ABSTRACT

El neuroblastoma es el tumor maligno sólido extracraneal más común en niños. Sólo el 10 por ciento de los casos se diagnostican después de la primera década de vida. Presentamos una paciente afroamericana de 23 años, con una masa paravertebral en T3-T5, múltiples lesiones en los cuerpos vertebrales y una lesión expansiva en la región parietal derecha. El estudio inmmunohistoquímico (negativo para CD99, CD20, CD3 y desmina y positivo para cromogranina, sinaptofisina y NB84), confirmó el diagnóstico de neuroblastoma. La paciente fue sometida a 12 ciclos de quimioterapia recibiendo VAC (vincristina / doxorubicina/ cyclofosfamida) intercalada con ICE (ifosfamida/ mesna/ etoposido). La doxorubicina fue reemplazada por actinomicina en el séptimo ciclo. La paciente toleró bien la quimioterapia y está clínicamente estable.


Neuroblastoma is the most common extracranial solid malignancy in children but rarely described in adults, being 10 percent of all cases diagnosed after the first decade of life. We report a 23 year-old black woman with a mass at paravertebral region of T3-T5, multiple lesions in vertebral bodies and expanding skull-brain lesion at the right parietal region. Immunohistochemical analysis (negative for CD99, CD20, CD3 and desmin; and positive chromogranin, synaptophysin and NB84) confi rmed the diagnosis of neuroblastoma. The patient was submitted to 12 cycles of chemotherapy receiving VAC (vincristine/doxorubicin/cyclophosphamide) interspersed with ICE (ifosfamide/mesna/etoposide) and doxorubicin was replaced by actinomycin in the 7th cycle. She had good tolerance to this therapy, and has been clinically stable.
