OBJECTIVE: The purpose of this study was to evaluate thyroid nodule margins for specific morphologic features and determine the diagnostic performance of these features in differentiating papillary carcinoma from benign thyroid nodules. MATERIALS AND METHODS: Nodules measuring 1-3 cm in largest diameter that had been evaluated with high-resolution ultrasound (12-18 MHz) and ultrasound-guided biopsy with definitive pathologic diagnosis were analyzed. Three blinded board-certified readers evaluated high-resolution images of each nodule for jagged edges, lobulated borders, and curved borders along their margins...

The 2017 edition of the WHO book on Classification of Tumours of Endocrine Organs includes a new section entitled "Other encapsulated follicular-patterned thyroid tumours", in which the newly created NIFTP (Non-invasive follicular thyroid neoplasm with papillary-like nuclear features) is identified and detailed described. Despite deleting the word "carcinoma" from its name, NIFTP is not a benign tumor either, and is best regarded as a neoplasm with "very low malignant potential"...

Thyroid malignancies comprise only 2 per cent of all cancers. Yet the incidence of thyroid cancers has been increasing faster than other malignancies, likely due to increased screening and surveillance of thyroid nodules. The Bethesda system represents the preferred method of evaluating thyroid nodules for malignancy using fine needle aspiration (FNA). Many thyroidectomies are performed for small, asymptomatic nodules found on ultrasound. These small papillary cancers (<0.5 cm) are termed microcarcinomas and represent a more indolent natural history causing some to name them "occult papillary tumors...

Thyroid cancer management has moved to less extensive surgery in lesions with favorable criteria. Our study evaluated if the sonographic (US) size of thyroid nodules is a reliable criterion to determine the extent of surgery in patients with papillary thyroid carcinoma (PTC). A retrospective study was performed to evaluate thyroid nodules measuring <10 mm in the preop sonogram with a permanent pathology of PTC. Patients were subdivided into two groups based on the US size: A (1-5 mm) and B (6-10 mm). Statistical correlations were made for the presence of the following unfavorable criteria: multifocality, capsular invasion, angio/lymphatic invasion, extrathyroidal invasion, and presence of metastases...

We hypothesize that distinct cell phenotypes are governed by different sets of gene master regulators (GMRs) whose strongly protected (by the homeostatic mechanisms) abundance modulates most cell processes by coordinating the expression of numerous genes from the corresponding functional pathways. Gene Commanding Height (GCH), a composite measure of gene expression control and coordination, is introduced to establish the gene hierarchy in each phenotype. If the hypothesis is true, than one can selectively destroy cancer nodules from a heterogeneous tissue by altering the expression of genes whose GCHs are high in cancer but low in normal cell phenotype...

BACKGROUND: Core needle biopsy (CNB) has been used as an alternative or a complementary method for diagnosis of thyroid nodules. However, morphological analysis of the nuclear features of papillary thyroid carcinoma (PTC) cells obtained via CNB remains unclear. Hence, we examined the differences between the PTC nuclear features in CNB and thyroidectomy specimens. METHODS: Ten PTC patients, who underwent both CNB and thyroidectomy, were selected. Microscopic photographs of three representative areas of the PTC and adjacent parenchyma were taken...

Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. On the contrary, primary thyroid lymphoma (PTL) is a rare disease, accounting for 2% to 5% of all thyroid malignancies. Despite several cases in which both PTC and PTL arise in the setting of Hashimoto's thyroiditis (HT), the coexistence of both tumors in HT patients is very rare. Herein we report the case of a 66-year-old woman with long-standing nodular HT under replacement therapy, who presented with a fast, painless enlargement in the right anterior side of the neck...

BACKGROUND: Metastases to the thyroid gland are more frequent than previously thought, although most of them are occult or not clinically relevant. Overall, only 42 cases of metastases to thyroid from breast cancer have been reported thus far. Here we report the case of a patient with breast cancer metastatic to the thyroid. We also review the 42 previously reported cases (published between 1962 and 2012). This is the first review about metastases to thyroid gland from breast cancer. CASE PRESENTATION: A 64-year-old woman of Caucasian origin was diagnosed with a lobular invasive carcinoma of the breast (luminal A, stage II)...
