Abstract

Compared to the other chemodectoma, aortic body tumors, the carotid body tumor is rarer and more often malignant. In the present case, a 12-year-old, intact female Shih-tzu dog presented to the hospital with a right ventral cervical mass. The mass was diagnosed by immunohistochemical staining with chromogranin A (CgA) as a carotid body tumor. The cervical mass and metastasized lymph node were removed by surgical resection. Because the dog had valvular heart disease, chemotherapy with carboplatin was initiated over 6 months to prevent metastasis and recurrence as an adjunctive treatment. After over two years of management, tumor metastasis and recurrence were not observed until recently. This report shows that proper management and chemotherapy as an adjunctive therapy can treat carotid body tumors in elderly dogs with concurrent heart disease.
