Presentation of case material consisting of three patients, leads to a review of differenciated thyroid carcinomas ( DTC) with invasion of visceral axis of neck. Due to the fact that respiratory obstruction has an important incidence in DTC death - rate, and becausethese tumors ha< e low evolutive potential, it is reasonable to conclude that decisive action in favour of completeexeresis -including portions of visceral axisis fully justified. This fact is reinforced by the good long - term evolution of patients so treated. Analysisof usual characteristics of these invasive carcinomas comprises different aspects of tactic and technical interest, applicable to surgical treatment as outlined.

A propósito de tres •observaciones los autores revisan el tema de los carcinomas tiroideos diferenciados( CTD) con invasión del eje visceral del cuello. Puesto que la obstrucción respiratoria se muestra como una importante causade muerte en los CTD y que estos son tumores de bajo potencial evolutivo, es razonable concluir que una acción decidida en pro de sue
