Abstract
Kaposiform hemangioendothelioma is a rare vascular tumor that almost exclusively occurs in children. It is a low-grade malignant neoplasm that is locally aggressive but without proven metastatic potential. Herein, we describe a case of Kaposiform hemangioendothelioma in a 10-year-old male dog. To the best of our knowledge, this is the first report of this vascular tumor occurring in a nonhuman animal species. The tumor was located on the ventromedial surface of the posterior limb. Microscopic examination of the lesion revealed a multinodular tumor with sheets of spindled endothelial cells forming vascular slits similar to Kaposi's sarcoma and peripheral tumor lobules resembling capillary hemangioma.

Abstract
The mechanism of tumor cell killing by OXI4503 was investigated by studying vascular functional and morphological changes post drug administration. SCID mice bearing MHEC5-T hemangioendothelioma were given a single dose of OXI4503 at 100 mg/kg. Tumor blood flow, measured by microsphere fluorescence, was reduced by 50% at 1 hr, and reached a maximum level 6-24 hr post drug treatment. Tumor vascular permeability, measured by Evan's blue and hemoglobin, increased significantly from 3 hr and peaked at 18 hr. The elevated tumor vessel permeability was accompanied by an increase in vascular endothelial growth factor (VEGF) from 1 hr post drug treatment. Immunohistochemical staining for CD31 and laminin showed that tumor blood vessels were affected as early as 3 hr but more prominent from 6 hr. From 12 hr, the vessel structure was completely destroyed. Histopathological and double immunohistochemical staining showed morphological change and induction of apoptosis in endothelial cells at 1-3 hr, followed by tumor cell necrosis from 6-72 hr. There were no statistically significant changes of Evan's blue and hemoglobin contents in liver tissue over the time course. These results suggest that OXI4503 selectively targets tumor blood vessels, and induces blood flow shutdown while it enhances tumor blood vessel permeability. The early induction of endothelial cell apoptosis leads to functional changes of tumor blood vessels and finally to the collapse of tumor vasculature, resulting in massive tumor cell necrosis. The time course of the tumor vascular response observed with OXI4503 treatment supports this drug for development as a stand alone therapy, and also lends support for the use of the drug in combination with other cancer therapies.

Abstract
An unusually high, unprecedented prevalence of cardiac hemangioendotheliomata, including hemangiomas, hemangioendotheliomas, and hemangioendotheliosarcomas, was found in a laboratory cohort of the small, teleost fish Rivulus marmoratus. The neoplasms occurred in 51 of 204 fish (25%) used in a carcinogenicity study of butylated hydroxyanisole fed in a lyophilized chicken liver diet for up to 9 months. The cardiac neoplasms occurred in approximately equal numbers of both control (fed lyophilized chicken liver but not exposed to butylated hydroxyanisole) and exposed (fed 0.8% butylated hydroxyanisole in chicken liver) fish. The neoplasms occurred in the bulbus arteriosus and ventricle (accompanied by an intense epicarditis), and in some cases, in the gills. At least one case of hemangioma was characterized by cavernous vessels in the bulbar wall. Hemangioendothelioma cases consisted of pleomorphic endothelial cells that formed continuous tracts and anastomosing, typical vascular channels of varying sizes. The hemangioendotheliosarcomas consisted of atypical, spindle, polygonal, or round endothelial cells that formed solid tumor masses that contained abnormal vessels with atypical endothelium tufting into their lumina. Some fish had neoplasm cases containing varying regions with mixtures of the above features. Incipient neoplasms occurred on/in the semilunar valves, and their cells appeared to invade the adjacent walls of the bulbus and/or the ventricle. The gill lesions represented possible metastatic neoplasms, probably formed by atypical endothelial cells that exfoliated from the edges of cardiac neoplasms into the lumina of the ventricle or bulbus and were then pumped to the arterioles of the gills via the ventral aorta. Fish examined from the original colony in the laboratory and from the wild had no neoplasms. Possible causes are discussed, and studies are under way in an attempt to determine the etiology of the neoplasm and to evaluate Rivulus marmoratus as a possible model organism for study of these types of cardiac neoplasms.

