[|Human|] My son age 5 has had a bruise colored mark at base of his spine area for a couple years but never complained of pain so I figured it was some sort of birthmark. Lately it s been getting a little more visible and now is a soft lump if you run your fingered across it. It s no longer flat. It makes me very nervous it could be something worse. Please help.
[|AI|]  Hi it's mostly hematoma at the base of his spine, that is a collection of blood vessels. It is better you show him to your specialist once as it may be only a simple hematoma or one with underlying skeletal abnormality. Some increase in size as the child grows and later regress. Others which are not regressing May need steroid cream or laser therapy. Hope this is helpful to you, kindly rate it if so. Take care
