title: Leiomyosarcoma of the thyroid gland.
abstract: The existence of primary thyroid sarcomas represents a contentious issue. Some authors believe that thyroid sarcomas are, in fact, anaplastic carcinomas with sarcomatous (spindle cell) features. From the standpoint of treatment and prognosis, the histogenesis of thyroid 'sarcomas' is academic, because these tumors, irrespective of the therapeutic intervention, are lethal 1. Primary thyroid leiomyosarcomas are extremely rare. Only nine isolated cases have been reported in the literature and such tumors carry a very poor prognosis [1-7] .
