When talking about terms it should be with article (a/an) before the term? For example:
1 What is an urticaria?
or
2 What is urticaria?
Thanks!

If you have never heard the word urticaria, you simply ask: What is urticaria. It is totally irrelevant whether it is a mass noun or not, or a term or not. You don't know the word, so you don't know what kind of word it is.
It depends on the word you are asking about.
You would not use an article if you are asking about
"What is spaghetti?"
A proper noun, or a name.
"What is 'The New York Times'?"
A plural noun.
"What are fish?" or "What is a fish?"
In every other context, you would use an article.
As for the example you gave, "urticaria" is a mass noun, so you should say:
"What is urticaria?"
