Kiesselbach's plexus is the main site for which of these conditions?

Regarding the above - it is a rare condition called hereditary hemorrhagic telangiectasia (HHT) or Osler Weber Rendu syndrome.

Was about 8 when my mom had to have my nose cauterized to stop frequent nose bleeds. Then 25 years later, while testifying in court, (against a driver who PURPOSELY killed a biker) & being "emotionally beat & whipped" by the defense attorney...my nose started bleeding while on the stand...they had to stop proceedings...the above condition is no joke!
