BACKGROUND Splenic marginal zone lymphomas (MZL) in dogs arise from the marginal zone of B-cell follicles and can progress slowly. OBJECTIVES To describe clinical features, treatment, and outcome of dogs with splenic MZL. ANIMALS Five dogs with naturally occurring MZL. METHODS Clinical, laboratory, and follow-up data were retrospectively reviewed.(More)
Cytosine arabinoside (ara-C) is a component of many protocols for the treatment of acute leukaemia and non-Hodgkin lymphomas in humans. The aim of the study was to prospectively evaluate the efficacy of ara-C in a myeloablative regimen in a cohort of canine lymphomas with bone marrow involvement. Seventeen dogs were enrolled. Eight were treated with a(More)
OBJECTIVE To describe clinical characteristics, treatment, and outcome of dogs with inflammatory carcinoma (IC) and identify patient-, tumor-, and treatment-related factors associated with overall survival time. DESIGN Retrospective case series. ANIMALS 43 client-owned dogs. PROCEDURES Records of dogs with a clinical diagnosis of IC that had(More)
OBJECTIVE To determine factors predicting survival in dogs with high-grade multicentric lymphoma. Design-Retrospective cohort study. Animals-127 dogs with high-grade multicentric lymphoma evaluated at 4 veterinary hospitals from 2000 to 2009. PROCEDURES Records were reviewed to identify dogs with completely staged high-grade multicentric lymphoma treated(More)
Vascular endothelial growth factor (VEGF) and metalloproteinase (MMP) 2 and 9 are useful biomarkers in human lymphoma. During cancerogenesis, transforming growth factor beta (TGF-β) stimulates VEGF and MMPs production. VEGF and TGF-β plasma levels were tested by ELISA, MMP-2 and MMP-9 by gelatine zymography in 37 dogs with lymphoma, 13 of which were also(More)
Perivascular wall tumors (PWTs) are defined as neoplasms deriving from mural cells of blood vessels, excluding the endothelial lining. The spectrum of human cutaneous PWT includes glomus tumor, hemangiopericytoma (HEP), myopericytoma, angioleiomyoma/sarcoma, angiomyofibroblastoma, and angiofibroma. The purpose of this study was to revise clinical(More)
BACKGROUND Chronic lymphocytic leukemia (CLL) is a hematologic disorder in dogs, but studies on prognostic factors and clinical outcome are lacking. In people, several prognostic factors have been identified and currently are used to manage patients and determine therapy. OBJECTIVES The aim of the study was to determine if the immunophenotype of(More)
The role of oestrogens and their receptors (ERs) in prostatic growth and differentiation and in the progression of prostatic carcinoma has been well investigated in human medicine. In dogs, however, available reports on the expression of ERs in normal, hyperplastic or neoplastic prostates are few and controversial, or completely lacking. Three normal, three(More)
Richter's syndrome (RS) is the development of an aggressive lymphoma in patients with chronic lymphocytic leukaemia (CLL). In humans, RS occurs in 2-20% of CLL, which transform into diffuse large B-cell lymphoma but reports in dogs are scarce. This study retrospectively describes eight dogs with CLL progressing into RS. A database including 153 dogs with(More)
Three dogs diagnosed with aspergillosis developed sinonasal tumors several months after successful treatment with topical clotrimazole solution. Chronic rhinosinusitis was also detected in all cases prior to diagnosis of sinonasal tumors. The inflammatory response to Aspergillus, clotrimazole treatment, and chronic inflammation after treatment are discussed(More)
