PURPOSE: Hand- and robot-guided mini gamma cameras have been introduced for the acquisition of single-photon emission computed tomography (SPECT) images. Less cumbersome than whole-body scanners, they allow for a fast acquisition of the radioactivity distribution, for example, to differentiate cancerous from hormonally hyperactive lesions inside the thyroid. This work compares acquisition protocols and reconstruction algorithms in an attempt to identify the most suitable approach for fast acquisition and efficient image reconstruction, suitable for localization of extended sources, such as lesions inside the thyroid...

BACKGROUND: Carcinomas of the thyroid follicular epithelium are the most common cancers of the endocrine system. In the diagnosis of thyroid nodules and tumors, the gold standard is histological evaluation. In cases which have morphological overlap, immunohistochemistry is needed for differential diagnosis. The purpose of this study is to investigate the expressions of CD56, HBME-1, cytokeratin 19 (CK19) antibodies in papillary thyroid carcinoma (PTC) and thyroid nodular lesions and their contributions to differential diagnosis...

The risk of cancer is relatively higher in Graves' patients presenting simultaneously with thyroid nodules. Radioiodine (RAI) therapy recommended in high-risk differentiated thyroid carcinoma may be associated with worsening of a pre-existing Graves' orbitopathy (GO) or developing a new onset. The impact of RAI therapy in patients with differentiated thyroid cancer on the course of a pre-exisiting GO has not been specifically investigated.The aim of this study is to assess the influence of RAI treatment administered for differentiated thyroid cancer on the course of a pre-existing GO...

BACKGROUND: Molecular testing provides an important ancillary study for thyroid nodules with indeterminate cytology. The nomenclature shift to "noninvasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP) will impact the performance of molecular tests. For the current study, the authors reviewed the performance of the Afirma gene-expression classifier (GEC) and the University of Pittsburgh Medical Center (UPMC) targeted mutation panel tests in thyroid nodules that were subsequently diagnosed as NIFTP on surgical resection...

BACKGROUND Clinical cases of nonmedullary thyroid carcinoma (NMTC) in combination with primary hyperparathyroidism (PHPT) have been reported occasionally. However, the clinical characteristics and risk factors of concomitant NMTC in PHPT patients remain unclear. This study aimed to assess the association between PHPT and NMTC, and evaluate the clinical characteristics and risk factors of NMTC in Chinese patients with PHPT. MATERIAL AND METHODS This was a retrospective cohort analysis. We reviewed the medical records of 155 patients who underwent surgery for PHPT in two large medical centers in China between 2009 and 2014...

BACKGROUND: Preoperative detection of RAS mutations can contribute to cancer risk assessment in indeterminate thyroid nodules, although RAS is not always associated with malignancy. METHODS: Fine-needle aspiration samples classified in 1 of 3 indeterminate cytology categories were prospectively tested for N-, H-, and K-RAS mutations using next-generation sequencing assay. RESULTS: In the study, 93 patients with 94 nodules had preoperative RAS detected, of whom 86 patients had an operation (69% total thyroidectomy, 29% lobectomy)...

Shear wave elastography (SWE) is a new non-invasive diagnostic imaging technique, that maps the elastic properties of tissues. Nowadays this modality develops increasingly in medicine across its disciplines and opens a new era of high-quality ultrasound examination because it increases the specificity and thus improves diagnostic assurance. This method is similar to manual palpation, shows elastic properties of biological tissues and provides a kind of reconstruction of the internal structure of soft tissues based on measurement of the response of tissue compression...

BACKGROUND: Molecular analysis for common somatic mutations in thyroid cancer can improve diagnostic accuracy of fine-needle aspiration cytology (FNAC) in the nondiagnostic or indeterminate category of thyroid nodules. In this study, we evaluated the feasibility of molecular diagnosis from residual liquid-based cytology (LBC) material after cytological diagnosis. METHODS: This prospective study enrolled 53 patients with thyroid nodules diagnosed as nondiagnostic, atypia of undetermined significance (AUS), or follicular lesion of undetermined significance (FLUS) after FNAC...

Primary squamous cell carcinoma of the thyroid is a very rare thyroid malignancy (less than 1% of thyroid cancers) with unfavorable clinical evolution and median survival less than one year, due to highly local tumor invasiveness with airway obstruction, metastases and treatment complications. We present a 62-year-old female patient with a fixed, rapidly increasing 5 cm right thyroid nodule, generating compressive signs and significant weight loss, resembling anaplastic thyroid carcinoma. Thyroid hormones, antithyroid antibodies and calcitonin were normal...

