Objectives: Signet ring cells (SRCs) can be seen in a variety of thyroid tumors and can pose a diagnostic pitfall on cytology. This study describes the cytologic, histomorphologic, and molecular aspects of a cohort of primary thyroid tumors with SRCs. Methods: A search was performed of the Massachusetts General Hospital and Brigham and Women's Hospital (Boston, MA) pathology archives for the keywords thyroid, signet, and signet ring features between 2000 and 2014...

Chinna Naik, Sandip Basu
Malignant involvement of thyroglossal duct cyst is rare, still rarer is the synchronous malignant involvement of the thyroid gland. Although the Sistrunk procedure is often regarded as adequate, controversy exists of the need for an additional total thyroidectomy and radioiodine ablative therapy, the decision of which depends upon the presence of (i) suspicious thyroid gland nodule; (ii) presence of lymphadenopathy; or (iii) a previous history of neck irradiation. We report a 47-year-old woman diagnosed with papillary carcinoma within a recurrent thyroglossal duct cyst with infiltration into surrounding soft tissues and a suspicious thyroid nodule of the left thyroid lobe with no regional lymph node involvement...

BACKGROUND & OBJECTIVE: Thyroid nodules are very common in our setup and their diagnosis on fine needle aspiration is not easy and is a taxing affair. It is a challenge to differentiate between follicular adenoma and follicular carcinoma without histology. Our objective was to investigate the role of Galectin-3 in fine needle aspirates of thyroid nodules as a prospective diagnostic marker and consequently its ability to differentiate benign from malignant neoplasms. METHODS: The research was conducted at the department of Pathology, King Edward Medical University, in association with other teaching institutions of Lahore from June 2012 to July 2014...

OBJECTIVES: CD43 is normally expressed only on the surface of leukocytes, and is considered a sensitive and specific marker for hematologic malignancies. As such, it may have diagnostic utility in confirming hematolymphoid lineage in cases that are negative for CD45. Aberrant CD43 expression has been described in non-hematopoietic tumors, although literature data on this topic is variable and sometimes contradictory. To clarify and expand on existing literature findings, we evaluated CD43 expression by immunohistochemistry (IHC) in a large cohort (307) of non-hematopoietic neoplasms, including poorly differentiated malignancies...

BACKGROUND: The newly termed tumor 'noninvasive follicular thyroid neoplasm with papillary-like nuclear features' (NIFTP) acts in an indolent manner and can likely be safely managed with a thyroid lobectomy. Preoperative fine-needle aspiration (FNA) is the cornerstone of surgical planning, but the ability of FNA to distinguish NIFTP from other variants of papillary thyroid carcinoma (PTC) has not been well-evaluated. METHODS: A 9-year retrospective review of the preoperative cytology and surgical pathology of PTC patients who underwent a thyroidectomy at our tertiary referral center...

The encapsulated and noninvasive follicular variant of papillary thyroid carcinoma has been recently reclassified as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). These tumors demonstrate indolent behavior. This change in nomenclature will have great clinical impact by avoiding overtreatment of patients with NIFTP lesions who in the past were diagnosed with thyroid carcinoma and typically received completion thyroidectomy followed by radioactive iodine ablation. The pathologic diagnosis of NIFTP requires surgical removal of the thyroid lesion or the lobe harboring it, and thorough sampling of the complete interface between the tumor capsule and the thyroid parenchyma, to exclude foci of invasion...

Chest wall tumors are relatively rare, and hematogenous metastasis to the chest wall is very rare. We herein describe a rare case of occult thyroid carcinoma as metastasis to the chest wall in an 80-year-old woman. The patient received detailed examinations of the chest wall tumor, and the results suggested that she had occult thyroid carcinoma. Surgery was then performed to remove all of her thyroid. As a result, she was diagnosed with follicular carcinoma of the thyroid. We report an extremely rare case of occult thyroid carcinoma diagnosed as hematogenous metastasis to the chest wall...

AIM: To evaluate the clinical significance of farnesoid X receptor (FXR) in thyroid neoplasia. PATIENTS & METHODS: FXR expression was assessed immunohistochemically on 88 thyroid neoplastic tissues (benign = 44, malignant = 44). RESULTS: Enhanced FXR was more frequently observed in papillary carcinomas compared with hyperplastic nodules (p = 0.0489). In malignant lesions, elevated FXR was associated with capsular (p = 0.0004) and vascular invasion (p = 0...

The most common endocrine malignancy is thyroid cancer, and researchers have made a great deal of progress in deciphering its molecular mechanisms in the recent years. Many of molecular changes observed in thyroid cancer can be used as biomarkers for diagnosis, prognosis, and therapeutic targets for treatment. MicroRNAs (miRNAs) are important parts in biological and metabolic pathways such as regulation of developmental stages, signal transduction, cell maintenance, and differentiation. Therefore, their dysregulation can expose individuals to malignancies...

As Dr. Rosario pointed out, it might be more useful to differentiate NIFTP from invasive encapsulated follicular variant of papillary thyroid carcinoma (iE-FVPTC), not from infiltrative FVPTC (I-FVPTC) in clinical setting since infiltrative FVPTCs show overt malignant US features more frequently. However, in the previous study, we attempted to describe the characteristic ultrasound (US) features and diagnostic method of NIFTP specifically. This article is protected by copyright.

