[Thyroid cancer treatment].

INTRODUCTION: Thyroid diseases are common although cancer is rare. There are some controversial issues concerning the extent of surgical treatment of thyroid cancer. MATERIALS AND METHODS: We have studied 614 cases of thyroidectomy inducing 82 of mostly papillary and follicular thyroid cancers. RESULTS AND DISCUSSION: We observed that differentiated thyroid cancer has a predilection for the right lobe and one third of papillary tumors are multifocal. We have seen that fine needle aspiration cytology is the most useful preoperative study. Intraoperative frozen biopsy has a good specificity but sensitivity is low in our series, specially for follicular neoplasms. The treatment in our series consisted in total thyroidectomy and, in differentiated cancers, postoperative I-131. Survival is very good for differentiated cancers. Prognosis is poor for anaplastic carcinoma in the short term.

[Carotid thrombosis as the clinical onset of cervical metastasis of unknown origin].

Carotid infiltration by a cervical metastatic node, although uncommon, has a poor prognosis and controversial treatment. We report the case of a 59-year-old male patient with a metastatic node of squamous cell carcinoma of unknown origin and a clinical onset in the form of ischemic cerebrovascular accident caused by ipsilateral occlusion of the internal carotid. Radical neck dissection was performed, sparing the carotid artery, which was not infiltrated by the tumor. The pathogenesis of carotid occlusion is discussed and the literature reviewed.
