A 20-year-old patient developed blisters after biting his lower lip, which is estimated to be the manifestation of mucocele. Generally, the scar formed after biting blocks the duct of the labial gland and forms a storage cyst. Don't pick it yourself, even if it will appear again in a few days, repeated explosions will only increase the difficulty of treatment.

Suggestion:

Oral and maxillofacial surgery is recommended. If it is a mucinous gland cyst, it is suggested to remove the cyst and suspected acinus as soon as possible under local anesthesia to avoid postoperative recurrence. I wish you the best of health!
