Abstract (English): The neuroblastoma-like schwannoma is considered a very rare variant of schwannoma, and represents a diagnostic challenge given its low incidence and few reports. We present the case of a 40-year-old woman with a painful nodule with progressive growth in the anterior thoracic wall. After histopathological and immunophenotypic analysis, and a literature case review, with emphasis in the differential diagnosis and immunohistochemical analysis, the diagnosis of neuroblastoma-like schwannoma was made.

Abstract (Spanish): El schwannoma neuroblastomoide formador de rosetas se considera una variante del schwannoma y representa un reto diagnóstico, dada su baja incidencia y los escasos reportes en la literatura. Se presenta el caso de una mujer de 40 años con un nódulo doloroso de crecimiento progresivo localizado en la pared anterior del tórax. Después del estudio histopatológico e inmunofenotípico, y de una revisión de los casos reportados en la literatura con énfasis en el diagnóstico diferencial y la inmunohistoquímica, se diagnosticó un schwannoma similar al neuroblastoma y formador de rosetas.
