While the etiology is unclear, it is known that older animals are most commonly affected, and it is commoner in dogs than in other domestic species. Clinical signs are nonspecifi c and vary according to the location of the tumor. The prognosis ranges from guarded to poor, owing to the high rate of metastasis, tissue invasion, and biochemical changes during the clinical course. Herein, we describe a case of unilateral renal capsule HSA in a 6-year-old American Pit Bull Terrier bitch. Case: A 6-year-old American Pit Bull Terrier bitch came to veterinary care with a history of recent abdominal distention and progressive weight loss. On physical examination the animal was apathetic with abdominal distention, pale mucous membranes, and a body temperature of 37.5C. Abdominal ultrasonography revealed fl uid collection in the peritoneal cavity. The origin of the fl uid could not be determined because of the extent of the fluid collection, which occupied the abdominal cavity throughout its length. In preoperative hematologic tests, anemia, lymphopenia, monocytosis, and hyperproteinemia were observed. At exploratory laparotomy, a large mass was found in the abdominal cavity, attached to the left renal parenchyma and containing bloody fluid. Owing to its poor state of health, the patient died...(AU)
