Plain-English summary
A 3-year-old male Tosa dog was found to have a mass in his heart that was blocking blood flow. Unfortunately, when the dog passed away, a necropsy revealed multiple tumors not only in the heart but also in the lungs and liver. The tumors were linked to a rare type of cancer that had spread throughout his body. This case highlights a serious condition that can affect dogs, and it’s important for pet owners to be aware of heart-related symptoms in their pets.

Abstract
A mobile right-ventricular mass dynamically occluding the right ostium atrioventriculare in the systolic phase was detected in a 3-year-old male Tosa dog by echocardiography. At necropsy, multiple tumor masses of various sizes were observed in the heart base right ventricular lumen, myocardium, lung and liver. Dysplasia of tricuspid valve characterized by irregular shape of leaflets, upward malposition of large papillary muscles, and shortened and stout chordae tendineae was also detected. Histopathologically, the tumor cells, arranged in sheets or nests, were polyhedral with lightly eosinophilic and finely granular cytoplasm, and contained a hyperchromatic round or oval nucleus. By Grimelius' silver stain, tumor cells had cytoplasmic positive granules. Ultrastructurally, tumor cells contained characteristic small membrane-limited granules. This is the first report of metastatic intracavitary cardiac aortic body tumor in a dog.
