Resumo
Background: Endocrine tumors are considered rare in veterinary medicine. Studies suggest that only one or two per cent of these are primary neoplasms of the adrenal glands. Concerning the histological classifi cation of these masses, the most frequently occurring malignant neoplasms in dogs are adenocarcinomas and pheochromocytomas and, among the benign tumors, adenomas are the most common. Although much rarer, hemangiomas, myelolipomas, among others, may also occur. Dogs with this kind of neoplasm could be asyntomatic or show gastrointestinal signs, pain and urinary tract infection. Adrenalectomy is the treatment of choice and could be curative in most cases. This paper reports a case of two concurrent benign, rare adrenal neoplasms in a dog, emphasizing the clinical signs, diagnosis and treatmentCase: An eight-year-old, male castrated Chow-chow, weighting twenty one kilograms, was admitted at the Veterinary Teaching Hospital of the Federal University of Rio Grande do Sul (UFRGS) with a history of intermittent vomiting and diarrhea since it was a puppy. Because of the chronicity and nonspecifi c signs, additional tests were requested. Abdominal ultrasonography showed a round mass, measuring approximately 3.7 cm x 3.2 cm, suggesting a neoplasm. Blood pressure was measured and the mean value was 152 mmHg. Laboratory tests included a complete blood count, albumin (31.62 g/L), alaBackground: Endocrine tumors are considered rare in veterinary medicine.
