Contact dermatitis from plants

Does anyone know of a plant that can cause linear bruising, i.e. under the skin rather than on the surface, with no itching, blistering, soreness, pain, etc?  My 9 year old granddaughter noticed such bruising on her upper arm last week, which next day continued  down to her lower arm.  Spent a day at hospital having blood tests etc. (normal), then referred to a dermatologist who said it was probably a sting from a hornet or horsefly, which I doubted as they are usually very painful and there is swelling and puncture mark, which she doesn't have, and anyway next day a similar patch appeared on the other arm and she hadn't been outside in the meantime.  Then we discovered a schoolmate had almost identical bruise-like marks on one upper arm, now going further down, so back to hospital.  This time told it was contact dermatitis from contact with a plant, which again I find hard to credit as there is no inflammation or discomfort, just lines and patches of reddish purple bruising.  Does this ring any bells with anyone? 



  • Sorry Bouleversee I can't help you at all but I'm responding here so this gets bumped back up the list in the hope that someone can help/advise/confirm/refute for you. Doesn't sound like contact dermatitis to me though to be honest. Hope you get to the bottom of it. Heather

  • Thanks, Heather.  Drawn a blank so far.

    No bells at all Bouleversee. I've seen bites and allergies and irritations and all manner of things in my time but I don't recognise your description. Also I would have expected, as you did, pain or itching from anything plant/bite/sting related

  • Thanks, nutcutlet.  Strange, isn't it?

    Unless the children socialise outside school, I'd be looking at the school premises ....

    Is there a school garden,or area where they play outside that is planted?.Is it worth mentioning it to the school.?

  • The school has large grounds.  It has been notified.

  • My son used to get this reaction from batteries! All he had to do was take them out of his toy car or whatever and his face would swell up and look horrific with veins really showing and his skin looked almost transparent, anti-histimine given and he was fine within five minutes...really odd:/ If I touch Petunia's without gloves I get a nasty lumpy rash on the palm of my hand and it doesn't go away for weeks:/ 

  • No swelling or lumpy rash in this case.