Abstract
Four solid tumours (one haemangiopericytoma, one haemangioendothelioma, one spindle-cell sarcoma and one mammary carcinoma) in dogs were analysed cytogenetically. In the haemangiopericytoma, an additional small chromosomal segment was present. Very complex changes including centric fusions and symmetric meta-centrics 1, 6, 10 and 12 were conspicuous in the highly unbalanced karyotype of the haemangioendothelioma. Complex changes, particularly many centric fusions and a tandem translocation 4/14, were features of the spindle-cell sarcoma. One centric fusion and a symmetric metacentric 13 were present in the mammary carcinoma.

Abstract
The microscopical, ultrastructural and immunohistochemical features of an unusual type of haemangioendothelioma in the brain of a calf are described. The salient features of this tumour were an exuberant proliferation of vasoformative elements whose endothelial cells exhibited epithelioid and spindle cell features. Intracytoplasmic miniature lumen formation in endothelial cells was characteristic of this vascular neoplasm.

Abstract
An 8-year-old German Shepherd bitch developed a haemangioendothelioma in the mammary region. The cytogenetic characterization of the tumour cells revealed a chromosome number of 80 plus a double minute. Several aberrations were detected: trisomies 4, 35, and 38, a centric fusion 8/22 and a tandem translocation 9/23.

Abstract
Neoplastic angioendotheliomatosis was diagnosed in a nine-year-old, intact male German Shorthaired Pointer exhibiting progressive neurological signs over a six-month period. At necropsy, there was multifocal asymmetric, hemorrhagic necrosis within the cerebral hemispheres, centrum semiovale, caudate nucleus, and internal capsule. Histologically, there was extensive intravascular proliferation of pleomorphic mononuclear cells within the brain and multiple parenchymatous organs. Transmission electron microscopy demonstrated the absence of intercellular junctions between neoplastic cells. These cells were not attached to the vascular lining endothelium; Weibel-Palade bodies and a basement membrane were lacking. By indirect immunofluorescence, positive cytoplasmic staining of intravascular neoplastic cells for IgG was demonstrated. Peroxidase-antiperoxidase technique for Factor VIII related antigen was negative. As in man, this rare neoplastic disorder appears to be a lymphoma, apparently of the B cell line.

Abstract
A 6-year-old dog which presented with weakness of the hind limbs progressed to a cerebral disorder with altered sensorium. The cerebrospinal fluid (CSF) protein was elevated, but no cells were found. Autopsy revealed severe hemorrhages in the basal nuclei and diencephalon. Histology of the lesions showed many meningeal and parenchymal blood vessels filled with neoplastic mononuclear cells. Electron microscopy of the tumor cells demonstrated ribosomes, granular endoplasmic reticulum, mitochondria, and a few lysosomes. Immunocytochemical procedures to demonstrate Factor VIII-related antigen were negative. This appears to be the first recorded case of cerebral angioendotheliomatosis in domestic animals and closely resembles the syndrome in man.

Abstract
The nude mouse was used to evaluate transplantation of feline tumors and subsequent doxorubicin chemotherapy. Three mammary gland adenocarcinomas and one salivary gland adnoecarcinoma were readily transplanted. All were successfully passed at least once. The two sarcomas, a fibrosarcoma and a malignant hemangioendothelioma, failed to grow when transplanted. Growth rates for the adenocarcinomas appeared to be specific for individual tumors. Generally, tumor weights increased five to eight times by days 40 to 50. Structural changes were not observed histopathologically in tumors transplanted several times. When doxorubicin was given intraperitoneally (1 mg/kg of body weight) weekly for 6 weeks to nude mice with transplanted feline mammary gland adenocarcinoma, there was no significant difference (P less than 0.05) in weights of tumors of experimental (n = 150 and control (n = 10) mice.
