Immunohistochemistry as alternative to DNA sequencing in detection of BRAF V600E mutation in papillary thyroid carcinomas

Paja Miguel , Del Cura Jose L , de Ciriza Maite Perez , Oleaga Amelia , Ugalde Aitziber

Objective: To compare the results of immunohistochemistry (IHC) and DNA sequencing in detection of BRAF V600E mutation in papillary thyroid carcinomas (PTC). BRAF V600E mutation is the most common genetic alteration in papillary thyroid carcinomas and is associated with worse prognosis. Direct sequencing is usually performed, but less expensive immunohistochemistry can be used instead.Methods: Study was performed in 54 consecutive PTCs during 2014–2...

In our centre, thyroid core-biopsy (CB) has replaced fine needle aspiration biopsy (FNAB) in the study of thyroid nodules because its better accuracy. International guidelines recommend repeating the FNA in cases of inadequate or insufficient first specimen, but nothing is published about the case in failed CB.Objective: To study the differences between nodules with inadequate and diagnostic thyroid Core Biopsy and the accuracy of repeating a CB after a ...

The clinical significance and potential morbidity of papillary thyroid microcarcinomas (PTMC) is discussed. Particularly the differences between those PTMC identified postoperatively in histological examination (incidentals), and those diagnosed preoperatively (non-incidentals). We retrospectively analysed differences in clinical presentation and course after treatment in these two groups. The study population consisted of 199 patients with PTMC who underwent surgery from 2000...

Introduction: BRAF(V600E) mutation has received great attention to improve risk stratification in patients with PTC. Its prognostic value in the different Cytological variants (CytV) of PTC is not well established. The aim of this study was to investigate differences in clinicopathological features according to CytV, among patients harbouring the mutation.Methods: We evaluated 102 patients with pathological diagnosis of PTC. All of them underwent total t...

Coexistence of thyrotropinoma and chronic autoimmune thyroiditis, a diagnostic challenge

Olaizola Izaskun , Egana Nerea , Bilbao Ismene , de Ciriza Maite Perez , Antunano Maria Luisa , Elias Estela , Garcia Cristina , Aranburu Maite , Yoldi Alfredo , Goena Miguel Maria

Introduction: TSHomas are rare TSH producing tumors, whereas chronic autoimmune thyroiditis is a frequent condition. Patients with TSHoma are characterized by increased circulating levels of peripheral thyroid hormones, but when a chronic autoimmune thyroiditis is associated, they may be normal or low, making the diagnosis challenging.Case report: A 55 year-old woman, with previous medical history of obesity and impaired fasting glucose, was diagnosed of...
