Tuesday we had our 2nd appointment at CHOP (Children’s Hospital of Philadelphia). Our first appointment was December 2008 with the dermatologist, Dr. Yan. Although Hannah’s pediatrician could diagnose her birthmark as a Nevus Sebaceous, he wanted a specialist to confirm the diagnosis and to decide if she should have surgery to remove it. Dr. Yan had recommended that it be removed since it’s in a place where Hannah cannot see it easily to check on it for changes (it’s behind her right ear).
