Discussion: Misdiagnosis analysis and prevention strategies: The calcification of PTC concomitant with HT is common and diverse, calcification occurs in the background of HT, whether microcalcification, coarse calcification, or isolated calcification suggests a malignant risk, so careful observation of calcification is helpful to improve the diagnostic rate of PTC in HT background. Ohmori et al. found that dense calcification foci were more often occurred in the papillary thyroid cancer patients concomitant with HT, while psammoma bodies were rare. Therefore, attention should be paid to calcification observed in the HT background nodules.
