Fine Needle Aspiration Cytology of the Thyroid Gland Following Methimazole Therapy - Abstract
Carbimazole is widely used for treatment in patients with hyperthyroidism. Cytopathological and histopatholgical changes in patients with toxic goiter, following carbimazole therapy have been rarely documented. In this article, I report a case of 46-year-old female patient who clinically presented with features of hyperthyroidism.
Fine needle aspiration biopsy was performed on her thyroid gland. The absence of drug treatment history caused serious misinterpretation. She was referred to a surgeon, and total thyroidectomy was performed. After diligent search, no malignancy was found. However, on discussion with surgeon; it was found that the patient was on methimazole. Therefore, a final diagnosis of methimazole-induced changes was rendered.
