    Synchronous malignancies of thyroglossal duct cyst and thyroid gland.
    Natl Med J India 2017 Mar-Apr;30(2):76-77
    Radiation Medicine Centre (Bhabha Atomic Research Centre), Tata Memorial Hospital Annexe, Jerbai Wadia Road, Parel, Mumbai, Maharashtra 400012; Homi Bhabha National Institute, Mumbai, Maharashtra, India.
    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.

    Accounting for tissue heterogeneity in infrared spectroscopic imaging for accurate diagnosis of thyroid carcinoma subtypes.
    Vib Spectrosc 2017 Jul 16;91:77-82. Epub 2016 Sep 16.
    Department of Pathology, University of Illinois at Chicago, 840 S Wood St. 130 CSN, Chicago, IL 60612, USA.
    Fourier transform infrared (FT-IR) microscopy was used to image tissue samples from twenty patients diagnosed with thyroid carcinoma. The spectral data were then used to differentiate between follicular thyroid carcinoma and follicular variant of papillary thyroid carcinoma using principle component analysis coupled with linear discriminant analysis and a Naïve Bayesian classifier operating on a set of computed spectral metrics. Classification of patients' disease type was accomplished by using average spectra from a wide region containing follicular cells, colloid, and fibrosis; however, classification of disease state at the pixel level was only possible when the extracted spectra were limited to follicular epithelial cells in the samples, excluding the relatively uninformative areas of fibrosis.

    The Molecular Landscape of Noninvasive Follicular Thyroid Neoplasm With Papillary-like Nuclear Features (NIFTP): A Literature Review.
    Adv Anat Pathol 2017 Sep;24(5):252-258
    *Department of Surgical, Medical, Molecular Pathology and Critical Area, University of Pisa †Unit of Pathological Anatomy, 3rd Division, University Hospital of Pisa, Pisa, Italy ‡Department of Pathology, Queen Alexandra Hospital, University of Portsmouth, Portsmouth, UK §Department of Pathology and Laboratory Medicine, Hospital of the University of Pennsylvania, Perelman School of Medicine, Philadelphia, PA.
    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.

    Letter to the Editor: Reply to "Ultrasonography and cytology as predictors of noninvasive follicular thyroid (NIFTP) neoplasm with papillary-like nuclear features: importance of the differential diagnosis with the invasive encapsulated follicular variant of papillary thyroid cancer".
    Clin Endocrinol (Oxf) 2017 Jul 26. Epub 2017 Jul 26.
    Department of Radiology and Center for Imaging Science, Thyroid Center, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81, Irwon-ro, Gangnam-gu, Seoul, 06351, Korea.
    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. Read More

    The influence of the noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) resection diagnosis on the false-positive thyroid cytology rate relates to quality assurance thresholds and the application of NIFTP criteria.
    Cancer 2017 Jul 5. Epub 2017 Jul 5.
    Department of Pathology, University of Pittsburgh Medical Center-Presbyterian, Pittsburgh, Pennsylvania.
    Background: Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is a newly defined entity and recent studies have suggested a decrease of a few percentage points in the rate of malignancy (ROM) for the positive-for-malignancy (PFM) cytology category as a result of NIFTP implementation. However, the distinction between a diagnosis of PFM and one of suspicious for malignancy (SFM) may depend on a variety of factors. In the current study, the authors investigated the ROM for the PFM and SFM diagnoses before and after histologic NIFTP reclassification. Read More

    Previous data has shown that the risk of nodal metastases is significantly greater for classical papillary thyroid carcinoma (PTC) as compared to the follicular variant (FVPTC). Given a recent change in diagnostic paradigm and definition of the noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) we intended to investigate if there remains a significant difference in nodal involvement between classical PTC and FVPTC. A 6-year retrospective review of all cases with FVPTC in the diagnostic line from the University of Utah/ARUP Laboratories was conducted. Read More

    Correlation between BRAF (V600E) mutation and clinicopathological features in pediatric papillary thyroid carcinoma.
    Sci China Life Sci 2017 Jul 15;60(7):729-738. Epub 2017 Jun 15.
    Otolaryngology, Head and Neck Surgery, Beijing Children's Hospital, Capital Medical University, National Center for Children's Health, Beijing, 100045, China.
    In adults, the presence of the BRAF (V600E) mutation in papillary thyroid cancer (PTC) has been demonstrated to be strongly associated with aggressive cancer-cell characteristics and poor patient prognosis. In contrast, the frequency of this mutation in pediatric PTC has undergone limited study, and the few available estimates range from 0 to 63%. Furthermore, the role of the BRAF (V600E) mutation in pediatric PTC is controversial; thus, the present study aimed to investigate the prevalence and role of the BRAF (V600E) mutation in 48 pediatric patients with PTC, aged 3-13 years.

