STUDY DESIGN: Twenty-four consecutive patients (23 women and 1 man) with Hashimoto's thyroiditis combined with nodular lesions revealed by ultrasonography were included in the study. Ultrasound-guided FNAC was performed on their thyroid tissue compatible with Hashimoto's thyroiditis and nodular lesions. RESULTS: Two of 24 patients (8.3%) had papillary thyroid cancer, which was diagnosed from aspirates of 31 nodular lesions and confirmed by operative pathologic findings. CONCLUSION: If a patient with Hashimoto's thyroiditis has nodular lesions shown by ultrasonography, ultrasound-guided FNAC is helpful in elucidating the nature of the lesion and determining whether to request an operation.Aspiration biopsy; Goiter, nodular; Hashimoto's disease; Ultrasonography[SDGs]SDG3adult; aged; article; aspiration biopsy; cancer cytodiagnosis; clinical article; consensus; diagnostic accuracy; diagnostic imaging; echography; female; Hashimoto disease; histopathology; human; human tissue; image analysis; male; medical decision making; practice guideline; priority journal; thyroid nodule; thyroid papillary carcinomajournal article10.1159/0003264322-s2.0-4644304151
