Adequate sampling of multiple thyroid nodules by fine-needle aspiration.

Biopsy of 3 different nodules in patients with multiple nodules appears to lower the risk of malignancy to that of a benign fine-needle aspiration specimen. Although exceptions can occur, cytologists may be able to improve the accuracy of their diagnoses by focusing predominantly on identifying papillary carcinoma after the first 2 nodules have been biopsied.
