Menu callback rendering node xxx
You have to call the same callback issued from node/%node menu i.e. node_page_view : 

function mymodule_menu() {
  $items = array();

  $items['mymodule/info'] = array(
    'title' =&gt; t('My module'),
    'description' =&gt; t('My module description'),
    'page callback' =&gt; 'node_7',
    'type' =&gt; MENU_CALLBACK,
  );
  return $items;
}


function node_7(){

include_once(drupal_get_path('module','node') . '/node.pages.inc');

return node_page_view(node_load('7'));

}
