Abstract

Peripheral primitive neuroectodermal tumors—also known as Ewing sarcomas—are a rare type of malignant tumor the histology of which characteristically reveals the presence of small round cells. Typically, t(11;22) translocation is observed. We describe the case of a 45-year-old man with a subcutaneous peripheral primitive neuroectodermal tumor in which the t(11;22) translocation was detected. He was satisfactorily treated with surgery and radiotherapy.

Key words:
peripheral primitive neuroectodermal tumor
Resumen

La familia del tumor neuroectodérmico primitivo periférico/sarcoma de Ewing (PNET/ES) representa a un grupo de neoplasias malignas poco frecuentes, incluidas dentro de un grupo de tumores que presentan característicamente en su histología células redondas de pequeño tamaño. La traslocación 11;22 es típica de este tumor. Se presenta el caso de un varón de 45 años con un tumor subcutáneo neuroectodérmico primitivo periférico, en el que se detectó la traslocación t(11;22), tratado satisfactoriamente mediante cirugía y radioterapia.
