title: [Thyroidal oxyphilic tumors].
abstract: Treatment of thyroidal oxyphilic (Hurthle cell) tumors is controversial due to difficulties in grading tumor malignancy. We classify these tumors into 3 histological subtypes: adenomas, atypical adenomas, and carcinomas. The purpose of this study was to find out whether this classification is a useful criterion for determination of the extent of surgery. Our retrospective study included 5 cases of adenoma, 2 of atypical adenoma and 13 of carcinoma. All histological specimens were revised and were stained immunohistochemically for thyroglobulin. All specimens were positive for thyroglobulin; staining for factor VIII was performed in cases in which the tumor had penetrated into blood vessels. Hemithyroidectomy was used for typical adenomas, while atypical adenomas were treated as carcinomas and total thyroidectomy was performed. 5 patients were treated with radioactive iodine. Taking into account the clinical results, we conclude that histological subtype is a useful guide for proper surgical management. Hemithyroidectomy is proper therapy for adenomas. The management of atypical adenomas was not determined as all were treated as carcinomas.
