Plain-English summary
A 9-year-old male Rottweiler was brought in with a swollen belly, trouble breathing, and noticeable bulging in the rear area. Sadly, after the dog passed away, a necropsy revealed a large tumor in the heart that had spread to the lungs and caused fluid buildup around the heart. The tumor was a type of cancer called malignant mesenchymoma, which had different cell types involved. This case is particularly unusual because it's the first time this type of cancer has been reported in this location in dogs.

Abstract
A 9-year-old male rottweiler was presented with abdominal distension, ascites and respiratory distress and marked bulging in the perineal region. At necropsy examination the animal had profuse ascites and hydropericardium and a multinodular mass in the right auricle of the heart infiltrating the epicardium and pericardium and metastasizing to the caudal lobe of the left lung. Microscopically and immunohistochemically the tumour was composed of neoplastic cells with muscular, cartilaginous and adipose differentiation. A diagnosis of malignant mesenchymoma with leiomyosarcomatous (≈ 50%), rhabdomyosarcomatous (≈ 30%), chondrosarcomatous (25%) and liposarcomatous (5%) components was made. Metastatic malignant mesenchymoma has not been reported previously at this site in the dog.
