Background. Popularization of cervical ultrasound led to higher detection of papillary thyroid carcinoma (PTC) and primary hyperparathyroidism (PHPT), as well as increasing percentage of asymptomatic PHPT in China. Although the coexistence of PTC and PHPT has been reported, it is unknown whether the clinicopathological features of PTC differ between asymptomatic and symptomatic PHPT patients. Methods. We retrospectively reviewed the medical records of 304 PHPT patients treated in our hospital between January 2009 and July 2020, including 217 females and 87 males with the average age of 53.27 ± 13.54 years. Of the 304 patients, 181 were symptomatic PHPT patients and 123 were asymptomatic PHPT patients. We analyzed the laboratory results, postoperative pathology, and the TNM stage of PTC between asymptomatic and symptomatic PHPT patients. Results. Concurrent thyroid nodules were found in 61.51% of PHPT patients, and the prevalence of PTC in thyroidectomized PHPT patients was 29.89% in our cohort. Lower serum parathyroid hormone (PTH) ( p < 0.05 ) and calcium ( p < 0.05 ) were found in PHPT patients with PTC compared to patients with benign thyroid lesion. Compared with the symptomatic PHPT patients, the asymptomatic PHPT patients showed lower serum calcium ( p < 0.05 ), serum chlorine ( p < 0.05 ), alkaline phosphatase ( p < 0.05 ), PTH ( p < 0.05 ), and bone turnover markers ( p < 0.05 ) but higher prevalence of thyroid nodules (70.73% versus 55.24%, p < 0.05 ) and PTC (15.44% versus 3.87%, p < 0.05 ). All the PTC in symptomatic PHPT patients were papillary microcarcinoma limited to the thyroid, while 68.42% and 15.78% of the PTC in asymptomatic PHPT patients showed microscopic extrathyroidal extension and lymph node metastases, respectively. Moreover, 36.84% (7/19) of the PTC patients in asymptomatic group showed multifocality, which was much higher than 14.29% (1/7) in the symptomatic group; however, no statistical significance was found ( p = 0.24 ). Conclusions. The concomitant PTC in asymptomatic PHPT patients showed a higher rate of microscopic extrathyroidal invasion when compared to symptomatic PHPT patients. So the FNA is essential to the asymptomatic PHPT patients with suspicious thyroid nodules and once the PTC is confirmed, concurrent parathyroidectomy should be performed with thyroidectomy in asymptomatic PHPT patients.

Abstract Context: PET CT imaging methods based on fibroblast activation protein inhibitors (FAPIs) have recently demonstrated promising clinical results. Objective: We aimed to evaluate the use of 68Ga-FAPI PET / CT and 18FDG PET / CT imaging techniques to detect the metastatic foci in recurrent papillary thyroid carcinoma.Design and Patients: This is a prospective study. Patients who were diagnosed with papillary thyroid carcinoma, achieved biochemical recovery after the first operation and having recurrence for papillary thyroid carcinoma on the follow up were included in the study. [68Ga] Ga-DOTA-FAPI-04 and [18F] FDG PET / CT were performed for comparative purpose and detection of recurrence localization.Results: [18F] FDG PET / CT detected the metastatic foci in 21 of 29 patients (72.4%), [68Ga] Ga-DOTA-FAPI-04 was able to detect the metastatic foci in 25 of 29 patients (86.2%). When the two imaging techniques were used together, the metastatic foci in 27 of the 29 patients could be detected (93.1%.). Also between the [18F] FDG PET / CT SUVmax values and [68Ga] Ga-DOTA-FAPI-04 SUVmax values, a statistical significance was found in favor of 68Ga-FAPI PET (p = 0,002).Conclusion: In conclusion, 68Ga-FAPI PET imaging technique can be used as an alternative method to detect the metastatic focus or foci in patients with recurrent papillary thyroid carcinoma. It can also increase the chance of metastatic focus or foci detection when used in conjunction with the 18 FDG PET.

