ABSTRACT

El sarcoma de Ewing forma parte de una familia de tumores que se caracterizan por presentar translocaciones que involucran al gen EWS y algún miembro de la familia ETS que posee un dominio de unión al ADN. Se presenta el caso de un paciente de dos años de edad con una masa cervical de crecimiento rápido que por compresión local comprometió estructuras nerviosas manifestándose inicialmente con un retardo en el neurodesarrollo. Se diagnosticó Sarcoma de Ewing/Tumor neuroectodérmico primitivo por biopsia. Este es un tipo de tumor raro con una presentación inusual a nivel cervical; el cual debe tenerse en cuenta al momento de evaluar pacientes con masas cervicales en especial las de crecimiento rápido con el fin de dar un tratamiento preciso y oportuno.


Ewing's sarcoma is part of a family of tumors that is characterized by translocations that involve the EWS gene and a member of the ETS family that has a DNA binding domain. The case of a two-year-old patient who was admitted in our institution because of a rapidly growing cervical mass associated to neurodevelopment setback and functional gradual loss due to nerve compression. Ewing's sarcoma / primitive neuroectodermal tumor was diagnosed by biopsy. This is a rare type of tumor with an unusual presentation in this location; which should be taken into account when assessing a patient with cervical masses, especially those of rapid growth in order to provide an accurate and opportune treatment for improving outcomes.
