Hello. Thank you. My 12 month old baby girl has had a 1 centimeter palpable lump in front of her right shoulder, arm pit area. We first noticed it around month 8. Dr. Suggested we keep an eye on it for changes. No change in size and consistent blue/green hue on skin where lump is. Two weeks ago had ultrasound and received note from dr. today that radiologist states it is an enlarged lymph node, and referral will be made to children s hospital for pediatric surgeon consult for baby. Plan on seeing surgeon as soon as possible but in meantime if you are able to provide any additional info on possible cause. The lump does not appear to be painful and baby is thriving with no fever, etc...
