Page node edit content-type
You need to use function hook_preprocess_HOOK.

function themeName_preprocess_page(&amp;$vars) {
    if (!empty($vars['node']) &amp;&amp; arg(2) == 'edit') {
    $vars['theme_hook_suggestions'][] = 'page__node__' . $vars['node']-&gt;type .'__edit';
  }
}


This allowed me to use: page--node--[contentType]--edit.tpl.php
