Clinico-pathological factors and [F]FDG PET/CT metabolic parameters for prediction of progression-free survival in radioiodine refractory differentiated thyroid carcinoma.

Objective: Identifying prognostic markers for clinical outcomes is crucial in selecting appropriate treatment options for patients with radioiodine-refractory (RAI-R) differentiated thyroid carcinoma (DTC). The aim of this study was to investigate the prognostic value of clinico-pathological features and semiquantitative [F]FDG PET/CT metabolic parameters in predicting progression-free survival (PFS) in DTC patients with RAI-R.

Patients And Methods: This prospective cohort study included 110 consecutive RAI-R DTC patients who were referred for [F]FDG PET/CT imaging.

A Rare Case of Functional Metastatic Follicular Thyroid Carcinoma With Concomitant Thyrotoxicosis.

We report a case of a 60-year-old lady with metastatic follicular thyroid carcinoma (FTC) who was presented with thyrotoxicosis and heart failure symptoms after total thyroidectomy. Clinical features and investigations led to the diagnosis of functional metastatic FTC with concomitant thyrotoxicosis. Levothyroxine therapy was stopped, and she was treated with propylthiouracil (PTU) followed by serial radioiodine treatments (RAITs) with good control of thyrotoxicosis and metastases.

Insights into thyroid and salivary gland cytopathology: highlights from a 45th ECC slide seminar.

Introduction: Thyroid and salivary gland cytopathology frequently present diagnostic challenges due to complex presentations, overlapping features between benign and malignant conditions, particularly with grey-zone entities and rare pathologies. To address these issues, the 45th European Congress of Cytology (ECC) held a slide seminar focused on challenging cases. This article reviews key findings from the six cases discussed, emphasizing the importance of a comprehensive diagnostic approach.

Spatially Resolved Molecular Characterization of Noninvasive Follicular Thyroid Neoplasms with Papillary-like Nuclear Features (NIFTPs) Identifies a Distinct Proteomic Signature Associated with RAS-Mutant Lesions.

Follicular-patterned thyroid neoplasms comprise a diverse group of lesions that pose significant challenges in terms of differential diagnosis based solely on morphologic and genetic features. Thus, the identification of easily testable biomarkers complementing microscopic and genetic analyses is a highly anticipated advancement that could improve diagnostic accuracy, particularly for noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTPs). These tumors exhibit considerable morphological and molecular heterogeneity, which may complicate their distinction from structurally similar neoplasms, especially when genetic analyses reveal shared genomic alterations (e.

Could Be a Promising Marker for Preoperative Diagnosis of High-Grade Papillary Thyroid Carcinoma?

Background/objectives: A modern classification distinguishes between two nosological entities posing an intermediate risk between differentiated and anaplastic carcinoma: poorly differentiated thyroid carcinoma and differentiated high-grade thyroid carcinoma. There are currently few studies searching for the preoperative molecular genetic markers of high-grade papillary thyroid carcinoma (PTC HG), primarily because of a recent WHO reclassification and singling out of a separate entity: high-grade follicular cell-derived nonanaplastic thyroid carcinoma. Therefore, this work was aimed at identifying PTC HG-specific microRNAs and mRNAs that reliably distinguish them from differentiated papillary thyroid carcinoma in preoperative cytology specimens (fine-needle aspiration biopsies).

A gigantic intraosseous and dural-based calvarial metastatic follicular thyroid carcinoma: illustrative case.

Background: Metastatic follicular thyroid carcinoma to the central nervous system (CNS), including the skull and dura, is exceedingly rare.

Observations: The authors present the case of a gigantic, intraosseous, dural-based follicular thyroid carcinoma, highlighting the operative strategy for this mass. They also provide a literature review of CNS metastases of differentiated thyroid carcinoma.

Navigating diagnostic dilemmas: Localizing parathyroid adenoma in the presence of MIBI-avid thyroid nodules: A case report and literature review.

Surgery is the preferred treatment for primary hyperparathyroidism (PHPT), but the presence of MIBI-avid thyroid nodules can complicate the localization of parathyroid adenoma (PA). In this case report, we discuss the role of imaging in localizing PA in a patient with concurrent thyroid nodules. A 49-year-old female presented with hypercalcemia and elevated parathyroid hormone levels.

Role of clinicopathologic and sonographic characteristics for the management of patients with cytological diagnosis of thyroid follicular neoplasm.

Background: Thyroid cancer is one of the most common endocrine tumors and preoperative diagnosis of thyroid follicular neoplasm (FN) is challenging. Commonly used examination methods have difficulty in distinguishing thyroid cancer from other follicular lesions. At the same time, with the recently released World Health Organization (WHO) guidelines, the risk classification of FNs of the thyroid is a new enlightenment for clinicians in the diagnosis and treatment.

Intratumoral and peritumoral radiomics based on ultrasound for the differentiation of follicular thyroid neoplasm.

Background: Although ultrasound (US) has been widely adopted as the preferred imaging modality for thyroid nodule evaluation, its reliability in distinguishing follicular adenomas from adenocarcinomas based on US features has been a subject of debate. The primary objective of our study was to comprehensively evaluate the efficacy of US-derived intratumoral and peritumoral radiomics in preoperatively differentiating follicular thyroid adenomas from adenocarcinomas, thereby contributing to the ongoing discussion regarding this challenging distinction.

Methods: In total, 195 patients who were pathologically diagnosed with thyroid follicular neoplasm were retrospectively enrolled in this study.

Axillary Reactive Lymphoid Hyperplasia, Likely Due to Unicentric Castleman Disease, and the Concurrent Presence of Orbital Mucosa-Associated Lymphoid Tissue (MALT) Lymphoma: A Six-Year Follow-Up Study.

Castleman disease is a lymphadenopathy of unknown cause at a single site, which is designated as unicentric Castleman disease, or at multiple sites designated as multicentric Castleman disease. We present a patient who showed axillary reactive lymphoid hyperplasia, likely due to unicentric Castleman disease, and orbital extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma in a six-year follow-up. A 76-year-old man had a painless left axillary mass for an unknown period and also left complete blepharoptosis with no other systemic symptoms.

[Pancreatic cystic neoplasms: work-up and surveillance].

Whereas pancreatic masses are often difficult to detect with transabdominal ultrasound, cross-sectional imaging features high sensitivity for the pancreatic tumors. However, increasing availability of magnetic resonance imaging (MRI) has led to a surge in the detection of benign or precancerous pancreatic lesions. The medical history is characteristic only for two entities.

[A Somehow Different Cause of an Upper Gastrointestinal Bleeding].

We report a case of an 89-year-old patient, who presented with melena and physical degradation at the emergency department. As cause for his symptoms, we found an upper GI-bleeding from a metastasis of a follicular thyroid carcinoma, for which the patient was surgically treated in the year 1996.

Presentation and Management of Highly Differentiated Follicular Carcinoma of Ovarian Origin With Gene Variants.

Struma ovarii (SO) is a rare subtype of ovarian teratoma composed of more than 50% thyroid tissue. Extraovarian spread of SO, called peritoneal strumosis, was previously considered benign given the lack of histological malignant features. However, the 2020 World Health Organization Classification of Female Genital Tumors reclassified peritoneal strumosis as highly differentiated follicular carcinoma of ovarian origin (HDFCO), highlighting its low-grade malignant potential.

Spinal metastases in primary thyroid malignancies: Single center experience of 44 cases.

Background: Patients with differentiated thyroid carcinoma have a 10 year survival rate of more than 95%. However, the existence of spinal metastases significantly reduces overall survival. In this study, we review the epidemiology and outcomes of patients with thyroid malignancies with spinal metastases.