Thyroid cancer is the most frequent endocrine neoplasia. The incidence of the disease has been increasing in the past few decades in many regions, especially where the population was subject to some forms of accidental exposure. Among all the histopathological forms, papillary thyroid cancer (PTC) is the most common histological subtype of malignant thyroid tumor, representing about 80-90% of all malignant thyroid tumors. Although it is generally accepted that tumor stroma plays an essential role in the development and metastasis of tumor cells, histopathological studies focused on tumor cells characteristics...

Epithelial thyroid cancers (TC) comprise two differentiated histotypes (DTC), the papillary (PTC) and the follicular (FTC) thyroid carcinomas which, following dedifferentiation, are assumed to give rise to the poorly differentiated thyroid carcinomas and the rare, but highly aggressive and invariably fatal, anaplastic thyroid carcinomas. Although thyroid cancer mortality has not been changed, its annual incidence has increased over the last two decades, mainly because of the improved ability to diagnose malignant transformation in small non-palpable thyroid nodules...

We report a case of incidental uptake of 99mTc-methylene diphosphonate in the thyroid in a 62-year-old female with a history of breast cancer treated with quadrantectomy, chemotherapy and radiotherapy, who underwent total-body-bone scintigraphy during follow up. Planar scintigraphy was followed by neck SPECT-CT that demonstrated an area of increased tracer uptake in the neck at the left lobe of the thyroid. Neck ultrasonography showed a nodule corresponding to SPECT-CT finding and the ultrasound-guided fine needle aspiration documented the presence of papillary carcinoma...

The antibiotic minocycline is virtually pathognomonic for brown-black discoloration of the thyroid gland referred to as 'black thyroid'. Black thyroid' is an incidental finding in patients taking the drug who undergo thyroid surgery for another indication and is not of known clinical significance. However, its recognition is important so as not to raise concern for a disease process. Here, we present the first case of 'black thyroid' attributable to the iodine-containing compound indocyanine green. Intraoperative indocyanine green was administered as part of a research protocol transoral robotic-assisted surgery for a base of tongue cancer in a 44-year-old man...

BACKGROUND: Clinicians are confronted with an increasing number of patients with thyroid nodules. Reliable preoperative diagnosis of thyroid nodules remains a challenge because of inconclusive cytological examination of fine-needle aspiration biopsies. Although molecular analysis of thyroid tissue has shown promise as a diagnostic tool in recent years, it has not been successfully applied in routine clinical use, particularly in Chinese patients. METHODS: Whole-transcriptome sequencing of 19 primary papillary thyroid cancer (PTC) samples and matched adjacent normal thyroid tissue (NT) samples were performed...

BACKGROUND: The purpose of this study was to investigate the impact of lymphocytic thyroiditis on incidence of incidental thyroid cancers. METHODS: We conducted a retrospective review of 713 consecutive patients who underwent thyroidectomies. Incidental thyroid cancer was defined as an unexpected cancer discovered on pathological examination outside the index nodule undergoing preoperative cytology. RESULTS: We excluded 65 cases because of preoperative diagnosis of thyroid cancer, and 68 because of nonincidental cancer within the index nodule...

BACKGROUND: Thyroid nodules are a common presenting complaint for endocrine surgeons; many require ultrasound-guided fine-needle aspiration cytology (US-FNAC). In an attempt to streamline our service, we introduced same-day surgeon-performed US-FNAC in 2014. METHODS: Three groups were defined: (A) retrospective group with FNAC performed in radiology prior to August 2014; (B) prospective radiology FNAC group; and (C) prospective surgeon-performed group. Demographics, nodule characteristics, pathology and management plans were recorded...

About one third of focal thyroid uptakes in a fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) study are malignant, the most frequent histological type being papillary carcinoma. Metastases to the thyroid account for approximately 7.5% of thyroid malignancies and come mainly from kidney, lung, head and neck, and breast cancers. We report the case of a 64-year-old woman presenting a fast growing thyroid nodule whose primitive or metastatic origin was not obvious, for which (18)F-FDG PET/CT helped in the diagnostic process and in the later management of the patient...