Objective: Here we present 2 cases of papillary thyroid microcarcinomas (PMCs) that had metastasized at presentation. The 2015 American Thyroid Association and the American College of Radiology Thyroid Imaging Reporting and Data System (TI-RADS) criteria do not recommend biopsy of the majority of subcentimeter thyroid nodules, as PMCs are mostly indolent with excellent prognosis. However, the paradigm of active surveillance presents a conundrum on how to identify the rare patient with distant metastatic disease while avoiding unnecessary intervention in the majority. Methods: After initial discovery of incidental lesions on chest computed tomography, core or wedge biopsies of the lung lesion were performed. Thyroid nodules on ultrasound were classified by TI-RADS. Tumor DNA was sequenced, annotated, filtered on 119 known cancer genes, and filtered for variants with an exome allele frequency of <0.001. Results: A 70-year-old woman and a 29-year-old woman presented with incidental pulmonary lesions on computed tomography scan. Lung biopsy revealed lung metastases from papillary thyroid carcinoma. The thyroid nodules in both patients were TI-RADS 3 and American Thyroid Association low-suspicion. Molecular testing showed a c.1721C>G mutation (p.Thr574Ser) in the TSHR gene in patient 1 and a codon 61 mutation in the NRAS gene in patient 2. Both patients were iodine-avid, with complete structural remission in one patient and ongoing treatment with evidence of structural response in the other. Conclusion: The 2 presentations demonstrate unexpected and concerning behavior of PMCs. Both thyroid tumors were subcentimeter in diameter, meaning they would have escaped detection using traditional risk-stratification algorithms in active surveillance. Further knowledge of tumor genetics and microenvironment may assist in predicting tumor behavior in PMCs.

Abstract Introduction Hashimoto thyroiditis (HT) shares many characteristics with papillary thyroid carcinoma (PTC), and some studies show that, when associated, PTC is diagnosed mostly with smaller lesions and multifocal pattern. Objective To evaluate the relationship between HT and PTC. Methods A retrospective study of 155 patients who underwent total thyroidectomy from 2009 to 2015. Demographical, clinical and ultrasonographical data, as well as anatomopathological findings were evaluated. Results There were signs of thyroidits in 35 patients, and 114 patients had a unifocal disease. There was no statistical significance between the variables studied and thyroiditis. However, when compared with the occurrence of unifocal or multifocal lesions, there was statistical significance regarding age (p = 0.038) and mass (p = 0.031). There was no direct relationship between thyroiditis and multifocality (p = 0.325) nor between thyroiditis and cervical extension of the disease (p = 0.300 e p = 0.434). Conclusion There was no relationship between thyroiditis and multifocality in cases of PTC.

History Of

Thyroid nodules are palpable on up to 7% of asymptomatic patients. Cancer is present in 8% to 16% of those patients with previously identified thyroid nodules. Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, accounting for approximately 85% of thyroid cancers. Although most appear as solid nodules on ultrasound imaging, a subset of 2.5% to 6% has cystic components. The presence of cystic changes within thyroid nodules decreases the accuracy of fine needle aspiration (FNA) in the diagnosis of thyroid cancer, given the difficulty of obtaining appropriate cellular content. This becomes a diagnostic and therapeutic challenge. We present a case of a 31-year-old female with a 1-month history of palpitations, fatigue, and night sweats, who underwent evaluation, and was diagnosed with subclinical hyperthyroidism. She presented 4 years later with compressive symptoms leading to repeat FNA, showing Bethesda III-atypia of undetermined significance and negative molecular testing. Thyroid lobectomy revealed PTC with cystic changes. This case is a reminder that patients with hyperfunctioning thyroid nodule should have closer follow-up. It poses the diagnostic dilemma of how much is good enough in the evaluation and management of a thyroid nodule. Early detection and action should be the standard of care.

The diffuse follicular variant of papillary thyroid carcinoma (DFV-PTC) is a rare malignant thyroid condition. It represents an uncommon variant of papillary carcinoma characterized by a diffuse involvement of thyroid parenchyma, follicular architecture and nuclear features of PTC in absence of a surrounding capsule. Up to date few data have been collected about this entity and, at the best of our knowledge, only 24 cases have been reported in the literature. According to these reports DFV-PTC seems to occur preferentially in young women and shows more aggressive behavior than other papillary thyroid tumors. Herein we present an unusual case of DFV-PTC occurring in an 83 years old woman, involving the entire thyroid gland, without distinct or prevalent thyroid nodules. The tumor was clinically misdiagnosed as obstructive goiter.
