Signo de Nikolski - Overview

Definición:

Es un hallazgo cutáneo en el cual las capas superiores de la piel se desprenden de las capas inferiores de la misma cuando hay una ligera fricción.

Consideraciones generales:

El signo de Nikolski es ya sea positivo o negativo. Un resultado positivo puede estar presente en varias enfermedades diferentes. Las personas con un signo positivo tienen piel floja que se desprende de las capas subyacentes cuando hay fricción. El área por debajo de la piel es de color rosa y húmeda y por lo regular es muy sensible.

Normalmente, el médico comprobará la presencia de este signo simplemente retorciendo el borrador de un lápiz contra la piel. Si es positivo, por lo general en cuestión de minutos se forma una ampolla en el área.
