title: [Angiomatoid tumor of the thyroid gland: primitive angiosarcoma or variant of anaplastic carcinoma?].
abstract: Thyroid gland angiomatoid tumors are an extremely aggressive neoplasms with varied histological patterns and features of endothelial differentiation. The histogenesis of thyroid angiomatoid tumors has been controversial for many years: these tumors may be either a variant of anaplastic carcinoma, or an angiosarcoma. We report a case of thyroid angiomatoid tumor in a 68-year-old woman. We also discuss, through a review of the literature, the pathologic criteria that could be used to distinguish between angiosarcoma and anaplastic carcinoma of the thyroid.
