[|Human|] My 3 year old son has a hard skin tag under his tongue that looks reddish purple. I am not sure what caused it. Its been there for more than a week. He doesnt complain of pain, but I am very concerned about this. He pediatrician has asked us to wait and watch. Can someone please tell mw what this is? Thank you.
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concern. As per your complaint a hard skin tag under the tongue that looks reddish purple can be most commonly be a Muscle that is a mucous cyst and is formed due to ruptured duct of the salivary gland leading to accumulation of mucous into the soft tissues and thus forming a lump or due to clogging of the duct of the salivary gland leading to formation of a mucous filled lump. Other cause can be hematoma formation that can occur due to traumatic injury under the tongue. Both are completely harmless and also self resolving. Make him do salt water rinses. In case if it does not improve in a week then you should not worry and move ahead to get it removed surgically without any problem. Hope this information helps. Thanks and regards. Chat Doctor.
