title: [Hypofunctional thyroid tumor].
abstract: Fine needle aspiration biopsy is considered to be the most valuable tool in the preoperative diagnosis of papillary thyroid carcinoma but the diagnostic criteria have to be strictly applied to avoid unnecessary surgery. In cases of cellular and encapsulated thyroid tumor serial sections from the tumor capsule should to be taken to exclude capsular and/or vascular invasion.
