urticaria pigmentosa

My daughter has been diagnosed with urticaria pigmentosa, however the more I read the more I doubt if this is correct. She does not itch them and they do not swell - can any one else confirm that this may be the case?

In urticaria pigmentosa,the rash consists of reddish-brown spots that turn into hives when they are rubbed hard or scratched. Sometimes the spots will blister.When the rash turns into hives,then there is associated itching.Diagnosis is by Darier sign and confirmation is done by skin biopsy.So I would suggest a skin biopsy to confirm the diagnosis.

Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.
