what does hystionic mean?

my co-worker told me he was hystionic, and i asked if he didn't mean 'histrionic' he said no, and to look it up in a medical dictionary.so to spare me a trip to B%26N, what does hystionic mean? i cannot find the definition anywhere online.thank you
Answers:
I think it is histionic..and the word just means relating to any body tissue (histo- is a prefix for something relating to tissue). Maybe he did mean histrionic..

G'day Hfse,Thanks for the question.I assume he meant that you were hystrionic. The American Heritage Dictionary on Yahoo defines histrionic as: 1. Of or relating to actors or acting.
2. Excessively dramatic or emotional; affected.It is derived from Late Latin histrinicus, from Latin histri , histrin-, actor, probably of Etruscan origin. That is probably the sense that your co-worker meant it.There is also a histrionic personality disorder. The American Heritage Dictionary on Yahoo! defines it as A psychological disorder characterized by excessive emotionality and attention-seeking behavior.Your co-worker is obviously mistaken. You get very few results from a search engine for histionic and what you do get is typos for histrionic.You should seek to reconcile with your co-worker tomorrow so that you can settle any differences between you. You don't want to get your supervisor involved.I have enclosed some definitions of histrionic and histrionic personality disorder for your reference.I hope that things settle down for you in your workplace.Regards
