My son was born with a cystic hygroma, which we did not know until he was a day old when it became noticeable on his neck. It came up again after that when he was 3 years old and now he is 14 and it has started to come up again. What would make it come up noticably now?
Hi....cystic aroma can grow back from remnants. It is not very uncommon to have recurrent cystic aroma in the same region. The treatment is surgical if the lesion is symptomatic or producing compression symptoms. Regards -
