURPOSE ADCs may help distinguish benign from malignant head and neck diseases. We sought to evaluate the effectiveness of ADC for differentiating between carcinomas and lymphomas of the nasopharynx and oropharynx. MATERIALS AND METHODS We retrospectively compared the ADCs between 24 histologically proved lymphomas and 32 carcinomas, including 8 NPCs and 7 lymphomas of the naso...
