A 61-year-old female was found to have a nodule in the left lobe of the thyroid. FNA smears showed several clusters of atypical polygonal cells, some of which had bizarre nuclei and intranuclear inclusions. DPP IV staining was negative for these tumor cells. It was difficult to make a diagnosis of this thyroid tumor based only on the cytological findings. Histologically the tumor was encapsulated and composed of follicular and solid proliferation of atypical cells with frequent bizarre nuclei and intranuclear inclusions. These findings were compatible with those of atypical adenoma of the thyroid. Careful examination is recommended when making a cytological diagnosis of this type of tumor.
