COMPACT CANINE THYROID CARCINOMA: A CASE REPORT IN A SRD DOG FROM ANÁPOLIS-GO

Abstract

This study describes a clinical case of compact thyroid carcinoma in an elderly mixed-breed female dog, attended in Anápolis, Goiás, Brazil. The diagnosis was established through histopathological analysis, which revealed a malignant neoplasm with aggressive behavior and invasive potential. Literature review showed that thyroid carcinomas in dogs are relatively uncommon but present high clinical relevance due to their reserved prognosis and the demand for specific therapeutic approaches. The main treatment modalities were discussed, including surgery, radioiodine therapy, and targeted therapies such as toceranib, which have demonstrated clinical benefits in advanced cases. It is concluded that a multidisciplinary approach, early diagnosis, and appropriate therapeutic choice are essential to prolong survival and improve patients’ quality of life. This report contributes to the regional scientific record and to the advancement of knowledge in veterinary oncology.
