[|Human|] My grandson is two years old, he was at my house and when his mom came to pick him up we noticed a huge bruise just at the top of his back thight right below his buttock, his mother called and said that the bruise had completely disappeared, in the space of 45 minutes and it is gone, should we take him to the ER?
[|AI|]  Hi... Please take him to the emergency room. Hi....by what you quote I feel that the kid might be having a bleeding disorder, either congenital or acquired... Mostly congenital, considering the age of presentation. The bluish discoloration you are noticing is a subcutaneous bleed or bruise and the small lump you are able to palpate is a subcutaneous blood clot. Your grandchild needs evaluation and I suggest you take her to the nearest emergency room as soon as possible. This I am suggesting because - if the kid has a spontaneous bleeding like this internally, as she might require emergency blood products. Regards -
