Follicular patterned nodules are sometimes complex to be classified due to ambiguous nuclear features and/or questionable capsular or vascular invasion. In this setting, there is a poor inter-observer concordance even among expert pathologists. Raman spectroscopy was recently used to separate benign and malignant thyroid nodules based on their molecular fingerprint; anyway, some histologically proved follicular adenomas were clustered as having a characteristic profile of malignant lesions.

Medullary thyroid carcinoma is an aggressive tumor and presents with significant morbidity and mortality and a high rate of lymph node metastases. The combination of total thyroidectomy and cervical lymphadenectomy is the essential treatment for those patients presenting with cervical lymph node metastases.

Introduction: Breast metastases although rare are challenging for diagnostic difficulties and management. Treatment differs according to morphological, immunophenotipycal and biologic features of the primary tumor and their general behaviour is extremely different compared to primary breast cancer. The most frequent primary tumors include melanoma, lymphomas, gynecological, pulmonary, head and neck, gastroenteric and urinary tract cancers.

Establishment and maintenance of the apical-basal cell polarity, required for proper replication, migration, specialized functions and tissue morphogenesis, relies on three evolutionary conserved complexes: PAR, CRUMBS and SCRIBBLE. Loss of cell polarity/cohesiveness (LOP/C) is implicated in cancer progression, and members of the polarity complex have been described as either oncogenes or oncosuppressors. However, no information on their role in thyroid cancer (TC) progression is available. In the present study, we evaluated the gene expression of the PAR complex members aPKC?, PARD3?/?

Background Programmed death 1 (PD-1) inhibitors are frequently associated with thyroid-related adverse events (TAEs), but many aspects remain unclear. This study aims to evaluate the incidence and characteristics of such events and to find any predictive factor for its development. Methods We retrospectively analysed data from patients with advanced solid tumours (non-small-cell lung carcinoma, renal cell carcinoma, metastatic melanoma) treated with PD-1 inhibitors (nivolumab, pembrolizumab) in Oncology Unit B, Policlinico Umberto I of Rome, from June 2015 to December 2018.

Background: Thyroid fine-needle aspiration (FNA) is a reliable and cost-effective diagnostic tool for establishing the nature of thyroid nodules, although up to 30% of FNAs are still classified as “indeterminate.” Molecular testing of FNAs could improve preoperative diagnosis, thereby reducing unnecessary surgery. In this multicenter prospective study the authors investigated, using a 7-gene assay, the distribution and diagnostic impact of BRAF, RAS, RET/PTC, and PAX8/PPARg, the most frequent genomic alterations occurring during thyroid oncogenesis.

Background: Italian consensus for the classification and reporting of thyroid cytology
(ICCRTC) has been used in almost all Italian institutions since 2014. High reliability
of ICCRTC in classifying low and high risk indeterminate nodules (Tir 3A and Tir 3B,
respectively) was demonstrated. Here we reviewed our casuistry of thyroid indeterminate
lesions to analyze the histologic outcome.
Methods: All lesions undergone FNA and final histology at S. Andrea Hospital of Rome
