Background: Lipogranulomatous lymphangitis is inflammation of the intestinal lymphatic vessels and surrounding tissues caused by chronic leakage of lipid-laden chyle. Grossly, lipogranulomas are typically disseminated small masses on the serosa and surrounding lymphatic vessels and consist of...

Proliferative disorders of lymphatic origin in animals are mostly congenital or occur within the first few months of life. Involvement of internal organs is extremely infrequent. A seven-year-old entire female mixed-breed dog was presented with apathy and poor appetite. Abdominal ultrasonography...

Abdominal ultrasonographical and computed tomography examinations of a 12-year-old neutered female toy poodle revealed a protruding mass, approximately 2 cm in diameter, at the apex of the bladder. The mass was firm and haemorrhagic with a homogeneously brownish-yellow cut surface. Microscopically, ...

The aim of this paper is to describe the clinical and pathological findings in a case of intestinal lymphangiectasia associated with lipogranulomatous lymphangitis in a 14-months-old male Pit Bull dog presented at the Hospital de Clínicas Veterinárias on Universidade Federal do Rio Grande do Sul,...

Recurrent and chronic digestive disorders are a regular clinical presentation in small animal practice. Several complementary exams are available in veterinary medicine to help reduce the differential diagnosis such as blood analysis, medical imaging, endoscopy and surgery. When such digestive...

Canine mammary tumours (CMTs) are the most common tumours of entire female dogs and represent a promising model for human breast cancer. Little is known about the presence and prognostic value of lymphangiogenesis in CMTs. The aims of the present study were to analyze selected characteristics of ...

Lymphangiosarcomas are uncommon vascular neoplasms that arise from lymphatic endothelial cells (LECs). They efface and replace normal subcutaneous tissue and are characterised by arborising, vascular channels lined by a single layer of pleomorphic endothelial cells and a paucity of erythrocytes....

Background: Intestinal lymphangiectasia (IL), a type of protein-losing enteropathy (PLE), is a dilatation of lymphatic vessels within the gastrointestinal tract. Dietary fat restriction previously has been proposed as an effective treatment for dogs with PLE, but limited objective clinical data are ...

Intestinal lymphatic hypoplasia (ILH) is a rare but well-documented cause of protein-losing enteropathy (PLE) in human infants. To our knowledge, this condition has not been reported previously in veterinary medicine. Here we report the clinical and histopathological findings in three dogs that...

Canine mammary tumours (CMTs) are the most common neoplasms in intact female dogs. Bitches with spontaneously arising CMTs represent a promising animal model for human breast cancer research. The aim of the present study was to develop an immunohistochemical protocol for the identification of blood ...
