The bilateral axillo-breast approach (BABA) is one of the most popular contemporary remote-access thyroidectomy techniques. While the initial experiences with BABA endoscopic thyroidectomy (ET) were associated with some technical challenges and safety concerns, many limitations of the technique could now be substantially overcome by BABA robotic thyroidectomy (RT). In this review, the current literature evidences of BABA RT were analyzed. Data regarding the patient selection, the learning curve, and the comparison with open thyroidectomy (OT) and BABA ET were examined...

Anaplastic thyroid carcinoma (ATC) is a rare malignancy, accounting for 1-2% of all thyroid cancers. Although rare, ATC accounts for the majority of deaths from thyroid carcinoma. ATC often originates in a pre-existing thyroid cancer lesion, as suggested by the simultaneous presence of areas of differentiated or poorly differentiated thyroid carcinoma. ATC is characterized by the accumulation of several oncogenic alterations, and studies have shown that an increased number of oncogenic alterations equates to an increased level of dedifferentiation and aggressiveness...

Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1-3% of all ectopic thyroid tissue is located in the lateral neck. This entity may represent the only functional thyroid tissue in the body. Malignant transformation of ectopic thyroid is uncommon; but even rarer is the development of papillary carcinoma on it...

BACKGROUND AND AIMS: Clinical experience suggests that patients with coeliac disease (CD) are more prone to develop herpes zoster (HZ), but robust studies are lacking. METHODS: We identified 29,064 patients with CD 1969-2008 using biopsy report data from Sweden's 28 pathology departments. CD was equalled to villous atrophy (Marsh histopathology grade III). Each patient was matched on age, sex, calendar year and county of residence to up to five reference individuals ( n=144,342) from the general population...

BACKGROUND: Follicular variant of papillary thyroid carcinoma (FVPTC) is traditionally divided into infiltrative and encapsulated types. Adding to this classification, noninvasive follicular thyroid neoplasm with papillary like nuclear features (NIFTP) represents a reclassification of a subset of cases (encapsulated tumors without lymphovascular or capsular invasion). The purpose of this study was to assess the role of ultrasound (US) in predicting tumor invasiveness in FVPTC. METHODS: From January 2014 to May 2016, preoperative US examinations were performed on 151 patients with 152 FVPTCs who underwent surgery...

INTRODUCTION: Although pathology services focused on fine needle aspiration (FNA) biopsy of superficial palpable masses with on-site cytological evaluation are available in a wide range of clinical and academic settings, the addition of ultrasound (US) guidance into FNA practice by a cytopathologist group can be challenging. An US-FNA service provided by a cytopathologist in the department of Pathology is a relatively new practice in the field of medicine. This report summarizes our experience and strategies in achieving this objective and our successful preliminary results...

BACKGROUND: The residual tumor (R) classification describes the tumor status after therapy, which in patients with thyroid carcinomas is predominantly after surgical treatment. The aim of the R classification is to indicate the success of (surgical) therapy, which can influence further therapeutic procedures and allow relevant prognostic statements. OBJECTIVE: Definition of R1 resection as well as minimally invasive extrathyroidal growth of thyroid carcinomas as the latter is a common prerequisite for R1 resected thyroid carcinoma...

Hashimoto's thyroiditis (HT) seems to have favourable prognostic impact on papillary thyroid cancer (PTC), but data were obtained analyzing all disease stages. Given that HT-related microenvironment involves solely the thyroid, we aimed to assess relationship between HT, as detected through pathological assessment, and outcome in intrathyroidal PTC. This was a multicenter, retrospective, observational study including 301 PTC with no evidence of extrathyroidal disease. Primary study endpoint was the rate of clinical remission...

This 48-year-old-man who had undergone right thyroid lobectomy for undifferentiated thyroid carcinoma nine years earlier developed generalized seizures. His cerebrospinal fluid was xanthochromic with elevation of total protein. Computed tomography (CT) showed mixed-density bilateral ventricular masses. Magnetic resonance imaging (MRI) revealed multiple nodules in both lateral ventricles; they were heterogeneously enhanced by gadolinium. Diffuse hyperintensity in the right medial temporal lobe and bilateral subependymal area was noted on fluid-attenuated inversion recovery images...

There is a frequently encountered subset of hypothyroid patients who are refractory to standard thyroid hormone replacement treatment and require unexpectedly high doses of levothyroxine. In addition to clinical situations where hypothyroid patients are non-compliant, or where there is the possibility of excipient-induced disease exacerbation (gluten/celiac disease), therapeutic failure may be due to impaired absorption of the administered drug. The common approach to managing patients with unusual thyroxine needs is to escalate the dose of levothyroxine until targeted TSH levels are achieved...

This study reports a case of nodular fasciitis incidentally detected in a patient with papillary thyroid cancer. A 47-year-old woman underwent a total thyroidectomy and radioactive iodine therapy for papillary thyroid cancer. On a follow-up fluorodeoxyglucose ((18)F-FDG) PET/computed tomography (CT) scan after 12 months, a focal (18)F-FDG-avid lesion was incidentally detected in the paraspinal muscle. It was well-enhanced on CT and magnetic resonance imaging, indicating metastasis. However, the lesion was not iodine avid on the (123)I whole body scan, which favored benign etiology over metastasis from thyroid cancer...

We aimed to evaluate the diagnostic values of conventional ultrasound (US), ultrasound contrast (UC) and ultrasound elastography (UE) in distinguishing the benign and malignant thyroid nodules. A total of 100 patients with thyroid nodules receiving operative treatment were selected; they underwent the conventional US, UE and UC examinations before operation, respectively. The nodules received pathological examination after operation to distinguish benign from malignant lesions. The sensitivity, specificity and diagnostic accordance rate of each diagnostic method was evaluated by receiver operating characteristic (ROC) curve, and the area under the curve (AUC) of ROC was calculated...

BACKGROUND: The incidence of well-differentiated thyroid cancer (WDTC) is increasing. Patients with higher socioeconomic status have higher rates of WDTC, possibly due to increased imaging and overdiagnosis. We compared methods of WDTC diagnosis in patients treated at a public and an adjacent private university hospital. MATERIALS AND METHODS: Patients with WDTC at the two hospitals between 2004 and 2010 were included. Patients were categorized into having their WDTC discovered on physical examination or on unrelated imaging...
