Subcutaneous rhabdomyosarcoma in an old rabbit.

An 11-year-old castrated male rabbit presented with a subcutaneous mass in the right hind limb. The mass comprised solid and myxoid areas. Solid areas were characterized by a storiform or interlacing pattern of spindle cells, strap cells, multinucleated giant cells and round cells with eccentrically located nuclei, whereas the myxoid areas were composed predominantly of elongated fusiform cells with hyperchromatic nuclei embedded in Alcian Blue-positive myxoid stroma.

Spindle cell ameloblastic carcinoma in a labrador retriever dog.

A 13-year-old castrated male Labrador retriever dog presented with a mass caudal to the first molar of his left mandible. Although the tumor was excised, a recurrent tumor was detected one month later and resected. Both tumors displayed invasive growth and were composed of neoplastic proliferation arranged in irregular lobules, nests and cords continuous with mucosal epithelium.

Administration of angiotensin receptor II blockade improves vascular function, urinary albumin excretion, and left ventricular hypertrophy in low-risk essential hypertensive patients receiving antihypertensive treatment with calcium channel blockers.

We examined calcium channel blockers (CCBs) and angiotensin receptor II blockers in low-risk hypertensives to evaluate renal, vascular function and left ventricular mass (LVM) from the viewpoint of salt intake (SI). Low-risk hypertensives who had not met blood pressure (BP) goals with CCB were administered telmisaltan. Office and home BP, urinary albumin excretion (uAE), brachial ankle pulse wave velocity (baPWV) and LVM were significantly reduced.

Gastric pleomorphic leiomyosarcoma in a Shetland sheepdog.

A solitary mass of 6 x 6 x 5 cm was found in the smooth muscle layer of the pyloric part in the stomach of a Shetland sheepdog. The excised mass was solid, gray-white in color, and had central necrosis with hemorrhages. Microscopically, the neoplasm was composed of irregular bundles of spindle-shaped tumor cells and round tumor cells.
