Une version plus simple :
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathmorphing}
\newcommand\randombox[1]{%
\tikz{%
\node[inner sep=1em,text width=.85\linewidth,align=flush left] (A) {#1};
\draw[decoration={random steps,segment length=0.4cm,amplitude=.1cm},decorate]
(A.north west) -- (A.north east) -- (A.south east) -- (A.south west) -- cycle;
}}
\begin{document}
\randombox{%
{\Large Mon text en large} mon text
