Hi- I have a one year old son who has had recurrent petechiael rashes since he was 5 months old. On a daily basis he has scattered petechiae from his neck to his groin- most severe around his neck. He has been to two hematologists, who found nothing abnormal in his bloodwork. He has been to a dermatologist who confirmed that he does have petechial rashes, but did not have an explanation. We are waiting for an appointment with a pediatric dermatology specialist (3 month wait to see him). This week my pediatrican found petechiae on my 3 year old daughter as well. What could be the cause of recurrent petechiae? Any ideas. I am stressed out.
