Résumé
Las mastocitosis son un grupo de enfermedades caracterizadas por la hiperplasia de mastocitos funcionalmente normales en diferentes tejidos. Se distinguen cuatro formas cutáneas: urticaria pigmentosa, mastocitoma solitario, mastocitosis cutánea difusa y telangiectasia macularis eruptiva perstans (TMEP). La TMEP es una forma de mastocitosis de presentación infrecuente en la infancia, que se caracteriza clínicamente por la presencia de máculas eritemato-castañas telangiectásicas. Su pronóstico es favorable y el tratamiento, de requerirlo, es sintomático y de índole estética. Presentamos dos casos inusuales de TMEP en la edad pediátrica

Here we present two unusual cases of TMEP in the infancy
