Tree with linked structure and node leafs
Solved!

I have used this piece of code, palced on the "header" of the view, to obtain my goal:

$term = taxonomy_get_term(arg(1));
$parent = current(taxonomy_get_parents(arg(1)));
$name = $term-&gt;name;
echo "&lt;h5&gt;".$parent-&gt;name."&lt;/h5&gt;"; //topic
echo "&lt;h2&gt;".$name."&lt;/h2&gt;"; //subtopic
$breadcrumb = array();
$breadcrumb[] = l('Home', '&lt;front&gt;');
$breadcrumb[] = l('Topic', 'Topicview');
$breadcrumb[] = l(drupal_get_title(), base_path() . request_uri());
drupal_set_breadcrumb($breadcrumb);
