Aim of the study was to evaluate whether clinical parameters and echographic patterns may be predictive of malignancy in thyroid nodules with a cytological diagnosis of follicular (FOL) and H?rthle cell (HC) neoplasia. The study included 495 patients (388 F: mean age 45±14 yr; 107 M: mean age 46±14 yr) with FOL (n=418) and CH (n=77) nodules, ‘cold’ at scintiscan and undergone to thyroidectomy. Clinical parameters considered were: sex, age, goi...

Aim of the study was to establish the diagnostic value of nuclear atypia thyroid nodules with cytological diagnosis of follicular (FOL) and Hv¨rthle cell (HC) neoplasia. 1039/23.313 fine needle aspiration (FNA) performed in January 2002 June 2005 in the Department of Endocrinology, University of Pisa had cytological diagnosis of FOL e CH. FNA was performed under echo guidance, using 23 gauge needle attached to 10 mL syringe. The material was air-dryed and stained with Pap...

Mutations in the RET proto-oncogene are responsible for multiple endocrine neoplasia type II. Somatic RET mutations were described in 50% of medullary thyroid carcinoma (MTC). We describe here a novel germline mutation of the RET gene detected in an apparentely sporadic MTC.The index case was a 67 years old patient who arrived at our observation for a bilateral laterocervical linfoadenopathy. The patient was clinically evaluated for thyroid function and ...
