get_the_term_list without specific category

I am using :

$term_link = get_the_term_list($post->ID, 'portfolio_category', '', '<br />', '');

to get the category and link to it.

There is any way to get all category despite specific one?

Now i get :

<a href="http://5.10.105.54/~shayjcoi/shayj/portfolio_category/Yellow/" rel="tag">Yellow</a></br><a href="http://5.10.105.54/~shayjcoi/shayj/portfolio_category/Main/" rel="tag">Main</a>

And i want to get all the category despite the “Main” category.