    C Cell and Follicular Epithelial Cell Precursor Lesions of the Thyroid.
    Arch Pathol Lab Med 2017 Jun 23. Epub 2017 Jun 23.
    Context: - The identification of precursor or dysplastic lesions in the thyroid is difficult. Pathology of the C cell has been extensively studied, and the preneoplastic nature of C-cell hyperplasia in the setting of familial medullary thyroid carcinomas is well established. However, the distinction between neoplastic and physiologic/reactive C-cell hyperplasia remains a challenge. Read More

    RAS-positive thyroid nodules.

    Thyroid Section, Division of Endocrinology, Diabetes and Hypertension, The Brigham and Women's Hospital and Harvard Medical School, Boston, Massachusetts, USA.
    Purpose Of Review: The current review focuses on the uncertainty regarding the management of rat sarcoma viral oncogene homolog RAS-positive thyroid nodules. The application of oncogene testing has been heralded for improving risk assessment for indeterminate cytology thyroid nodules and has grown in clinical use. RAS mutations are historically considered oncogenic. Read More

    Accuracy of Fine Needle Cytology in Histological Prediction of Papillary Thyroid Carcinoma Variants: a Prospective Study.

    Clinical Cytopathology Service, Institute of Pathology, via A. Franzoni - 45, 6601, Locarno, Switzerland.
    Fine needle cytology (FNC) is a crucial procedure in the preoperative diagnosis of thyroid tumors. Papillary thyroid carcinoma (PTC), in its classic variant (cPTC), is the most common malignant neoplasm of the thyroid. Several histological variants of PTC have been described, each one with its own characteristics and prognosis. Read More

    Poorly differentiated thyroid carcinoma: A hospital-based clinicopathological study and review of literature.

    Introduction: Poorly differentiated thyroid carcinoma (PDTC) is a rare aggressive malignancy of thyroid follicular cells and has unique features in morphology and behavior. This study was aimed to describe the experience of a tertiary medical center with PDTC within a 10-year period.

    Materials And Methods: This is a descriptive retrospective study of eight cases of PDTC among 418 various thyroid carcinomas. Read More

    The absence of CD56 expression can differentiate papillary thyroid carcinoma from other thyroid lesions.
    Indian J Pathol Microbiol 2017 Apr-Jun;60(2):161-166
    Department of Pathology, "Victor Babes" University of Medicine and Pharmacy, Timisoara, Romania.
    Context: The neural cell adhesion molecule CD56 is an antigen important for the differentiation of the follicular epithelium. Recent studies have reported low or absent expression of CD56 in papillary thyroid carcinoma (PTC) and its presence in normal thyroid tissue, benign thyroid lesions, and most follicular non-PTC tumors.

    Aim: We wish to estimate the value of CD56 in the differentiation of PTC (including follicular variant-PTC [FV-PTC]) from other nontumoral lesions and follicular thyroid neoplasias. Read More

    Pediatric follicular thyroid carcinoma - indolent cancer with low prevalence of RAS mutations and absence of PAX8-PPARG fusion in a Japanese population.
    Histopathology 2017 Jun 16. Epub 2017 Jun 16.
    Department of Pathology, University of Yamanashi, Yamanashi, 409-3898, Japan.
    Background: Pediatric follicular thyroid carcinomas are uncommon and their clinicopathological features and molecular profiles are still unknown. In this present study, we aimed to investigate the clinicopathological aspects of a large series of follicular thyroid carcinomas (FTCs) in pediatric patients and to analyse the point mutations in codons 12, 13 and 61 of NRAS, HRAS and KRAS genes and the rearrangements of PAX8-PPARG.

    Methods: A total of 41 pediatric FTCs less than 21 years of age were enrolled in the present study. Read More

    Papillary thyroid carcinoma expressing CD20.
    Pathol Int 2017 Jul 15;67(7):350-354. Epub 2017 Jun 15.
    Department of Pathology, Kurume University School of Medicine, Fukuoka, Japan.
    We identified a case of lymphadenopathy of metastatic papillary thyroid carcinoma (PTC) with CD20 expression, which was also expressed by the primary tumor. CD20 expression was identified using immunohistochemistry (IHC) in metastatic PTC biopsy samples from a 58-year-old woman. CD20 expression was initially determined using a CD20-recognizing L26 clone.