BACKGROUND: Data relating the size of thyroid cancer with histological types and variants are scarce. METHODS: All incident thyroid cancer diagnosed between 2003 and 2012 in a mildly iodine-deficient area were derived from a population-based tumor registry. Undifferentiated/anaplastic thyroid cancer and incidental cases were excluded. Major diameter of thyroid cancer, as assessed by pathological examination, was stratified in classes: ≤10 mm; 11-20 mm; 21-40 mm; and >40 mm...

We previously reported that ABI3 expression is lost in follicular thyroid carcinomas and its restoration significantly inhibited cell growth, invasiveness, migration, and reduced tumor growth in vivo. The mechanistic basis by which ABI3 exerts its tumor suppressive effects is not fully understood. In this study, we show that ABI3 is a phosphoprotein. Using proteomic array analysis, we showed that ABI3 modulated distinct cancer-related pathways in thyroid cancer cells. The KEA analysis found that PI3K substrates were enriched and forced expression of ABI3 markedly decreased the phosphorylation of AKT and the downstream-targeted protein pGSK3β...

BACKGROUND AND OBJECTIVE: Chemokine (C-C motif) ligand (CCL)2, the prototype Th2 chemokine, is secreted by tumor cells, and has growth promoting effects. Whether CCL2 protumorigenic activities will be validated, then CCL2 and its receptor CCR2 may be therapeutic targets in cancer. METHODS: We tested in "primary human anaplastic thyroid carcinoma (ATC) cells" (ANA) versus "normal thyroid follicular cells" (TFC): a) CCL2 secretion basally, after IFN-g and/or TNF-a stimulation; b) PPARg activation by thiazolidinediones (TZDs), rosiglitazone or pioglitazone, on CCL2 secretion, and on proliferation and apoptosis in ANA...

BACKGROUND: Transoral thyroid surgery is an ideal method for minimally invasive thyroidectomy, as there is less flap dissection during the procedure and no postoperative scars. Nonetheless, technical obstacles have precluded the wide dissemination of this procedure. We present the surgical procedures and outcomes of transoral robotic thyroidectomy (TORT). METHODS: From September 2012 to June 2016, we performed TORT at Korea University Hospital. We used three intraoral ports and a single axillary port for the system's four robotic arms...

Papillary thyroid carcinoma (PTC) is the most common thyroid cancer with multiple risk factors including exposure to ionising radiation. Oestrogens contribute to papillary carcinoma development by promoting cell proliferation and invasion of mutated epithelial follicular cells. The present study aimed to assess ER-α and PR expression in PTC and to correlate their expression with the clinicopathological parameters in this cancer. This study included 62 primary and six metastatic papillary thyroid carcinoma cases...

Differentiated thyroid carcinoma of follicular cell-derivation is the most common endocrine neoplasm with a rapidly increasing incidence. The majority represent papillary carcinomas; more rarely, they are follicular carcinomas. The vast majority have indolent behavior, however a significant proportion progress to develop lymph node metastases and a smaller proportion disseminate systemically. While common and frequent genetic events have been described to underlie the development of these neoplasms, the factors contributing to differing behaviors among tumors with similar genetic alterations remain unclear...

Despite the relatively high prevalence of thyroid cancer, the occurrence of multiple synchronous, distinct subtypes of primary thyroid carcinoma is uncommon. The incidental finding of papillary thyroid microcarcinoma in a gland with a biologically relevant follicular or medullary carcinoma is more frequent than the synchronous occurrence of multiple clinically significant carcinomas. We report a case of synchronous papillary and follicular thyroid carcinomas metastatic to lymph node and bone, respectively. Next generation sequencing showed BRAF V600E mutation in the primary papillary carcinoma and NRAS Q61R mutation in the primary follicular carcinoma and bony metastasis...

Distinguishing follicular carcinoma from follicular adenoma, based on cytomorphological features, has always been challenging to cytopathologists. Identification of biomarkers for improving diagnostic accuracy is important for clinical management. Meanwhile, it is critical to identify therapeutic target candidates for treatment of follicular carcinoma. Currently, no reliable diagnostic protein biomarkers and therapeutic targets are available. To explore novel protein biomarker and therapeutic target candidates, a liquid chromatography-tandem mass spectrometry approach was applied to analyze control, follicular adenoma, and follicular carcinoma using formalin-fixed, paraffin-embedded tissue samples...

Papillary thyroid carcinoma is the most common neoplasm of the thyroid gland which is usually associated with a very good prognosis. The aim of this case report is to present the disease course of a rare tumor of the thyroid gland, which is worthwhile due to its extraordinary appearance and specific management. A 46-year-old patient presented with a pronounced right-sided, but bilateral, multinodular goiter, with a volume of approximately 80 mL, as assessed on ultrasonography. Surgical removal was indicated as scintigraphy showed a 4-cm cold nodule that almost completely took up the right thyroid lobe...
