[Hürthle cell neoplasms of the thyroid gland]

From 1986 to 1996 the Authors have surgically treated 34 patients affected with Hürthle cell neoplasm of the thyroid (23 benign and 11 malignant). Preoperative diagnosis was obtained mainly by fine needle aspiration biopsy. In thyroid surgery we routinely prepare laryngeal nerve and take great care to avoid devascularization fo the parathyroid glands. Operative procedures performed were hemithyroidectomy plus isthmectomy (18), subtotal thyroidectomy (2) and total thyroidectomy (14). No cervical lymph node dissection was requested, neither we observed post-operative morbidity. Mean follow-up was 116 months. During observation period we documented. No hematogenous metastasis was observed. All patients are now well and alive free of disease. This series stresses the favourable behavior of Hürthle cell neoplasm of the thyroid--even through a prolonged follow-up. A thorough review of the Literature on the topic is conducted. The Authors are in favour of total thyroidectomy as first choice procedure for lesions larger than 40 mm in order to reduce the need of completion thyroidectomy and the potential morbidity.
