ABSTRACT

El carcinosarcoma de laringe es un tumor bifásico raro que representa menos del 1% de todos los tumores malignos de laringe. Debido a su doble naturaleza epitelial y mesenquimal esta neoplasia ha sido denominada de distintas maneras en la literatura, siendo indispensable el estudio mediante inmunohistoquímica para establecer un diagnóstico correcto. Se presentan 2 casos de carcinosarcoma de laringe, confirmados mediante estudio con inmunohistoquímica, ambos tratados mediante laringectomía total. Se elabora una discusión de los principales aspectos clínicos, histopatológicos y terapéuticos de esta infrecuente neoplasia.
