A 7 year old came in with this firm growth on her tongue, since birth. It's not painful but recently has gotten somewhat bigger. She also has a fullness under her left jaw since she was 3 months old. The mass is firm and looking close, clear fluid filled vesicles are evident. It seems to me to be lymphangioma circumscriptum, a cystic benign hamartoma of the lymphatic system. Any other ideas? We have worked with an amazing ENT from colorado who will be here in September and has agreed to remove it. Thank you Dr. King!
