We had a biopsy done 3 years ago and the 1st Dermotologist said it was Neavous Sebaceous and not to worry. Applied Steriod cream for 2 weeks and seem to heal the oozing & crusty stuff but never went away. 2nd Dermotologist said that it could not possibly be Neavous Sebaceous because there was a hair in the sample area they removed. Now 3 years later she is 10 and it is inflamed, oozing, crusty, painful, and 1.5" in length. We had a 3rd Dermotologist look at it, but he wants to go off the old biopsy results so we are waiting. Can you give me any information?
