Perineuroma maligno (tumor maligno de vaina nerviosa periférica, perineural). Estudio inmunohistoquímico de un tumor poco frecuente, utilizando EMA, GLUT-1 y Claudina-1, como marcadores de diferenciación perineural

Only a small proportion, probably less than 5% of MPNST have been shown to demonstrate perineurial cell differentiation, and they have been called malignant perineuriomas. EMA, Glut-1 a, Claudin-1 are used as immunohistochemical evidence of perineurial cell differentiation. The limited follow-up data available suggest that the malignant peirneuriomas may have a better prognosis than the conventional MPNST
