Symptomatic Hyperthiroidism associated with Carcinoma in a Dog

Abstract

The dog came to the clinic because of anxiety, restlessness and dysorexia for several months at the beginning of the summer and persisting throughout the day, with progressive worsening. Based on all the investigations performed, in order to obtain a diagnosis of certainty, we first proceeded with cytopathological examination of the thyroid lesion, the result of which primarily defined the presence of a thyroid carcinoma. Second, the cytopathology of the peritoneal nodules suggests mesothelial reactivity. It was decided to proceed surgically with right thyroidectomy. The dog experienced an unexpected long remission and to date, five years after recovery, the patient has not presented any organic or behavioural problems.
